6.0 PRINCIPLES OF OPERATION

6.0.1 Viewing the Sampler Interface 

 Main Menu Screen 

It displays various operating parameters of the system when the sampler is running. It is the 

primary screen to perform all the tasks necessary to obtain and input all the data necessary 

to maintain the sampler and collect samples. It shows the operating status of the sampler 

by displaying: 

 The current date and time. 

 A countdown timer shows when the next scheduled program will start. 

 Whether the timer is not executing or set to start at some future time. 

 The Keypad 

It allows data to be input into the HIGH-VOL+ to configure the various operating parameters 

of the sampler. 

 Power Status Light 

It allows data to be input into the HIGH-VOL+ to configure the various operating parameters 

of the sampler. 

 Alert Status Light 

It indicates the alert state of the sampler. The sampler monitors several operating 

parameters and alerts the user to take action when these parameters fall out of the 

expected range. A flashing red light indicates that a non-fatal alert has occurred. The 

sampler will continue to operate but may not be functioning optimally. A solid red light 

indicates a fatal alert has occurred and will not continue to operate. Use the INFO key on 

the main status screen to determine the source of the alert. 

 The Main Menu Function Keys 

The function keys (F1, F2, F3, and F4) from the main display are directly below the main 

menu screen. They are used to access the various information and configuration screens of 

the sampler. For what each of the keys use is, refer to Table 1.

6.1 PROCEDURES FOR SAMPLER SETUP 

6.1.1 Procedure for Pre-Installation Inspections and Operational Checks 

1. Check the sampler for completeness of system components and verify that it 

is in proper operating condition prior to transporting and installing at an air 

monitoring site. Proper operating condition of the temperature sensor, 

barometric pressure sensor, flow rate pressure sensor (Pcal), and ambient 

system flow rate is established for accuracy. 

2. Test a new sampler in-house prior to installing at a site. 

3. Refer to the TISCH Environmental HIGH VOL+ Operator’s Manual Version 5 

Firmware, if needed for detailed assembly, installation, and setup guidance. A 

hard copy of this manual is located in the AMU Shop and an electronic copy is 

on the TISCH Environmental website: www.tisch-env.com

 NOTE: The manufacturer recommends the following cleaning and 

maintenance activities to be observed until a stable operating history of a 

sampler is established. 

4. Inspect all gaskets (including motor cushion) to assure they are in good shape 

and that they seal properly. 

 NOTE: Gaskets must function properly and retain their resilience for the 

inlet to seal properly and replace when necessary. 

5. Inspect power cords for good connections and for cracks and replace when 

necessary. 

 CAUTION: Do not allow power cord or outlets to be immersed in water. 

6. Inspect the filter screen and remove any foreign deposits. 

7. Inspect the filter media holder frame gasket each sample period. This gasket 

must make an airtight seal. 

8. Ensure the elapsed time indicator is operating. 

9. Inspect inside of hood and internal components for foreign debris, such as 

dirt, dust, and/or insects after each sample period. Clean with paper towels 

and a light solvent and water solution. 

 NOTE: The TISCH HIGH-VOL+ TSP samplers are not able to achieve the 

selected flow rate of 40CFM in Ambient flow conditions at air monitoring sites 

above 602m (1975ft) with a standard 110V blower motor. TISCH recommends 

outfitting samplers operating at that elevation or above with a 220V blower 

motor. Information regarding any change to a sampler is documented in the 

sampler’s log book. See Attachment B: Technical Note 001 from Tisch 

regarding high altitude sampling considerations.

6.3.2 FLOW RATE CALIBRATION 

 The flow rate calibration is performed after the temperature and barometric sensors have 

been verified to be within acceptable tolerance of error (refer to section 6.3 “Calculations 

and Tolerances in Error”). The EPA’s guidance for this calibration is performed annually 

at a minimum, but ADEQ calibrates this equipment once every three months due to 

variation in seasonal temperatures and barometric pressures. Refer to Attachment A for 

the field data sheet for an aide regarding this procedure. 

