can be removed with a moist cloth ( 99% water, 1% mild detergent) spirit or washing
benzene (petroleum ether) can be used to remove greasy dirt. The display may be
cleaned with water or washing benzene (but not with spirit-alcohol solvents), it must
then be wiped with a dry clean lint-free cloth. Under no circumstances the cleaning
fluid should get into the instrument. The use of cleaning agents can attack the
plastic & paint surfaces.
The power line fuse is located on rear panel on lower right side. In case, the
instrument does not show any sign of working, no LED is lit or there is no display
immediately switch OFF the mains power switch of the instrument and unplug the
mains cord from the mains socket. With the help of small flat blade screwdriver
remove the fuse cap of the fuse holder, located just below the socket. There is one
spare fuse kept in the fuse cap, replace it for the defective one. Press the cap so
that it locks in place . The rating of the fuse is 3 A , 250 V, sloblow , 5x20 mm glass
