and have read the information on calibration, performance test and
maintenance.
5.1 General maintenance
To avoid any electric shock or damage to the meter, do
not attempt to clean the inside of the meter. You
must remove the line connecting a test lead to input signals,
before opening the case or battery cover.
You must regularly use damp cloth and a small quantity of detergent to clean
the meter's shell. Don't attempt the use of any abrading or chemical solvent.
The dirty or damp input socket may affect reading.
Steps for cleaning input sockets:
⚫
Disenable the meter and pull all test leads out of the input socket.
⚫
Clean up all dirty substances on sockets.
⚫
Use a new cotton ball with a detergent or lubricant to clean each socket,
because lubricant can prevent the socket vulnerable to dampness from
pollution.
5.2 Battery & fuse replacement
To avoid any electric shock or personal injury as a result
of incorrect reading, replace batteries once the symbol “
” appear on the display unit.
Only the designated fuse (500mA/250V,10A/250V quick-
acting fuse) can be used.
To avoid any electric shock or personal injury, don't
attempt to open the battery cover to replace batteries,
unless you have already powered off the device and
carried out an examination to ensure that the test lead has
been disconnected from the circuit to be measured.
Battery replacement:
1. Turn off the power of the meter.
