- After long hours of work, the sensor can become contaminated and the electronic parameters can deviate. If the reading
value is out of range, you must follow these steps to calibrate it.
1. Purchase standard salt bottles of 33% and 75% humidity.
2.
Please deactivate the auto power off mode and switch on the device as indicated in point 11 of the
previous section.
3.
Remove the protective cap and press the HOLD and ON/OFF buttons simultaneously. "---" will appear
on the LCD screen and "1" will appear on the right side of the screen. Place the device in the standard 33% humidity bottle
for 40 minutes. After 40 minutes, the unit will automatically adjust to the 33% value. Calibration work will end when
performed with two values. After calibration with 33%, perform the same procedure with 75%. If calibration is only
performed with the 33% bottle, turn the unit off manually and then on again to repeat the process once the error message
"Er2" disappears. After the two calibrations, the device will function correctly.
