4mA-20mA Calibration
Before calibration, please connect ammeter in series with 4-20mA loop, current of flow rate will be
displayed in the ammeter. Press
long for 3s to enter 4mA calibration. If current displayed is not
4mA, press
to increase current or press
to decrease until the ammeter displays 4mA.
Each time you press, 0.016mA will be changed. After calibration, press
long for 3s to save
calibration; or press
SE T
SE T
to exit without saving calibration.
After calibrating 4mA, press
