Charging the battery
A new rechargeable battery comes in a
discharged condition and must be charged before
use (refer to the
U1401B User's and Service Guide
for charging instructions). Upon initial use (or
after a prolonged storage period) the
rechargeable battery may require three to four
charge/discharge cycles before achieving
maximum capacity. To discharge, simply run the
multimeter using the rechargeable battery’s
power until it shuts down or until the low battery
warning appears.
In some instances, the multimeter may indicate
that the charging is complete after ten minutes or
so when charging a new rechargeable battery.
This is a normal phenomenon with rechargeable
batteries. Remove the rechargeable battery from
the device, re-insert it and repeat the charging
procedure.
