Precautions for Measurements
Air Velocity●MODEL6531/6541/6561: The probe has its own
directivity characteristics. Make sure that thedirection mark is facing into the airflow. If you
are not sure of the airflow direction, slowly rotate
the probe and select the point where you get the
maximum velocity reading.

Direction Mark

Airflow●MODEL6533/6542/6543/6551/6552: This omnidirectional
probe has a horizontal, 360 degree dynamic characteristic(Refer to “Directivity of the Probe” on P.57 for details).
●The probe relies on both an air velocity sensor and temperaturecompensation sensor to accurately measure air velocity. In orderto do so, it is necessary that both sensors are evenly exposed to the
airflow under the same temperature conditions (Refer to the figuresof the probes on P.9 for the location of the sensors).
●For measurements in an environment with rapid air temperaturechanges, measure for at least 20 seconds and wait for the reading tostabilize before starting the actual measurement (i.e. the data will
not be accurate until the probe has time to acclimate to theenvironment.)

Air Temperature●The faster the wind, the shorter the response time for temperature
measurements. The normal response time is approximately 30
seconds when the air velocity is 1 m/s (90% response). Wait for thereading to become stable before taking a measurement.
●When no airflow is present, the air temperature reading may behigher than the actual temperature due to the heat generated by the
air velocity sensor. It is recommended that you SLOWLY wave theprobe to create an environment with approx. 0.1m/s airflow to
obtain accurate temperature readings.

Humidity*For more
information on proper
handling of the
ASSMAN
Psychrometer, pleaserefer to JapaneseIndustrial Standard(JIS-Z8806 “Methodof measuring
Humidity), or its
counterpart standards
that apply.

14●Humidity readings in an atmosphere with extremely high humidity
or rapid temperature changes may be higher than the actual
humidity due to condensation generated on the surface of the sensor.
If this occurs, allow the probe to dry in an atmosphere with 40%RH
humidity or less for 24 hours.
―― Comparing with ASSMANN Psychrometer ――
The humidity measurement function of CLIMOMASTER is strictly
calibrated, traceable to Japanese National Standards carried by JEMIC(Japan Electric Meters Inspection Corporation), and it assures you highly
accurate performance.
The electronic hygrometer, used in CLIMOMASTER, is known to be morestable and has a shorter response time compared to conventional
ASSMAN Psychrometers. Also, the electronic hygrometer is not dependent
upon the measurement conditions, while an ASSMANN Psychrometer caneasily be influenced by many factors such as dust, condensation and theway the gauze is wrapped.

Getting Started

Pressure■ Pressure sensor isonly available on
MODEL6501-B0/-C0.

●Do not expose the pressure sensor to more than 75kPa of pressure.
Excess pressure may cause serious damage to the sensor.
●The operating temperature must be between 5oC and 40oC or 41oF
and 104oF when measuring pressure. The instrument may not
operate properly outside of this temperature range.
●Make sure to perform a zero adjustment before measuring
pressure. When performing a zero adjustment, leave both pressure
ports (+) and (-) open.
●The zero adjustment range is – 0.5 to 0.5 kPa. If the reading is outof this range, an error message will be displayed.

FLOW measurements in Normal Mode. If you need to apply the time
constant to the AIR TEMPERATURE, HUMIDITY and PRESSURE
measurements in Normal Mode, refer to the next section “Changing
Time Constant Application”.

*** What is Time Constant? ***Time Constant determines the time span of the moving average. When you set the Time
Constant to a larger (longer) value, the readings will become stable. When you select a smaller(shorter) value, the readings will become more responsive and sensitive to changes in air
velocity. This function is not available in Calculation or Flow Rate Mode.

Measuring Max, Min, and Mean: CALCULATION Mode§5Measurement of Air Flow

FLOW RATE Mode

CLIMOMASTER features an accurate Flow Rate Mode whichcorresponds to the industry measurement standards such as
ASHRAE.