1. Setup the following equipment/supplies: 

 3 pieces of tubing connected to T-fitting 

 Digital or water manometer with one end of tubing connected to (-) port, 

one end of tubing to AUTOCAL (top) on sampler, the third end is for the 

calibration orifice 

 Calibration orifice 

2. Install an 8” X 10” glass-fiber filter and the calibration orifice. 

3. Turn the motor on using the MTR CONTROL and MTR SETPOINT menu items in 

the Diagnostics Menu. Do this through the MTR CONTROL menu and select 

FIXED and then MTR SETPOINT. Set to 50%. The sampler and the motor are to 

be powered on for a minimum of 30 minutes before performing any flow 

calibration. 

 NOTE: The system is to be calibrated immediately after the motor warms up. 

4. Conduct a leak test by covering the hole on top of the orifice and pressure tap on 

the orifice with hands. Listen for a high-pitched squealing sound made by 

escaping air. If this sound is heard, a leak is present and the calibration top plate 

wing nuts need to be re-tightened. 

 CAUTION: Do not run the sampler for longer than 30 seconds at a time with 

the orifice blocked in order to reduce the chance of the motor 

overheating. 

 WARNING: Do not try this leak test procedure with a manometer connected to 

the side tap on the calibration orifice or the blower motor. If this is 

accidently done, liquid from the manometer could be drawn into 

the system and cause motor damage. 

5. Connect the tubing from calibrator to Auto Cal port on bottom of HIGH-VOL+ 

control and the digital or water manometer. 

6. Press the F3 key from the Main Screen to enter the SETUP menu. 

7. Use the arrow keys to scroll and select the CALIBRATE menu item and press the 

ENT key.

8. Select Qstd and press the ENT key. This will enter the Qstd calibration screen. 

9. Press the F1 key from the Qstd calibration screen to add calibration data and 

begin the calibration process. The system will prompt ENTER CALIBRATOR 

STANDARD m:

10. Enter the value from the orifice transfer calibration worksheet for Qstd Slope (m) 

and press the ENT key. If this information has been previously entered, it will be 

saved in this menu. 

11. The system will prompt ENTER CALIBRATOR STANDARD b: Enter the value 

from the orifice transfer calibration worksheet for Qstd intercept (b) and press the 

ENT key. If this information has been previously entered, it will be saved in this 

menu. 

12. The system will display “ENTER HI FLOW RATE”. The system will calibrate using 

this point as the high flow rate. The high flow rate for calibrations done at the 

Miami Golf Course (MIGC – 16629) is 39.6 CFM. The high flow rate for 

calibrations done at the Globe Highway (HAGH – 16593) is 41.8 CFM. These flow 

rates (expressed in standard conditions) are equivalent to 

 NOTE: Since the typical sample collection flow rate is 40 CFM (ambient) and the 

system calibrates in standard conditions, the annual variability of temperature and 

pressure must be accounted for in order for the set point to be oriented in the 

middle of the calibration range. This is why the high flow rates vary from site to 

site. Refer to Attachment B for a more detailed discussion of the appropriate 

calibration range to use at high altitudes. 

NOTE: If this information has been previously entered, it will be saved in this 

menu. If a different HI FLOW RATE is required, enter that value and press the 

ENT key to continue. 

13. The system will prompt “ENTER LO FLOW RATE”. The system will calibrate this 

lowest flow rate. The low flow rate for calibrations done at the Miami Golf Course 

(MIGC – 16629) is 32.4 CFM. The low flow rate for calibrations done at the Globe 

Highway (HAGH – 16593) is 34.2 CFM. 

 NOTE: Since the typical sample collection flow rate is 40 CFM (ambient) and the 

system calibrates in standard conditions, the annual variability of temperature and 

pressure must be accounted for in order for the set point to be oriented in the 

middle of the calibration range. This is why the low flow rates vary from site to 

site. Refer to Attachment B for a more detailed discussion of the appropriate 

calibration range to use at high altitudes. 

NOTE: If this information has been previously entered, it will be saved in this 

menu. If a different LO FLOW RATE is required, enter that value and press the 

ENT key to continue. 

14. The motor will now turn on and warm-up for 120 seconds. The system controls 

the motor speed to maintain the pressure across the calibration orifice at the 

desired starting point.

