Meter Self-Test
Each time that power is applied to the EPM 5100, it performs a self-test of its internal
electronics. If there are no problems, the EPM 5100 displays the following message before
entering into Metering mode:
If a critical failure is detected at self-test, the following message appears on the display:

failure message reappears, contact GE Multilin technical support.
