7. Cleaning Meter Cover
This earth tester 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 tester 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-statics agent or
detergent to wipe the meter cover surface.
