AC voltage.
Before the tests on electric resistance, diode, 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 3 x 1.5V AAA 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 II voltage shall not exceed 600V respectively.
The meter shall not be in service if its case (or part of its case) is dismantled.
1.1.3 Safety symbol:
The safety symbols that appear on the meter's body and in this Operation Manual:
CAT. II 600 V
1.1.4 Maintenance practices for safety
The operator must first pull out the test lead when the meter's case is opened or
the battery cover is dismantled.
Warning, an important safety symbol. The operator must consult
this Operation Manual before using the meter. Unintended use
may lead to the damage to the device or its components.