15 

 NOTE: The system uses the HI and LO values to calculate the 5-target flow rates 

used during the flow calibration process. The system automatically monitors the 

data during this calibration process and once the flow rate is stable at that 

operating point it will collect a data point. The system will move to the next 

calibration flow rate point once the previous point is obtained. The system will 

continue this process until all the points have been obtained. The internal CPU 

will generate the calibration values immediately following the collection of the fifth 

point, and display them on the Qstd calibration screen. 

15. On the Qstd calibration screen is the R-value, A1-value, and A0-value. The Rvalue shown on the screen has to be greater than 0.990 or else the calibration 

process needs to be repeated. 

 NOTE: If the R-value is greater than 0.990, record it on the data sheet along with 

the A1-value, and A0-value. 

16. Press the F4 key to exit the calibration screen and select Save to complete the 

calibration process. 

17. Press the ESC key twice to return to the Main Screen. 

18. Remove calibration orifice and filter. 

19. Fill out the Instrument and Site Logbook to document the visit and service 

performed to include the relevant R-, A1-, A0- values for the calibration that was 

just performed. 

20. Download the calibration data file to retrieve the event details for the calibration by 

going through the DATA (F2) tab and select SAVE. Once it is finished press ESC

key twice to return to the Main Screen. 

21. Retrieve the file from the memory card by transferring the file to a computer 

compatible for viewing .QCL data files (Excel does this). This file will need to be 

uploaded to ADEQ’s database (J drive) for future reference. 

22. Open the file and sort the text into separate columns. This can be done by using 

the “text to columns” feature from the data drop down menu. First highlight the 

data, then in the data drop down menu select text to columns and select the 

delimited data option. Check the comma delimiter option and finish. This should 

split the data into separate columns. The respective column headers are as 

follows: Date and time, Unit Serial Number, Calibration Task, Orifice M, Orifice B, 

Data Point, Flow Set Point, Tamb, Pamb, Pdif, Pcal, Hotwire ADC Value, System 

Measured Flow Rate, and Calibrator Measured Flow Rate. 

23. Transfer the respective information from this file to the calibration worksheet to 

complete the table. Information such as time started and ended, Pressure, 

Temperature, Pcal, System Measured Flow Rate, and Calibrator Measured Flow 

Rate need to be transferred to the table on the worksheet. The System Measured

2. Install a glass-fiber filter and the calibration orifice. 

3. Turn the motor on using the MTR CONTROL and MTR SETPOINT menu items in 

the Diagnostics Menu. Use the MTR CONTROL to go to FIXED and MTR 

SETPOINT. Set to 50. The sampler and the motor are to be powered on for a 

minimum of 30 minutes before performing any flow calibration. 

NOTE: The flow rate is to be verified immediately after the motor warms up. 

4. Conduct a leak test by covering the hole on top of the orifice and pressure tap on 

the orifice with hands. Listen for a high-pitched squealing sound made by 

escaping air. If this sound is heard, a leak is present and the top loading adapter 

hold-down nuts need to be re-tightened. 

 NOTE: Avoid running the sampler for longer than 30 seconds at a time with the 

orifice blocked. This reduces the chances of the motor overheating. 

 CAUTION: Do not try this leak test procedure with a manometer connected to the 

side tap on the calibration orifice or the blower motor. Liquid from the manometer 

could be drawn into the system and cause motor damage. 

5. Connect the tubing from calibrator to Auto Cal port on bottom of HIGH-VOL+ 

control and the digital or water manometer. 

6. Press the F3 key from the Main Screen to enter the SETUP menu. 

7. Use the arrow keys to scroll and select the DISGNOSTICS menu item and press 

the ENT key. 

8. Select MTR CONTROL and press the ENT key. 

9. Select Qsys from the list of available motor control methods. This will tell the 

system to control the motor in the same way as it is controlled during a timer

controlled run. The system will also prompt for wait conditions the flow will be 

controlled under (ambient or standard). 

 NOTE: Select the AMB conditions in order to match the normal operating 

conditions for a sample collection. 

