Extending Battery Operation Time

Typically, NiMH batteries always meet the specified
operating time. However, if the batteries have been
extremely discharged (for example, when empty batteries
were stored for a long period) it is possible that the battery
condition has deteriorated.
To keep the batteries in optimal condition, observe the
following guidelines:
•
Operate the test tool on batteries until the
appears at the bottom of the screen. This indicates
that the battery level is low and that the NiMH
batteries need to be recharged.

To obtain optimal battery condition again, you can
refresh the batteries. During a battery refresh, the
batteries will be fully discharged and charged again.
A complete refresh cycle takes about 12 hours and
should be done about four times a year. You can check
the latest battery refresh date. See section "Displaying

To refresh the battery, make sure that the test tool is line
powered and proceed as follows:
