3. Safety Information
3-1 The meters are designed according to IEC-61010 concerning electronic
measuring instruments with an over-voltage category (CAT III) and
pollution 2.
3-2 Follow all safety and operating instructions to ensure that the meter is
used safely and is kept in good operating condition.
3-3 Safety symbols:
Important safety information, refer to the operating manual.
Dangerous voltage may be presence.
Double insulation (protection Class II)
4. Special Cautions for Operation
4-1 The meters can be safe only according to standard procedures when
used in conjunctions with the supplied test leads. To replace damaged
test leads with only the same model or same electric specifications.
4-2 To avoid risk of electric shock, do not use the meters before the cover
is in place.
4-3 The range switch should be right position for the testing.
4-4 To avoid electric shock and damaging the instruments, the input
signals are forbidden to exceed the specified limits.
4-5 When measuring TV set or switched power, attention should be paid
to the possible pulses that may bring destruction to the circuit.
4-6 Range switch position is forbidden to be changed at random during
measurement.
4-7 Take caution against shock in the course of measuring voltage higher
than DC 60V & AC 30V.
4-8 Protection fuse should be replaced only with same type and same
specification.

1. Overview
The multimeter is characterized at slim size, portable, stable performance
and anti-dropping capacity. Using 3 ½ digits LCD monitor with character
15mm high, they offer clear readings. With overall circuitry design centering
on large-scale IC A/D converters in conjunction and over-load protection
circuit, the meters give excellent performance and exquisite making as a
handy utility instrument.
The meters can be used to measure AC & DC voltage, DC current,
resistance, positive diode voltage fall and continuity.
