Battery and Fuse Replacement
Electric shock hazard:
Before opening the case, remove the test leads from the circuit and shut off the unit.
Failure to observe this warning could result in severe injury or death.
Electric shock hazard:
The fuse is an integral part of the overvoltage protection. When fuse replacement is necessary, refer
to "Specifications' for the correct type, size and capacity. Using any other type of fuse will void the
overvoltage protection rating of the unit.
Failure to observe this warning could result in severe injury or death.
1. Disconnect the unit from the circuit. Turn the unit OFF.
2. Turn the latch 1/4 turn counterclockwise.
3. Remove the back cover.
4. Replace the batteries (observe polarity) and/or fuse.
5. Replace the cover and turn the latch 1/4 turn clockwise to secure.
Cleaning
Periodically wipe the case with a damp cloth and mild detergent; do not use abrasives
or solvents.
