10. Cleaning of the Instrument

◎ Cleaning the meter cover

This instrument is managed by our company's quality standard and is

delivered in the best condition after passed the inspection. But in the dry time

of winter static electricity sometimes builds up on the meter cover due to the

characteristic of plastic.

When the pointer deflects by touching the surface of this instrument or zero

adjustment can not be made, do not try to make measurement.

When static electricity builds up on the meter cover and affects the meter

reading, use a cloth dampened with off-the-shelf anti-static agent or detergent

to wipe the meter cover surface.

11. Service

If this tester should fail to operate correctly, return it to your nearest

distributors stating the exact nature of the fault.

Before returning the unit, make sure that:

a) probes have been checked.

b) fuse has been checked.

c) battery has been checked.

Remember, the more information written about the fault, the quicker it will be

serviced.
