Testing and Replacing the Batteries
Battery voltage is continuously monitored by the tester. If
the voltage falls below 6.0 V (1.0 V/cell), the low battery
icon B appears on the display, indicating that there is
minimal battery life left. The low battery icon continues to
appear on the display until you replace the batteries.
XW Warning
To avoid false readings, which could lead to
possible electric shock or personal injury,
replace the batteries as soon as the battery
icon (B) appears.
Replace the batteries with six AA batteries. Alkaline
batteries are supplied with the tester but you can also use
1.2 V NiCd or NiMH batteries. You can also check the
battery charge so that you can replace them before they
discharge.
XW Warning
To avoid electrical shock or personal injury,
remove the test leads and any input signals
before replacing the battery or fuses. To
prevent damage or injury, install ONLY
specified replacement fuses with the
amperage, voltage, and speed ratings shown
in the General Specifications section of this
manual.
To test the batteries
1. Turn the rotary switch to the V position.
2. Press the 3 button to initiate the battery test. The
Voltage function display clears and is replaced by the
measured battery voltage in the secondary display for
2 seconds, the Voltage function display then returns.
