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.
