5.0Calibration Procedure

5.1Humidity 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.

5.2T1 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.

5.3Notes 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.
