4~20mA Analog Output Calibration
Note
Each flowmeter has been calibrated strictly before leaving factory. It is unnecessary to carry
through this step except when the current value (detected while calibrating the current loop)
displayed in Window M58 is not identical with the actual output current value.
The hardware detect window must be activated prior to calibration the Analog Output. The procedure is as
follows:
Press
enter password "115800", then press
to activate the detect menu. With no effect to
next power on, this window will close automatically as soon as the power is turned off.
Press
to calibrate the current loop 20mA output. Use an ammeter to measure the current loop output current.
At the same time, press
or
to adjust the displayed numbers. Watch the ammeter until it reads 20.00.
Stop at this point, the 20mA has been calibrated.
Then, press
to calibrate the current loop 4mA output. The method is the same as 20mA calibration.
The results are automatically saved in EEPROM and won
’
t lose when power off.

ESN
We provide the Flowmeter with a unique electronic serial number to identify each Flowmeter for the convenience
of the manufacturer and customers. The ESN is able to be viewed in Window M61.
