meter.
This step tests for compliance voltage problems, such as low power supply voltage or
increased wiring resistance.
RRM: Select Setup, Output from the menu.
Make sure Alarm Mode AOut 1 is set to High Current. Click Store to save changes. Click

4. Set Alarm mode to Low Current. Using loop test, enter the mA value representing the
low alarm current. Verify that the analog output current is correct using the reference
meter.
This step tests for possible quiescent current related failures.
RRM: Set Alarm Mode AOut 1 to Low Current. Click Store to save changes. Click Loop
