Understanding Charging Status LED Indicators
The charge status indicated by the green LED behind the Power button is as
follows:
• Solid green: Charging
• No green light: Not charging
• Green light wink: Maintaining charge
• Green light fast blink (two times per second): Charger fault
• Green light fastest blink (three times per second): Meter is powering
up or shutting down
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 (Tools
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.
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.
