Non-Fatal Errors
Non-fatal errors can be programmed to scroll during the one second display off-time or lock
on the meter display. If multiple non-fatal errors occur, the meter will display a combined
error message. For example, if a Low Battery error and a Time of Use error exist, the error
display will read
Err 1-3---
. In this case, if one of the errors had been programmed to
lock, and the other error had been programmed to scroll, the display will lock on the
combined error message.
Selecting a display mode by holding the magnet near the cover’s magnet icon at the nine
o’clock position allows that display mode sequence to scroll one time during a locked non-
fatal error. At the end of the display sequence, the error message locks onto the display
again.
For non-fatal errors, transmission can be controlled via PC-PRO+ Advanced software.
Non-Fatal Errors
Error Code Error Possible Cause(s) Error Description
Err 1----- Low Battery
Error Battery Voltage
Low.
Battery Not
Connected
Properly.
A low battery check is
performed once a day and upon
a set clock procedure. A low
battery continues to function;
however, its reliability
decreases over time. As long as
the meter is not powered down
with a dead or missing battery,
the meter will continue to
function as normal.
If the meter is powered down
with a dead or missing battery,
then, when power is restored,
the meter's clock will be off by
the duration of the outage, and
Load Profile and TOU will be
halted.
Err --3--- Time-of-Use
(TOU) Error

Current Season
is not
programmed.

Current Year is
not
programmed.

TOU halted due
to power down
with dead or
missing battery.
This is tested at power-up, at
midnight crossings, at season
changes, upon reconfigures
and upon set clocks.
Depending on the cause of the
error, it can be cleared with a
corrective reconfigure or with a
set clock with a good battery
present.
