accuracy and reliability. The instrument is carefully tested and calibrated using
standards traceable to National Laboratories.
Take care of your instrument by cleaning the exterior of the instrument regularly
with a dusting brush. Dirt which is difficult to remove on the casing & plastic parts,
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, slow blow, 5x20 mm glass
fuse. Do not use a fuse with a higher value other wise it may damage the
instrument in case, the mains voltage goes much higher than the rating of the
mains fluctuation of 10%.
