Troubleshooting Guide
The Class 4000 electronic kilowatt-hour meter is caibrated and tested at the factory be-
fore being packaged and shipped. If installed properly and in accordance with the instal-
lation instructions, the Class 4000 meter will provide years of trouble-free service. If the
meter should not function, the following guide will assist in troubleshooting the instal-
lation. If, after following the procedures below, the meter still does not function, please
call E-Mon’s technical department at (800) 334-3666 BEFORE removing the meter.
PROBLEM
PROCEDURE TO FOLLOW
1. Display reads all ZEROs, or
is not incrementing.
.
A. Determine if the load is sufficient to update the
display. (A load of less than 1% of the meter rating
may require more than 24 hours to change the
display reading.)
B. Check the current sensors for installation.
C. Be sure that the current and voltage inputs have
proper phase relationship.
D. Check wiring to voltage terminals.
E. Check circuit breaker or fuses.
F. Test source for correct voltage.
2. Display reads only a fraction
A. Check the supply voltage to be sure that it is on

continuously 24 hours a day.
B. Check the current sensors for installation and
polarity.
C. Check the sensor wiring to the terminal block in
the meter (color coding white to white and black to
black).
