• Before the tests on electric resistance, diode, capacitor or continuity, the operator must cut off the
power supply to the circuit to be measured, and discharge all high-voltage capacitors within the
circuit to be measured.
• The electric resistance measurement or continuity test cannot be carried out in any live electrical
circuit.
• Before the current measurement, the operator must first examine the protective tube of the meter.
Before connecting the meter to the circuit to be measured, the operator must first power off the
aforesaid circuit.
• Before repairing TV sets or measuring power switching circuit, the operator must be careful enough
to prevent high amplitude voltage impulse from damaging the meter.
• This meter uses 4 x 1.5V AA batteries that must be correctly installed into the battery compartment.
• When appears, the batteries must be replaced immediately. The low level of a battery will
result in incorrect reading on the meter, which is likely to bring electric shock or personal injury to
the operator.
• In measurement, category III voltage and category IV voltage shall not exceed 1000V and 600V
respectively.
• The meter shall not be in service if its case (or part of its case) is dismantled.
