4. Insert the probe into standard chamber of 0°C(32°F) and wait the system to stabilize for 20
minutes. Press MAX/MIN button to create the calibration data. If the tester recognizes the data
is within the tolerance, it will go to “CAL2” mode or it will sound 2 beeps and remain at “CAL1”
mode.
5. Insert the probe into standard chamber of 40°C(104°F) and wait the system to stabilize for 20
minutes. Press MAX/MIN button to create the calibration data. If the tester recognizes the data
is within the tolerance, it will write the calibration data into the memory and leave the calibration
mode. If the tester recognizes the calibration data is out of tolerance it will beep 2 times and
remain at “CAL2” mode.
Remarks:
1. After the probe is in the calibration cavity, wait at least 20 minutes to stabilize the system.
2. During the calibration, the user can leave the process by pressing the
POWER button at any
time and the calibration data will be kept unchanged.
3. During the calibration mode, the user can restore the factory default value by press the HOLD
and °C buttons at the same time.
4. Because it take some time to stabilize the system, we recommend the operator first insert the
probe into the 0°C standard cavity and wait for at least 20 minutes, then power the unit on and
start the calibration process.
5. During the calibration, all the displayed reading is calibrated with the old calibration data and
the auto power function is disabled. Until the calibration process is done, the tester will enable
auto power function again.
6. During the calibration, the temperature scale is fixed at °F and it is not selectable.
