5.0 Calibration 
Procedure 
5.1 Humidity 
Calibration 
1. 
Turn the unit off. Press and hold the MAX MIN,  HOLD and REC buttons. While 
these three buttons are pressed, turn the power on. Release these buttons and all 
the segments on the display will flash. 
2. 
Within 3 seconds of releasing these buttons, press the °C/°F and TIME buttons 
simultaneously to enter the calibration mode, or the instrument will revert to the 
normal operating mode. 
3. 
Upon entering the calibration mode, the humidity reading will flash, and ‘CAL1’ will 
appear on the second display.   
4. 
Insert the humidity probe into the standard humidity cavity of 32.8% RH@25°C. 
Allow the system to stabilize for 20 minutes, and then press the MAX MIN button to 
create the calibration data. If the instrument recognizes the value is out of tolerance, 
it will sound 2 beeps and remain in the ‘CAL1’ mode. If the instrument recognizes 
the value is within tolerance, new calibration data is created and the instrument will 
advance into the ‘CAL2’ mode, as indicated on the second display. 
5. 
Insert the humidity probe into the standard humidity cavity of 75.3% RH@25°C. 
Again allow the system to stabilize for 20 minutes, and then press the MAX MIN 
button to create the calibration data. If the instrument recognizes the value is out of 
tolerance, it will sound 2 beeps and remain in the ‘CAL2’ mode. If the instrument 
recognizes the value is within tolerance, new calibration data will be written into the 
memory and the calibration is complete. 
5.2   T1 Temperature Calibration 
1. 
Turn the unit off. Press and hold the MAX MIN,  HOLD and REC buttons. While 
these three buttons are pressed, turn the power on. Release these buttons and all 
the segments on the display will flash. 
2. 
Within 3 seconds of releasing these buttons, press the °C/°F and HOLD buttons 
simultaneously to enter the calibration mode, or the instrument will revert to normal 
operating mode. 
3. 
Upon entering the calibration mode, the temperature reading will flash and ‘CAL1’ 
will appear on the second display.   
4. 
Insert the probe into a temperature-controlled chamber at 0°C (32°F) and allow the 
system to stabilize for 20 minutes. Press the MAX MIN button to create the 
calibration data. If the instrument recognizes the value is out of tolerance, it will 
sound 2 beeps and remain in the ‘CAL1’ mode. If the instrument recognizes the 
value is within tolerance, new calibration data is created and the instrument will 
advance into the ‘CAL2’ mode, as indicated on the second display. 
5. 
Insert the probe into a temperature-controlled chamber at 40°C (104°F) and again 
allow the system to stabilize for 20 minutes. Press the MAX MIN button to create 
the calibration data. If the instrument recognizes the value is out of tolerance, it will 
sound 2 beeps and remain in the ‘CAL2’ mode. If the instrument recognizes the 
value is within tolerance, new calibration data will be written into the memory and 
the calibration is complete.

5.3  Notes on Humidity and Temperature Calibrations 
1. 
While performing the humidity calibration, the environment should be maintained at 
stable conditions (i.e. constant temperature and constant humidity) to optimize the 
accuracy. 
2.  During either calibration, pressing the   button at any time will return the 
instrument to the normal operating mode, and no calibration data will be changed. 
3.  To restore factory default calibration values, press the HOLD and REC buttons 
simultaneously at any time while in the calibration mode. 
4.  Whenever the probe is inserted into a standard humidity cavity or 
temperature-controlled chamber, always allow at least 20 minutes to ensure 
ambient conditions have stabilized. 
5. 
Always begin the humidity calibration process with the 32.8% RH@25°C standard 
cavity and the temperature calibration process with the 0°C (32°F) 
temperature-controlled chamber. For maximum efficiency, insert the probe into the 
conditioned environment 20 minutes before applying power to the instrument and 
starting the calibration process. 
6.  During the calibration, all displayed readings are based on pre-process    
calibration data. 
7. 
The ‘Auto Power Off’ function is disabled during calibration, but is automatically 
restored upon completion. 
8.  During the calibration, the temperature is fixed on the °F scale and it is    
not selectable.
