1.1.4 Safe maintenance habits
* To open the meter shell or remove the battery cover, you
should first pull out the test probe.
* When performing meter maintenance, you should use
specified replacement parts.* Before opening the meter,
you should disconnect all power supplies and ensure that
you have no static electricity to avoid damaging the meter
components.
* Meter calibration, maintenance, repair and other operations
only can be performed by technicians who fully understand
the meter and electrical shock hazards.
* Before opening the meter, you should be aware that there
may be dangerous voltages remaining in some capacitances
in the meter even after powering off.
* If you find any abnormal phenomena on the meter, the meter
should be immediately turned off and repaired. Ensure that it
can not be used before passing inspection.
* When the meter is not used for a long time, please remove
the battery and avoid storing it in a high temperature and
humidity environment.
1.2 Input protection measures
* When making voltage measurements (not including 200mV
grade), the maximum input voltage is 600V DC or 600V AC.
(The maximum input voltage of 200mV grade is 250V AC or
equivalent RMS value voltage).
* When making frequency, resistance, on-off and diode
measurements, the maximum voltage is 250V AC or
equivalent RMS value voltage.
* When making capacitance, temperature, mA current, and
triode hFE measurements, the meter is protected through
a fuse (FF 400mA H 600V).
