Battery & Fuse Replacement

WaRninG: To avoid electric shock, disconnect the test leads from any 

source of voltage before removing the battery or fuse cover. 
Do not operate your meter with the cover removed. Be sure 
it is in place and fastened securely.

Battery Replacement

When the battery level gets low or falls below the operating voltage, the 
battery warning symbol will appear in the LCD display.
1. Disconnect the test leads from the meter.
2. Open the battery cover by loosening the screws using a Phillips head 

screwdriver.

3. Insert the battery into battery holder, observing the correct polarity.
4. Put the battery cover back in place. Secure with the two screws.
noTE: If your meter does not work properly, check the fuses and battery 

to make sure that they are still good and that they are properly 
inserted.

Replacing The Fuses

1. Disconnect the test leads from the meter and any item under test.
2. Open the fuse door by loosening the screw on the door using a Phillips 

head screwdriver.

3. Remove the old fuse from its holder by gently pulling it out. 
4. Install the new fuse into the holder.
5. Always use a fuse of the proper size and value 

 

(F1 500mA / 600V fast blow, F2 10A / 600V fast blow).

6. Put the fuse door back in place. Insert the screw and tighten it securely.
