· Verify voltage leads are properly connected.

Reported power too low

· Verify CTs and terminals are color-matched.
· Check for phase loss.
· Check external fuses.

Reported power inaccurate

Verify meter and CTs have matching serial numbers (serial number matching does not apply if using

100 A CTs).

Accuracy not as specified

· Verify CTs and terminals are color-matched.
· Verify that no stray conductive materials (wire clippings, etc.) have shorted between the terminals.

No Pulse output (H8163 and H8167)

· Verify power is supplied in the range of 5-24 VAC/DC, with a max. load of 100 mA.
· The pulse output internal is 200 msec; verify the controller accepts this signal as input.

Pulse output wrong, display OK (H8163

and H8167)

Set the pulse rate switch and the controller to match kWh/pulse.