10. Make sure the flow rate is set to a value that can be achieved by the filter media. 

Failure to do this can result in premature wear of the components in the system. 

11. Select MTR SETPOINT and press the ENT key. The system will prompt for a 

desired set point. The units of measurement and the valid ranges for this field will 

change based on the current setting on the MTR CONTROL. For Qsys, the units 

of measure are in CFM. Enter the flow rate to be verified and press the ENT key. 

 NOTE: During a normal sample collection the value is 40 CFM. 

 NOTE: After pressing the ENT key in the previous step, the motor will turn on and 

begin to control the flow rate. 

12. Allow the system to run for approximately 10 minutes before continuing. 

13. Record the detected flow rate five times (at approximately 3 minute intervals) from 

both the Pcal output on the instrument’s display and the water manometer 

(simultaneously). 

14. Press the ESC key twice to return to the Main Screen. 

15. Remove calibration orifice and filter. 

16. Fill out the Instrument and Site Logbook to document the visit and service 

performed. Complete the AMU Tisch High Volume TSP Pb Air Sampler Data 

Sheet upon return to the office and submit to the AMU Field Sheet Coordinator. 

See Figure 2 for an example of a completed sheet. 

 NOTE: If a significant error is seen between the reading on the sampler and the 

water manometer, the following are some of the possible causes: 

 Verify that the flow rates are in the same samplers of measure and at the 

same measurement conditions (i.e. standard or ambient). 

 Check the system for leaks. 

 Check the filter for tears. Tears can create a localized increased flow rate 

and affect the flow rate seen by the probe. 

 Verify the calibration of the flow reference. 

 Verify that the Tamb, Pamb, and Pcal sensors used by the flow control 

(and calibration) of the system are within tolerance of error.

6.4 CALCULATIONS AND TOLERANCES IN ERROR 

When performing a flow and sensor verification and/or calibration, several calculations are used 

for these tasks. The ADEQ Tisch High-Volume TSP Pb Sampler Verification/Calibration Data 

Sheet has been developed (see Attachment A) for the ease of completing the quality assurance 

checks for the instrument’s performance to specified tolerances of each sensor, which are listed 

in each of the sections below. The work sheet automatically does the calculations listed below, 

but in the case of it not being accessible they are provided here. The work sheet has also been 

formatted to give feedback by changing the cell’s color for the conditions of the tolerances set 

forth for each sensor. Green indicates the sampler is operating within required specifications as 

per 40 CFR Part 58 and a calibration is not necessary, amber indicates it is approaching the 

limits of tolerance and calibration is recommended, and Red means that a sensor is out of 

tolerance, and calibration is required. Notify the Data Management & Quality Assurance 

Sampler of the exceedance of tolerable error upon submittal of Data Sheet to supervisor. 

6.4.1 Instrument’s date and time versus the actual 

 The date and time on the instrument is compared with the actual date and time from a 

standard chronograph, like from a cellular service provider. The date should reflect 

exactly what day it is. The comparison of the time should be plus or minus 2 minutes 

between each other. If the instrument’s reading is over or under 2 minutes, change it to 

reflect the actual time. 

6.4.2 Temperature sensor verification 

 The instrument’s output is compared with a standard reference’s reading, like a BGI 

Tetracal. The difference between these two readings should be less than 2 ̊C. If the 

instrument’s reading is over 2 ̊C, calibrate the temperature sensor using the calibrate 

menu and change it to reflect the actual conditions on the standard reference. 

6.4.3 Barometric pressure sensor verification 

 Similar to the temperature, the output on the instrument is compared with a standard 

reference. The difference between these two readings should be less than 10mmHg. If 

the instrument’s reading is over 10mmHg, calibrate the pressure sensor using the 

calibrate menu and change it to reflect the actual BP. 

6.4.4 AutoCal (Pcal) sensor verification 

 The flow rate is displayed in the Pcal output when the calibration orifice’s port is 

connected to the AutoCal port. The comparison of this sensor to a digital or water 

manometer should be ±5% difference in error. The calculation is listed below. If the 

percent difference is greater than 5%, calibrate the AutoCal (Pcal) sensor using the 

directions listed above.

