EC 1.41
Note: Shake the sensor gently,making sure the sensor immersed completely.
After the EC sensor has been used for a period of time, it needs to be decontaminated and
calibrated regularly.
The way of maintenance: take out the sensor, d the impurities on the suace with a soft cloth,
and make the suace smooth again. According to the dierent water quality and production
environment in dierent regions, it should be maintained eve 15 days or 30 days; if there is a big
dierence between the reading and the expected value, the user can individually correct the coe-
cient of the EC sensor.
EC Sensor Calibration
Press and hold the "EC (0)" button "Calibration" button to enter the EC sensor calibration state,
put the cleaned EC sensor in the air, wait for the calibration of the device to end, the duration is 25
seconds, and the screen displays a 25-second countdown—calibration After completion, it
automatically enters the stage of correcting EC1.41.
Put the cleaned EC sensor in the standard solution of EC1.41, and wait for the calibration of
the equipment to end, which lasts for 25 seconds - after the calibration is completed, the current
value should display 1.41.
