LED Indicators Description
Power LED (green) Illuminates when the meter is supplied with proper voltage
Load LED (green) 50% duty cycle (at constant load) LED to verify proper
meter function when connected to a load. At 200 watts,
LED will illuminate for 1.5 minutes, then turn off for 1.5
minutes; with no load, LED will remain on or off
Reverse Phase LED (red) Illuminates when a problem with meter phasing exists.
