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 (

).
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.

following external power sources:
•
USB port from a computer
