Fuse Replacement
The DC µA position is protected by a 400 mA fuse. If this fuse blows the
meter will display all zeros (example, 00.00 mA) on the LCD when the
DC µA function is selected, regardless of input.

WARNING!
To avoid the potential of electric shock or personal injury, disconnect
the test probes from any potential power source before removing the
fuse. Replace the blown fuse with the fuse specified for this meter only.

fuse. Replace the blown fuse with the fuse specified for this meter only.
To replace a blown fuse, follow these procedures:
1. Turn off power to the circuit under test.
2. Turn off the meter.
3. Disconnect the test leads from the circuit or component under test.
4. Open the battery/fuse compartment cover. The fuse is visible above
the battery above the battery compartment (Fig 1).
5. Pull the fuse from the fuse holder.
6. Check the fuse by confirming that there is no continuity. The ohms
and continuity functions will work with the fuse out. Do not attempt
to make circuit measurements with the battery cover off. Live
voltages may be present at the fuse holder.

Cleaning and Decontamination
Periodically clean your meter’s case using a damp cloth. DO NOT use
abrasives, cleaning solvents or strong detergents, as they may damage
the finish or affect the reliability of the structural components.

Battery Replacement
Always use a fresh replacement battery of the specified size and ty p e .
Immediately remove the old or weak battery from the meter and dispose
of it in accordance with your local disposal regulations. Old or defective
batteries can leak chemicals that corrode electronic circuits.

WARNING!
To avoid electric shock, be sure to turn off the meter’s power and
disconnect both test leads from any equipment before you remove or
install batteries.

To install a new battery, follow these procedures:
1. Remove the screw from the battery compartment cover on the
back (lower half) of the meter and lift the cover (Fig 1).
2. Remove and discard the old battery. Always dispose of old batteries
promptly in a manner consistent with local disposal regulations.
WARNING!
Under NO circumstance should you expose batteries to extreme heat or
fire as they may explode and cause injury.

3. Place a fresh 9V battery in the compartment.
NOTE: If you do not plan to use the meter for a month or more,
remove the battery and store it in an area that won’t be damaged by
a leaking battery.