SINGLE FLOW RATE Mode
This mode is useful for performing a measurement of the airflow ofduct (i.e. a duct traverse). Following the steps listed below, you
can program Climomaster with the following parameters:

Sampling Time: The instrument will take a sample at the endof this entered sampling time. Example: if you setup asampling time of 10 seconds, Climomaster will wait 10
seconds and then take a measurement. If you are taking
multiple samples, it will wait 10 seconds between each one
before taking the next sample.
Number of Trials: this is the number of samples you wish tocollect from a single point in the traverse.
Number of Points: this is the total number of points in thetraverse.

In single mode, the average, maximum and minimum values fromall points will be calculated. The instrument will record the average
from each point as well as providing a final average of all the points
in the traverse.
Value at point 1
POINT(1)
TRIAL(1)(2)(3) ……(N)Value at point 2
POINT(2)
TRIAL(1)(2)………………

(3) ……(N)Value at point M
POINT(M)

TRIAL(1)(2)(3) ……(N)Time needed to measure a point…Sampling Time X N (Number of Trial)

The value of each point isrecorded as the average of
TRIAL(1) to TRIAL(N). This value(for each individual point) is stored
in the memory.

POINT(1): avg(1)＝ΣTRIAL(N)／N
POINT(2): avg(2)＝ΣTRIAL(N)／N・・・
POINT(M): avg(M)＝ΣTRIAL(N)／N<Result> Average (AVG): AVG＝(avg(1)+ avg(2)+ ････+avg(M))／M
 Maximum (MAX): MAX＝ Maximum value from avg(1) to avg(M).
 Minimum (MIN): MIN＝ Minimum value from avg(1) to avg(M).
To take an accurate measurement of the airflow of duct, you need to figureout the average velocity of air inside the duct and the area of the crosssection of the duct.

MULTI FLOW RATE is very similar to the SINGLE FLOW RATE MODE,
except it adds an additional parameter for the number of locations.
This allows you to take several air flow measurements (i.e.
traverses) and get a total average, for example measuring flow ratefrom multiple ducts to get an overall average.
The value of each point is theaverage of TRIAL(1) to TRIAL(N).
The value of each location is theaverage of POINT(1) to
POINT(M). The value of eachlocation will be stored in thememory.

How to Clean a Probe
Dust or particles attached to the velocity sensor would alter theamount of heat diffusion, which leads to a less precise reading. Also,
deformation or clogging of the protective mesh around the sensor of
the probe would also affect the accuracy of the instrument.
Users are encouraged to clean the probe regularly to maintain theaccuracy of measurements.
Procedure
Clean the sensor by soaking it in water in an ultrasonic cleaner for 10
to 20 seconds. Do not soak it for too long, since there is anincreased risk of damaging the coating.
Please use only water for cleaning the probe.

︕CAUTION︕!)!)!)

When cleaning, make sure that the power is turned OFF.
Make sure that the sensor is dry before turning it ON.
DO NOT let the humidity sensor come into contact with water(MODEL6531/6533). When wet, let it air dry by placing it in anenvironment with less than 40%RH for more than 24 hours.
!) NEVER USE alcohol or any other organic fluid.
Alcohol will cause permanent damage to the humidity sensor.
Once the sensor is damaged, it will need to be replaced even if it
seems to be functioning.
DO NOT place the sensor in an
upward position until it iscompletely dry as residual water
could damage the sensor.

Current

The principle of the thermal Probe isbased on a heated element from whichheat is extracted by the colder impact
flow. The temperature is kept
constant via a regulating switch. The
controlling current is directly
proportional to the velocity. When
Velocity m/s thermal velocity Probes are used inturbulent flows, the measured result is
influenced by the flows impacting theheated body from all directions.
In turbulent flows, a thermal velocity sensor indicateshigher measured values than a vane Probe. This can beobserved during measurements in ducts. Depending on
the design of the duct, turbulent flows can occur even at
low velocities.
The amount of heat that is extracted by
the colder impact flow from the sensor can be expressedby:H  (a  b U )(T  Ta ) ・・・・・・King ' s fomula

