When making measurement with a test lead, place your fingers
behind its 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, 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:
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.
High voltage warning
Equipment with double insulation or reinforced
insulation protection
AC (alternating current)