6.4.5 Flow rate verification 

The output for the flow rate on the controller (Pcal) is in inches of water (inH2O). This 

needs to be converted to CFM in order to be directly compared to the set point. The 

conversion calculation is listed below. The comparison of the set point and the 

measured flow rate from the reference standard should be less than 5% difference in 

error. A measured flow rate greater than 7% difference means the instrument flow rate 

exceeds the tolerable error established in the CFR and is cause for data invalidation. To 

prevent this, anything greater than 5% difference in measured flow rate is cause for the 

calibration points to be corrected. 

Note: (inH20) is measured from an external manometer 

 

 Nomenclature: 

 Qstd – standard flow rate 

 Qamb – ambient flow rate 

 Pamb – ambient barometric pressure (mmHg) 

 Tamb – ambient temperature (Kelvin) 

 Tstd – 298°K 

 Pstd – 760mmHg 

Conversion from (m3/min) to CFM = 

 Qstd (m3

/min) * 35.3 CFM 

Ambient Flow Calculation (Qsys) (m3/min) = 

 1 

 (orifice’s slope m) √ (((inH20) (Temp(K) / BP(mmHg))) - (orifice’s intercept b)) 

Percent difference =

Conversion from Qstd to Qamb = 

 Qstd = Qamb ((Pamb / Pstd)*(Tstd / Tamb))

6.5 TROUBLESHOOTING & MAINTENANCE 

6.5.1 Corrective Maintenance Procedures 

The following is a list of possible problems and the corrective measures. 

i. Shelter/Sampler Exterior: There is nothing on the anodized aluminum shelter that is 

should wear out under normal operating conditions. In the event a system is dropped or 

blown over, some shelter parts may become bent. Simply re-shape the bent 

component(s) or replace them as necessary. 

ii. Blower motor: If the blower motor does not function, perform the following test: 1. Unplug 

the motor from the flow control device or timer. 2. Plug the motor directly into line 

voltage. If the motor does not operate when plugged directly into line voltage then: See 

“electrical hook-up” schematic. If the motor still does not work, see timer and flow control 

instructions. 

iii. Filter holder: Two gaskets make contact with the filter holder. The 8”x10” gasket seals 

between the shelter base pan and the flange of the filter holder. If this seal is 

compromised, replace the 8”x10” gasket. The lower section of the filter holder is sealed 

against the blower with a round neoprene rubber gasket. If any leakage is evident, 

replace this gasket. 

iv. Filter media holder: The filter media holder uses the 8”x10” gasket to seal between it and 

the filter holder. Another 8”x10” gasket is also used on the filter media holder to seal 

between the filter holder down frame and the filter media itself. If leakage is evident, 

inspect the gasket for foreign objects and replace as necessary. 

6.5.2 Routine Maintenance Procedures 

A regular maintenance schedule will allow a monitoring network to operate for longer periods of 

time without system failure. Adjustments in routine maintenance frequencies will be made once 

a strong operating history is established and based upon the operational demands on the 

sampler(s). 

Cleaning and maintenance activities to observe during each site service visit. 

i. Inspect all gaskets (including motor cushion) to assure they are in good shape and that 

they seal properly. For the inlet to seal properly, all gaskets must function properly and 

retain their resilience. Replace when necessary. 

ii. Power cords should be periodically inspected for good connections and for cracks 

(replace when necessary). 

CAUTION: Do not allow power cord or outlets to be immersed in water. 

iii. Inspect the filter screen and remove any foreign deposits. 

iv. Inspect the filter media holder frame gasket each sample period. This gasket must 

make an airtight seal.

v. Ensure the elapsed time indicator is operating by watching under power. 

vi. Inspect inside of hood and internal components for foreign debris, such as dirt, dust, 

and/or insects after each sample period. Clean with paper towels and a light solvent and 

water solution. 

The manufacturer’s operating manual includes more detail on troubleshooting using the 

Diagnostics Screens and error codes. If a problem cannot be identified and corrected, notify the 

Team Leader or Supervisor. 

