protective ring.
When switching to another measuring range, be sure that test lead has
already been taken off the measured circuit.
For all DC functions, to prevent potential electric shock as a result of
incorrect reading, please first use AC functions to check the absence of
any AV voltage. Then, select DC voltage measuring range equivalent to or
greater than that for AC voltage.
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.
1.1.3 Safety symbol:
The safety symbols that appear on the meter's body and in this Operation
Manual:
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.
