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 symbol 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 Calibration Information”.

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

1	Display the USER key labels.
2	Open the User Options menu.

A message appears asking whether you want to start the refresh cycle now.

3 Start the refresh cycle.

Do not disconnect the battery charger during the refresh cycle. This will interrupt the refresh cycle.

Note

After starting the refresh cycle, the screen will be black.
