The procedure for testing the Analog Input metering is shown below:
 Inject steady values of DC current (in mA) of various values into relay
terminals A1(+) and A2(–).
 Verify that the analog input is correctly measured and displayed in the
value.
I
 Inject a fixed rate of ramping DC current (in mA) of various values into
relay terminals A1(+) and A2(–) for at least 2 minutes.
 At the end of this time, verify that the analog input is correctly measured
and displayed in the
 Inject a fixed rate of ramping DC current (in mA) of various values into
relay terminals A1(+) and A2(–) for at least 2 hours.
