To guarantee the accuracy of the multimeter over a prolonged period of
time, it should be calibrated annually. Fuse replacement is under 3.
(Safety requirements). Battery replacement can be found under 4.4.1.
To clean the instrument or the display window, take a clean, lint-free,
anti-static, dry cleaning cloth.
Attention!
Use no carbonaceous cleaners or petrols, alcohols or similar for cleaning.
Otherwise the surface of the measuring instrument will be attacked. In
addition, the vapours are damaging to health and explosive.. Also use
no sharp-edged tools, screwdrivers or metal brushes or similar for clea-
ning.
