Resolving a “Charging Stopped” Session Log Entry
To resolve a “Charging Stopped” Session Log entry, check the battery
placement, and make sure the correct
Battery Type
is selected (

System Properties
).
Resolving an “Incorrect Battery Type” Session Log Entry
Infrequently, when the battery becomes too old to charge, the meter
may register the battery as the incorrect battery type. This can also
occur when newer NiMH batteries are fully discharged. In this case,
charge the batteries using an external battery charger, then install
them in the meter.
You may also see this error when the batteries become too hot or too
cold. Optimal battery temperature is 0° C–45° C.
3.5.2 Using External Power
We recommend maintaining the internal battery The 831C utilizes the
following external power sources:
• USB port from a computer
• USB port from PSA029 power supply
• I/O connector from an external +10.8 to +25 Volt DC mains
power source.
