Maintaining the Test Tool

Keeping Batteries in Optimal Condition

Always operate the test tool on batteries until an -icon

appears on the bottom line of the screen. This indicates

that the battery level is low and that the batteries need to

be recharged.

Frequent charging of the batteries when they are not

completely empty can reduce the operating time for the

test tool.

You can refresh the battery pack at any time. This battery

refresh cycle fully discharges and charges the battery pack.

A complete refresh cycle takes about 14 hours (Fluke 123

with Ni-Cd battery) or 19 hours (Fluke 124 with Ni-MH

battery) and should be done at least four times a year.

Note

Be sure not to disconnect the Power Adapter

during the complete refresh cycle. Doing so will

interrupt the refresh cycle.

To refresh the battery pack, do the following:

• Be sure that the test tool is line powered.

 Open the USER OPTIONS menu.

 Open the BATTERY REFRESH

submenu.

 Highlight START REFRESH.

 Start the refresh cycle.

Note

After start of the refresh cycle, the screen will be

black.The backlight is on during discharging

within the refresh cycle.