NOTE: Upon performing a review of the sampler’s data, the power log must be 

reviewed for power surges that may have affected the sampler during the sample 

collection period. If a power failure occurs during a collection period, keep an objective 

watch on the issue until resolved. The following power-related error codes are pertinent 

to troubleshooting an issue that may have occurred with the sampler or the power 

source. 

a. 130 = 128( Power On Reset) + 2 (Low Voltage Detect) 

 When the sampler is powered on, you will almost always get a ‘Power On 

Reset’ and ‘Low Voltage Detect’. 

b. 64 = External power reset 

 External Reset occurs because the reset line on the processor was pulled 

low. This is caused by a surge or spike in the power supply. 

c. 32 = Watchdog reset 

 Watchdog Reset occurs when a part of the program is taking too long to 

execute and the system resets itself to try to regain control. 

Most of the power failures that last less than one minute are simply the result of 

the system restarting the software after a surge in the power supply. When this 

occurs, there is not a problem with the instrument.

6.6 SAMPLE COLLECTION AND FILTER EXCHANGE

6.6.1 Installing Filters: 

1. Collect the transport cases for the upcoming sample run day in the Air Filter Lab (AFL) 

staging area. A spare case is provided in the event a filter is damaged during the sample 

filter exchange process. Visually check the cases to ensure the filter cassette and ADEQ 

LeadTSP Air Sampling Record are enclosed. 

2. Disengage the sample saver shield in the DIAGNOSTICS menu for ease of installing the 

filter. 

NOTE: A sample (exposed filter) will probably be in the sampler at this time. Remove it 

following the directions below for Retrieving Filters. 

3. Remove the unexposed filter cassette from the transport case. Visually inspect the filter 

for pinholes, chaff or flashing, loose material, discoloration, and uniformity. 

4. Carefully place the filter cassette in the sampler and tighten the wing nuts evenly on 

alternate corners; under-tightening may result in leakage, over- tightening may damage 

the gasket and cause the filter to stick to the gasket. Also be sure to tighten the filter 

holder thumb screws so they are snug with the top plate. 

5. Check the timer to ensure that it is set to start the sampler at midnight and to stop the 

sampler at midnight the next day. The normal sampling period is 1440 minutes. 

NOTE: Care must be taken to ensure that the filter is clean and undamaged before it is 

installed in the sampler. Do not remove the faceplate until the sample saver shield has 

been engaged. The filter must be keep clean and never touched with fingers. 

6. If the filter is bad, exchange the filter with the spare filter cassette that is provided, mark 

the changes on the chain-of-custody, and repeat steps again. 

6.6.2 Retrieving Filters: 

1. Open the shelter lid and install the filter faceplate to protect the filter while it is being 

handled. 

2. Disengage the sample saver shield by accessing the control in the DIAGNOSTICS 

menu. 

3. Carefully loosen the filter holder wing nuts and remove the filter cassette. 

4. Place the filter cassette in the protective containers, i.e. plastic bag and transport case. 

NOTE: The filter must be keep clean and never touched with fingers. 

5. Record the sample date using military time (24 hour clock), total sample time and other 

sample period data (flow rates, temperatures, pressures, %CV, and total volume) on the 

associated ADEQ LeadTSP Air Sampling Record and place in the transport case.

NOTE: If a mistake is made, draw a single line through the entry, initial and date. Enter 

the correct information adjacent to the mistaken entry. 

If there are multiple mistakes made - a new form can be issued if needed by the 

AFL. 

6. Perform a quick review the sampler’s summary and interval data while at the site to 

verify that the sampler ran the correct amount of time and the flow rate was within 

tolerance. 

a. Instructions for viewing and downloading data are found in section 6.1.7 and 

6.1.8. 

b. If the data show that the sampler was out of tolerance on these criteria, setup 

a make-up sample if there is sufficient time to collect and retrieve a sampler 

before the next scheduled run day. Use the unexposed filter and chain-ofcustody/field data sheet provided for the appropriate sampler and next run 

day. AFL will set up a replacement filter and paperwork for the appropriate 

sampler’s next regularly scheduled run day. 

c. If there is not sufficient time to collect a makeup sample prior to the next 

regularly schedule run day, do not set up a makeup sample. 

