1.4 MAINTENANCE

* Before opening the meter, always disconnect test leads from all sources of electric

current.

* For continue protection against fire, replace fuse only with the specified and current

rating: F200mA / 250V (quick acting)

*If any faults or abnormalities are observed, the meter can not be used any more and

it has to be checked out.

*Never use the meter unless the back cover is in place and fastened fully.

*Do not use abrasives or solvents on the meter use a damp cloth and mild detergent

only.
