5.0 Getting Started

5.1 Initial Operation

Select a location that is dry and not subject to drafts or moving air from heating or air conditioning 

vents, or air blown by other equipment. Place the unit on a flat, preferably non-flammable surface. 

Allow sufficient room around the unit for access and cooling. Six inches minimum on all sides is 

suggested. Plug the unit into a properly grounded outlet. Using the lifter, insert the block(s) into the 

well. The unit is now ready for use.
 Instruction Manual | 3

5.2 Controls

 ON/OFF rocker switch – located on back of unit. Turns primary power on and off

 Start/Stop LED, red – used to activate or stop the unit. Illuminates when unit is in heating mode, off in 

temperature set mode

 Heating LED, red – illuminates when unit is in heating mode and unit is actually apply heat to the block. 

This LED is on continuously during heat-up and cycles and off when the unit is at set temperature.

 Time LED, green – used to set or select time mode. This LED light indicates running Time Mode.

 TEMP-UP arrow key – raises set temperature when unit is in set mode.

 TEMP-DOWN arrow key – lowers set temperature when unit is in set mode

 Timer-UP arrow key – raises set time when unit is in set mode.

 Timer-DOWN arrow key – lowers set-time when unit is in set mode. To enter continuous mode, set the 

time to 00:00, hold the Timer-DOWN arrow key while pressing the

 Start/Stop key – unit will display “Hold”

6.0 Operation

1. Place Labnet Dry Bath Incubator on a sturdy and level surface in a safe, dry place, away from 

laboratory traffic.

2. Ensure that the AC power switch is OFF, then plug the three-pronged power cord into a grounded 

three-prong AC outlet of the appropriate voltage (115V or 220V as indicated on the rating sticker 

near the AC cord on the back of the unit).

3. Select suitable module block(s) or appropriate water volume and put it/them into the Labnet Dry 

Bath Incubator

4. Turn the AC power ON.

5. Run temperature calibration procedure when using the instrument for the first time.

6. Press ▼ or ▲ key to adjust to the desired temperature.

7. Press ▼ or ▲ key to adjust to the desired timer.

8. Press Start/Stop key to start heating.

9. If to reset timer is required during heating, press Start/Stop key to deactivate heating.

10. Press Start/Stop key again to stop the unit.

11. If lid is to be used, aim the shaded area on the dry bath surface with the magnet of the lid and it will 

be attached to the housing. In order to remove the lid, press one hand firmly on the housing with 

another hand pulling the lid off. To use the lid, the tube should not be exceeding 25 mm than the 

heating block.

7.0 Calibration

Calibration allows the unit temperature display to be adjusted or matched to the temperature of a single 

sample or to a calibrated thermometer making an independent temperature measure of the block. 

The Digital Dry Baths are calibrated at the factory at 37, 60, 90, 120, 140°C using a standard 20 x 13 mm 

heating block. If you are using a block with a high heat loss rate such as a block with large holes or a 

platform style block, you may choose to recalibrate the unit to your specific application. Also, if you 

are using very loose or odd shaped vessels, the calibration function can help you match the display 

temperature to your actual sample temperature. 

To calibrate the unit for a given block or sample, first turn the unit off using the ON/OFF switch. Then 

place a thermometer of known accuracy* into the block thermometer hole or a thermocouple or other 

sensor into your sample. Make sure there is a good fit between the thermometer and the block or good 

contact between any sensor and sample or sensor and block.

To calibrate the block or sample to the display, use the following procedure:

1. Press and hold the Start/Stop key then simultaneously power up the unit with the ON/OFF switch.

2. You should hear a “DU-DU-DU.” sound from the dry bath and the display will have one segment 

flashing on the left and will show a set temperature, and the right will show adjt.

3. Use the UP and DOWN arrow keys to set the desired temperature at which you want to calibrate the 

unit. Then press the Start key.

4. Allow time (up to 10 or 20 minutes) for the unit to heat up to your set temperature and to equilibrate 

at this emperature. The entire LED display will start flashing when equilibration is reached.

5. After the entire display has started slashing, red the thermometer (or sensormeter) and use the UP 

and DOWN arrow keys to adjust the display to the thermometer or sensor reading then press the 

Start/Stop key.

6. The unit will then begin to automatically adjust its operating temperature to your original set point 

with the re-calibration factor included. Allow sufficient time for the unit to reequilibrate and then 

again compare the thermometer or sensor reading to the calibrated display. They should closely 

match. If not, repeat the calibration procedure.

*Thermometers used for calibration purposes should have a written calibration certificate and be 

traceable back to NIST or some other certified body. General lab thermometers are often not accurate 

enough for calibration work.

8.0 USB Interface

The Digital Dry Baths have a USB unidirectional data port. A software and cable are available which 

allow a user to use a desk top or lap top computer to record and/or print a record or the temperature 

profile produced by the dry bath.

Should you have a question about the operation of the Labnet Digital Dry Bath or if service is required, 

contact Customer Service. Do not send in a unit for service without first calling to obtain a repair 

authorization number. Should the unit require return for service, it should be properly packed to avoid 

damage. Any damage resulting from improper packaging shall be the responsibility of the user.

10.0 Cleaning and Maintenance

Make sure that the dry bath and block are cool and the power cord is disconnected before performing 

any cleaning or maintenance. Repair or maintenance should only be performed by an authorized service 

technician. 

The dry bath may be cleaned with a moist cloth containing a mild soap solution. Do not immerse the 

dry bath in water or any liquid. The blocks may also be cleaned in a mild soapy solution. Be sure that all 

items have thoroughly dried before attempting to connect the cord or use the unit. 

Spills: In the event liquid is accidentally spilled into the bath or well area, disconnect the plug from the 

outlet and turn the unit upside down to minimize liquid contact with the internal components. Remove 

the bottom cover and inspect to assure liquid has not contacted heater elements, electronic controls, or 

connectors. Have qualified service technician clean the unit and replace any damaged parts.
