5. Troubleshooting/FAQ
Problem
Solution
1. Power LED not illuminated
 Check to make sure all connections are
wired
 Test the voltage being supplied to the
meter using an AC voltmeter
 With power off, remove any additional
line fuses and test with ohmmeter
2. Load LED not flashing
 Verify CT connections and orientations
 Make sure there is sufficient load to
draw a significant current
 Test the voltage being supplied to the
meter using an AC voltmeter
3. Registered consumption low
 Check to make sure the reverse phase
LED is not on
 Even if the reverse phase light is off,
double-check CT orientations. One CT
installed in the incorrect direction
doesn’t always illuminate the reverse
phase LED
 Make sure that current and voltage
connections are in phase
 Check power connections and fuses
4. Reverse phase LED illuminated
 Verify orientation and connection of CT
wires
 Ensure that phasing is correct (CT1 on
Line 1, CT2 on Line 2)
 Verify that a load drawing more than 1
Amp is connected to the meter
