voltage pulses at the test points can damage the multimeter.
Use of a TV filter will attenuate any such pulses.
* Use the 9V NEDA battery, properly installed in the Meter's
battery case, to power the Meter.
* Replace the battery as soon as the battery indicator ( )
appears. With a low battery, the Meter might produce
false readings that can lead to electric shock and personal
injury.
* Do not measure voltages above 600V in Category Ⅳ, or
1000V in Category III installations.
* Do not operate the Meter with the case (or part of the case)
removed.

1.1.4 Instructions
* Remove test leads from the Meter before opening the
Meter case or battery cover.
* When servicing the Meter, use only specified replacement
parts.
* Before opening up the instrument, always disconnect from
all sources of electric current and make sure you are not
charged with static electricity, which may destroy internal
components.
* Any adjustment, maintenance or repair work carried out on
the meter while it is live should be carried out only by
appropriately qualified personnel, after having taken into
account the instructions in this present manual.
* A "qualified person" is someone who is familiar with the
installation, construction and operation of the equipment
and the hazards involved. He is trained and authorized to
energize and de-energize circuits and equipment in
accordance with established practices.
* When the instrument is opened up, remember that some
internal capacitors can retain a dangerous potential even
after the instrument is switched off.
* If any faults or abnormalities are observed, take the
instrument out of service and ensure that it cannot be used
until it has been checked out.
* If the meter is not going to be used for a long time, take out
the battery and do not store the meter in high temperature
or high humidity environment.
1.2 Protection mechanisms
* Fused by the fuse (FF400mA/1000V) during capacitance,
Inductance, mA and hFE measurements.
* A PTC resistor protects against permanent overvoltages of
up to 250V during resistance, continuity and diode test
measurements.
