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 Input protection measures
• When making voltage measurements (not including 200mV grade), the
maximum input voltage is 1000V DC or 750V 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 measu
-
rements, the meter is protected through a fuse (F250mA/250V).
