5.2 Analog Output Calibration
To check the 4-20 mA circuit, connect a DVM in series with the output loop. Select zero or full scale (from the second
column of the hidden diagnostics) and then press the
ENTER
key twice. This action will cause the meter to output its
4 mA or 20 mA signal. If the DVM indicates a current variation greater than ± 0.006 mA from the 4 mA or 20 mA
signal, adjust the setting up or down until the output is calibrated.
Note: These settings are not for adjusting the output zero and span values to match a flow range. That function is
located in the Output Menu.
