8.9.2.1 CA 000 001—Low Battery
The Low Battery caution indicates a weak or missing battery. The meter periodically tests the
battery. The meter sets the Low Battery caution if the battery voltage is low. The Low Battery
caution is cleared when the battery test passes. The meter tests the battery under the following
conditions:
• Power up
• 1st of each month (00:16)
• Activation of the Display Switch (not in Test Mode)
• MeterMate Meter Communication command
8.9.2.2 CA 000 010—Un-programmed
The Un-programmed caution indicates that the meter is not programmed and is functioning in a
default demand mode. The meter is shipped un-programmed unless it is ordered factory-

back to the default demand program and operate from it. If a meter has an Un-programmed
and Loss of Program caution, reprogram the meter and the Un-programmed and Loss of
Program caution will be cleared.
8.9.2.5 CA 000 400—Low Potential
The Low Potential caution indicates that measured voltage falls below the programmed
tolerance. The voltage is tested every five seconds using the voltage from the previous second.
The meter sets the Low Potential caution when the test fails three consecutive times. The
