1.4 Precautions

1.4.1 Do not adjust or repair the meter by attempting to
remove the rear case. Such operation should only
be performed by a technician who fully understands
the meter and the electric shock risk involved.
1.4.2 Remove the test probes from the circuit under test
before opening the battery cover of the meter.
1.4.3 To avoid any electric shock caused by erroneous
readings, replace the batteries immediately when
03
the" " symbol appears on the LCD.
1.4.4 To avoid fire hazards, the replacement fuse must
meet the specified voltage and current ratings of F
10A/500V and F200mA/1000V (quick acting).
1.4.5 Use wet cloth and mild detergent to clean the
meter; do not use abrasives or solvents.
1.4.6 Turn to OFF switch off the power when is not in use.
1.4.7 Remove the batteries to avoid damages to the
meter if it will idle for a long time.
1.4.8 Using this appliance in an environment with a
strong radiated radio-frequency electromagnetic
field (approximately 3V/m ),may influence its
measuring accuracy. The measuring resul can be
strongly deviating from the actual value.

2. Description
