DMM OPERATOR’S MANUAL
1. Overview
The multimeter is characterized at slim size, portable, stable performance and
anti-dropping capacity. Using 3½ digits LCD monitor with character 16mm 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 DC & AC voltage, DC & AC current,
resistance, capacitor, battery positive diode voltage fall, hfe parameters for
transistor and Continuity.
2. Panel Layout
① LCD Display: 3½ digits, character 16mm high
② Data-hold Switch (HOLD)
③ Back Light Button Switch: Press this button to switch on back light If the
dark circumstance light makes the reading difficulty when measuring, the light
will be automatically turned off in 5 seconds. Press again to switch it on again.
If the battery is in weak power, the light will be dimmed.
④ Rotary Switch: use this switch to select functions and ranges
⑤ V Ω mA Cx+ Input Jack、Cx- Input Jack、COM Input Jack
3. Safety Information
3-1 The meters are designed according to IEC-1010 concerning electronic
measuring instruments with an over-voltage category (CAT Ⅱ) 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 avid 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 ot measuring voltage higher
than DC 60V & AC 30V.
4-8 Protection fuse should be replaced only with same type and same
specification.