NOTE: An additional sample may be collected during the quarter to supplement for the 

lost run day. Work with DM&QA to determine how best to handle each missed sample 

on a case-by-case basis. 

7. Fill out the Instrument Logbook to document the visit and service performed. Complete 

the Site Log Book form and remove and return the top white sheet to AMU field sheet 

coordinator. 

8. Return each transport case containing the filter sample and the ADEQ LeadTSP Air 

Sampling Record (chain-of-custody/data card) to the AFL staging area. See Figure 3 for 

an example of air sampling record sections to be completed by the operator. 

9. Store the downloaded data to J drive under the appropriate site folder located at:

5.0 HEALTH & SAFETY PRECAUTIONS 

 Follow safety precautions outlined below. If a site is found damaged due to weather, vandalism, 

or other reasons and/or a health & safety concern is identified, contact the DM&QA Manager. 

Do not proceed with work if a hazardous condition exists. There are no unusual hazards 

associated with the operation of this sampler; therefore, no special safety training or certification 

is required. 

 Employ normal safety measures to avoid electrical shock. Avoid standing in water when working 

with electrical equipment. Use properly grounded electrical cords and extensions. The power 

source for this sampling system must be a 3-wire grounded circuit. 

 Use caution when working on elevated surfaces and platforms to avoid slips, trips and falls. 

 Do not touch hands to eyes, ears, nose or mouth before washing hands after handling sampling 

media (setting up or removing sample). Use conventional practices for good personal hygiene 

and do not smoke, eat, or chew gum before washing hands 

INTERFERENCES: The performance audit of the sampler typically takes 3 - 5 minutes, but wind 

interferes with the pressure sensor and causes the audit to take longer 

6.0 EQUIPMENT & SUPPLIES 

 Audit orifice standard with calibration relationship in actual CFM and traceable to NIST. 

o NOTE: This orifice standard must not be the same one that is used for routine 

calibrations and flow checks 

 Slack-tube manometer and/or a digital flow meter 

 Thermometer 

 Barometric Pressure Gauge 

 Clean 8” X 10” filter of same media as that used for routine sampling 

 TSP Lead Sampler Audit sheet (Attachment 1) 

6.0 PROCEDURE 

6.1 Transport the above equipment to the monitoring site.

6.4 Cover the filter cassette with the audit faceplate to protect the integrity of the filter. Do not touch 

filter membrane. 

6.5 Loosen the filter cassette wing nuts evenly on alternate corners and check that the gaskets are in 

good condition (not deteriorated). Remove the filter cassette from the sampler taking care not to 

touch the filter membrane. 

6.6 Place the filter cassette carefully inside a secure holder such as a clean, plastic bag to further 

protect it from exposure to debris or damage from weather. 

6.7 Install the audit filter cassette and orifice standard, making sure the orifice gasket is present and 

the audit orifice is not cross-threaded on the filter cassette. 

6.7.1 Seal the audit orifice's pressure port with a rubber cap or similar device. 

NOTE: A leak may occur if the audit filter cassette is not seated properly. A leak on this 

sampler is detected by hearing a sound similar to a whistle. 

6.7.2 If a leak is detected: Check the tightness of the wing nuts securing the filter cassette to 

the sampler. 

6.73 Inspect the manometer flexible tubing for crimps or cracks. 

6.7.4 Open the manometer valves fully and blow gently through the tubing, watching for the 

free flow of the fluid. 

6.75 Adjust the manometer sliding scale so that the zero line is at the bottom of the meniscus 

fluid. 

6.7.6 Connect the manometer to the pressure port on the orifice. 

6.7.7 Ensure that the tubing fits snugly on the pressure port and on the manometer. 

6.8 Turn on the sampler and allow it to warm up to operating temperature (15-30 minutes). 

NOTE: The Quick Reference for the HIGH VOL+ Control Module Audit Set-Up Instructions

(Attachment B) explains how to operate the sampler and record all information.

6.10 Set-up the audit faceplate and orifice with vacuum line tee-off to the orifice, to the water 

manometer, and to the AutoCal port on the control box. 

6.11 Ensure that the sampler is operating in ambient conditions once the sampler has warmed up to 

operating temperature. 

