Error Description
Err 1-----
Low Battery Error
Battery Voltage Low
Battery Connector Not
Connected Properly
Connected Properly
A low battery check is performed once a day and upon
initialization. If a low battery level is detected during this
procedure, the error code can be displayed in Normal Mode.
This error can be programmed to continuously scroll during the
display off time or lock on the meter display. A low battery
continues to function; however, its reliability decreases over
time.

procedure, the error code can be displayed in Normal Mode.
This error can be programmed to continuously scroll during the
display off time or lock on the meter display. A low battery
continues to function; however, its reliability decreases over
time.
If a dead battery is detected upon restoration of power, the error
code will display until the battery is replaced. TOU and load
profile functions will be disabled until the battery is replaced and
the time is set. Total registers remain functional during a dead
battery condition. However, TOU (rates A, B, C, D, E, F, G)
registers and Load Profile Channels will not accumulate after
an outage with a dead battery. If a dead battery level error
occurs during normal operation, TOU and load profile will
continue to operate until an outage occurs.

Reverse Direction
Error
Error
Reverse Power was
detected on one or

detected on one or
more phases.
A Reverse Direction error exists when the meter detects one
second of (Active) energy on one or more phases in the reverse
direction. This error is applicable to kWh only. Reverse direction
detection is a selected feature during programming. This error
is reported only when the meter is not measuring kWh received
and/or kWh net.

Clock/Load Profile
Error
Error
This error occurs if the meter is powered up with a dead or no
battery when it is configured for load profile. If this error occurs,
the error code is displayed in Normal Mode. If a Clock/Load
Profile error occurs, the load profile and TOU operations will be
discontinued until the meter is reprogrammed. The error will
then clear and the meter will resume normal operation.
