Do calibration procedure
The calibration procedure has one-point calibration or two-point calibration
One point calibration: (to meet normal use)
0.0% (oxygen free water) or 100.0% (air).
Two point calibration:
Simultaneous calibration of 0.0% (oxygen free water) and 100.0% (air)
The calibration of the instrument is simple. Make sure that the probe is installed correctly before calibration
100.0% - calibrate in the air after the value is stable in the power on state. Long press the cal key for 5 seconds and release the key. The screen flashes 100.0%. After flashing, the calibration is completed.
0.0% - calibrate in anaerobic water when the value is stable in the power on state. Long press the cal key for 5 seconds and release the key. The screen flashes 0.0%. After flashing, the calibration is completed.
