Resetting the Battery Gauge
The accuracy of the battery gauge may drift over time if
the battery is frequently recharged before being fully
discharged.
To reset the battery gauge:
1 Completely discharge the battery until the tester no
longer operates.
Note
To shorten the discharge time for the remote’s
battery, swap it with the battery on the main
tester. The battery discharges faster on the main
tester.
2 Charge the battery for at least 4 hours with the unit
turned off.
3 Repeat steps 1 and 2.
Replacing the Battery
Replace the lithium ion battery pack when its life becomes
noticeably shorter or when it fails to reach full charge.
The battery is normally good for up to 400
charge/discharge cycles.
/Note
Dispose of the lithium ion battery pack in
accordance with local regulations.
An internal lithium battery maintains the tester’s clock,
when you remove the battery pack. This battery typically
lasts about 5 years. When the battery begins to fail, the
tester will lose the current date and time when you
remove the battery pack. If the internal lithium battery
fails, send the tester to a Fluke Networks service center for
a replacement.
