How to Test the Fuse

To manually check the fuse:

2. Select the input as L-PE.
3. Short the L-PE leads.

5. If the fuse is bad, FUSE will appear on the display to indicate the Tester is
damaged and needs repair. Contact Fluke Service for repair (see How to
Contact Fluke).

How to Test the Battery

Battery voltage is continuously monitored by the Tester and shows the current
capacity in 25 % increments. If the voltage falls below 6.0 V (1.0 V/cell), the
battery icon shows 0 % to indicate minimal battery life is available.
To test:
1. Turn the rotary dial to V.
2. Press and hold .
The battery voltage shows in the secondary display.
To prevent possible electric shock or personal injury due to false
readings:
•
Replace the batteries as soon as the - empty battery icon
appears.
•
Be sure that the battery polarity is correct. A reversed battery
can cause leakage.

Battery Replacement

Replace the batteries with six AA batteries. Alkaline batteries are supplied with
the Tester. You can also use 1.2 V NiMH batteries. Due to the nature of these
NiMH batteries, the battery symbol on the Tester display may indicate a lower
power level even when batteries are fully charged.