6.12 Record the pressure drop across the orifice, recording both sides of the water manometer 

deflection, and record the PCal reading from the control box display onto the audit datasheet. 

6.13 Verify that the correct readings have been inscribed on the data sheet. 

6.14 Determine the ambient flow rate through the audit orifice, as follows: 

Qa (audit) = {sqrt[dH20*(Ta/Pa)]-b} {/m} 

Where 

Qa (audit) = actual flow rate as indicated by the audit orifice transfer standard 

dH20 = pressure drop across the orifice, inches H20 

Ta = ambient temperature, °K (°K = C° + 273) 

Pa = ambient barometric pressure, mm Hg 

b = intercept of the audit orifice transfer standard's calibration relationship 

m = slope of the audit orifice transfer standard's calibration relationship 

6.15 Calculate the percentage difference between the sampler's indicated flow rate, Qa(sampler) with 

the orifice installed, and the corresponding audit flow rate, Qa(audit), determined from the audit 

orifice transfer standard as: 

 Audit flow rate % difference = [Qa(sampler) – Qa(audit)] / Qa(audit)} {100} 

6.16 Record the audit flow rate percentage difference on the data sheet. There are 3 possible 

outcomes: 

6.16.1 If the audit flow rate percentage difference is less than or equal to ± 7%: The 

sampler calibration is acceptable and the sampler has passed the audit. 

6.16.2 If the percentage difference lies between ±7% and ±10%: A note is included on the 

audit field sheet that indicates the sampler has passed the audit but has triggered the 

ADEQ Air Monitoring Unit’s internal action level for service.

6.16.3 If the percent difference exceeds ±10%: The sampler has failed the audit and this 

triggers a corrective action response. If an AMU technician is present at the time of the 

audit, they may service the sampler to correct any problem and prevent the potential 

of loss data. Complete a corrective action notice and route through to the designated 

Air Monitoring Unit staff so that the failure is documented.

NOTE: The sampler's calibration, audit orifice standard’s certification, and all calculations 

must be double-checked before finalizing the audit. Upon a failed audit, an immediate 

re-audit may be conducted to verify the initial results. 

6.17 Remove all equipment and place sampler back to sampling mode once the audit has been 

performed. 

6.18 Document the visit and service performed in the sampler’s Instrument Logbook. 

6.19 Complete the Site Log Book form.

 All flow calculations are in Actual Conditions - Temperature and Pressure are Actual Ambient Conditions

For calculation of audit orifice flow rates:

Ambient Calculation Formula: Qa (audit) = {sqrt (H20 * (Ta/Pa)) - b} / m

Standard Calculation Formula: Qstd = 1/m [Sqrt ("H2O (Pa/Pstd) (Tstd/Ta)) - b]

CFM % difference formula: % Difference = (set point cfm - Qamb cfm ) / (Qamb cfm)) * 100

Quick reference for the TISCH TSP HIGH VOL + Control Module Audit set-up 

 Record the sampler’s date and time setting on the control module – main screen. 

 Press the set-up <F3> pad. 

 Move the arrow curser down to the Diagnostic pad and Press Enter – from here you will be 

able to find and record the Temperature and Barometric Pressure reading from the audit 

device being used and compare it to the samplers reading. 

 Move the arrow curser down to the Filter Saver and Press Enter – this will open the filter cover 

this will allow you to remove the sample filter cassette and install the audit filter and orifice. DO 

NOT TOUCH THE FILTER MATERIAL. 

 Scroll the arrow curser to Motor Control and Press Enter. 

 Scroll the curser down to Qsys and Press Enter. 

 Select the AMB and Press Enter – the sampler will start up and adjust to the calibrated flow 

setting. A 30 minute warm up is required. 

 Record water manometer reading and the control box CFM reading once the sampler has 

warmed up; enter both readings on the audit form. 

 Press the ESC pad key to exit out. 

 Go back to the Diagnostic screen and select the Filter Saver once the audit equipment has 

been removed and the sampler’s filter has been re-installed. 

 Press Enter to close the cover. 

 Press ESC to return to the main screen.
