MAINTENANCE

WARNING:

When servicing, use only identical replacement parts.

Use of any other parts may create a hazard or cause

product damage.

GENERAL MAINTENANCE

Avoid using solvents when cleaning plastic parts. Most

plastics are susceptible to damage from various types of

commercial solvents and may be damaged by their use. Use

clean cloths to remove dirt, dust, oil, grease, etc.

If the multimeter is not operating properly, check the battery

and the fuses. Then recheck the instructions in this manual

to verify correct operating procedures.

WARNING:

Do not at any time let brake fluids, gasoline, petroleum-

based products, penetrating oils, etc., come in contact

with plastic parts. Chemicals can damage, weaken or

destroy plastic which may result in serious personal

injury.

CLEANING THE TERMINALS

Dirt or moisture in the terminals can affect readings.

To clean the terminals:

 Set the mode selection dial to OFF position and remove

the test leads from the meter.

 Remove battery cover and the battery pack. Reinstall the

battery cover.

 Shake out any dirt which may exist in the terminals.

 Soak a new swab with alcohol.

 Work the swab around in each terminal.

REPLACING THE FUSE

See Figure 13, page 15.

To prevent damage or injury, install only replacement fuses

with the specified amperage, voltage, and interrupt rat-

ings.

This meter uses two fuses:

Fuse 1:

F 400mA 690V, Fast, Min. Interrupt Rating 10000A,

ø10 x 38mm

Fuse 2:

F 10A, 600V/690V, Fast, Min. Interrupt Rating 10000A,

ø10 x 38 mm

To replace the fuses:

 Disconnect the test leads.

 Remove battery cover and the battery pack. Reinstall the

battery cover.

 Remove the 6 Torx screws on the back cover.

NOTE: The screws are not all the same length. The

illustration shows the location of the longer and shorter

screws.

 Replace the blown fuse with an identical fuse of the same

rating.

 There are two posts on the circuit board and two springs

on the inside back cover of the unit. When replacing the

back cover, make sure the springs fit over the posts.

NOTE: Failure to correctly place the springs over the

posts can result in damage to the unit.

 Reinstall the back cover and all the screws.

PRODUCT STORAGE

product.

BATTERY PACK PREPARATION FOR

RECYCLING

Upon removal, cover the battery pack’s terminals with

heavy-duty adhesive tape. Do not attempt to destroy or

disassemble battery pack or remove any of its compo-

nents. Lithium-ion batteries must be recycled or disposed

of properly. Also, never touch both terminals with metal

objects and/or body parts as short circuit may result.