Velocity [U]Also, heat diffusion quantity can be expressed by theformula:H  RI 2
Where R is resistance and I is current(R is kept constant regardless of air velocity since thetemperature in constant).
Therefore,

RI 2  a  b U
The Temperature Compensation
The air velocity sonsor is heated to an elevated temperature
relative to the surrounding air by means of control
electronics. The temperature compensation sensor senses
the ambient, or surrounding air temperature and forces thevelocity sensor to stay at a constant overheat above theambient. The circuit forces the voltage to be equal bymeans of an operational amplifier. Air flowing past thesensor tends to cool the sensor, thus driving down its
resistance.
The amplifier responds by immediately
delivering more power to the circuit to maintain voltage
equilibrium.
Delivered power is converted into anelectrical signal to display.

Temp Sensor(Platinum Resistor)

Measurement of Wind-Temperature(MODEL 6531/6541/6542/6533/6543/6561)
The coefficient of resistance of the temperature sensor has adirect proportional relationship with the temperature. We canmeasure the wind temperature by adjusting the sensor’s
temperature to the wind-temperature, and measuring its
coefficient of resistance.

Measurement of Humidity (Hygrometer)(MODEL6531/6533)
The sensor is a pair of condensers and its
Upperelectro-capacity is dependent upon the amount ofElectrodewater contained in its hydrophilic macromolecule

membrane and an upper electrode.
The upper electrode will capture the change in
Glasspermittivity caused by condensation orFoundation
evaporation of water vapors to the macromolecule
membrane. (Electrostatic Capacity Type)
There is another type of hygrometer that uses a resistor instead of a condenser.
Typically Electrostatic Capacity types are good for low humidity measurements and theresistor types are good for high humidity measurements.
Theory of detecting static pressure (MODEL6501-B0/6501-C0)
To measure static pressure, we use a diffusion-type semiconductor pressure sensor.
The diffusion-type semiconductor pressure sensor is incorporated under the principlethat the resonant frequency of a piezo-crystal decreases linearly with the pressure
applied. On a thin diaphragm of silicon, there are four diffusion resistors (sensor chips)
placed in a fixed distant apart. (Pic.1)
When the pressure is applied from above, the diaphragm will deflect downward. When
it is deflected, the sensors near the center (R3 and R4) will have compressing stress andthe sensors near the perimeter (R1 and R2) will have tensile stress instead. (Pic.2) The
diffusion coefficient of the diffusion resistor changes according to these two stresses.

About Compensation
This instrument has been calibrated at normal temperature andpressure. Therefore, if you are going to measure velocity at adifferent temperature and pressure, the indicating value will beaffected.
Influence of Measuring TemperatureThis instrument has been calibrated at normal temperature.
Because of theoretical fundamentals of hot-wire anemometers, it
can easily be effected by the ambient temperature. To prevent
such influence, temperature compensation is needed.
The
temperature compensation sensor senses the ambient, or
surrounding air temperature and forces the velocity sensor to stayat a constant overheat above the ambient temperature.
Byadopting temperature compensation sensors, you can measure air
velocity accurately within a range of 5〜60 oC (41〜140oF)

Influence of Pressure at Measuring Point
The instrument is calibrated under atmospheric pressure of 1013
hPa. Since change in the atmospheric pressure will influence theheat dissipation amount, compensation of the atmospheric pressure
is required. Compensation can be provided by using the following
formula.

Um 

1013
 Uc
Pm

Where: Um: Actual Velocity[m/s]
Uc: Indicating Value
Pm: Atmospheric Pressure at the Measuring Point [hPa]

Measuring Gas Components
This instrument has been calibrated using normal air (i.e. 79%
nitrogen concentration & 21% oxygen concentration). If you wish
to use the instrument in an environment other than normal air, youwill need to compensate for the characteristics of the gas mixture
you’ll be using the instrument in.
