5 TROUBLESHOOTING / FAQ
Problem
1. LCD Display not on
2. Load LED not flashing
3. Registered consumption low
4. Reverse phase LED illuminated
Solution
• 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 in-line
fuses and test the circuit with the appropriate test
equipment
• 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
• 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
• 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
