64 +This device uses one-point calibration, and you need to prepare a known E standard solution. When mileage K=1, 1~~2000 uses 1413uS/cm standard solution, and when mileage K=10, 10~~20000 uses 12.88mS/cm standard solution. The calibration steps are as follows:
65 +(1) Place the electrode in distilled water and clean it. When mileage 1~~2000 uses 1413HS/cm standard solution, enter the following calibration command after the data is stable.
