The tester is powered either by an 8.4V NiMH rechargeable battery or by an AC adapter. Since these
batteries are subject to self discharge, it may be necessary to recharge the unit after a prolonged period
of storage. Plug the accompanying charger into the AC outlet and insert the charger plug into the
receptacle on the tester (refer to the illustration below). The battery will fully charge in approximately 8
hours.
Caution!
Do not use chargers or batteries other than supplied or instrument damage may occur.
If the AC adapter is plugged in, an icon appears in the lower left corner of the display, as follows:
If the AC adapter is not plugged in, battery power drainage is denoted in a five-step process:
1. When battery life is greater than 75%, the following indicator is present:
2. When battery life is between 50% and 75%, the following indicator is present:
3. When battery life is between 25% and 50%, the following indicator is present:
4. When battery life is less than 25%, the following indicator is present:
5. When battery life drops to approximately 2%, the indicator from step 4 will be flashing.
Several minutes after (timing depends on usage and whether the backlight is turned on or
off), a message will appear, “BATTERY VOLTAGE TOO LOW. POWERING OFF”. A 4-tone
audio indicator will sound and the tester will power off.
The tester can be configured to automatically power off following a period of inactivity. Refer to the Other
Settings section for details.
If battery replacement is necessary, the battery may be accessed by removing the sheet metal cover on
the underside of the base.
