Introduction
This digital multimeter can measure AC/DC voltage, AC/DC current, resistance, diode, the
voltage of battery, temperature. The meter complies with international safety standards
EN61010-1,61010-2-030, 61010-2-033, CAT III 600V and pollution degree of 2.
Read all instructions carefully before using the meter and follow all relevant safety standards.
To ensure safe usage of this instrument, please read the following carefully:
WARNING
The special attention should be paid when using the meter because the improper usage may
cause electric shock and damage the meter .The safety measures in common safety regulations
and operating instruction should be complied with when using. In order to make fully use of its
functions and ensure safe operations please compl y with the usage in this section carefully.
Safety Guidelines
To ensure safe usage of this instrument, please read the following carefully:
Precautions
• All the instrument to warm up for 30 sec. before measurement.
• Inspect the case before use. Check for cracks in the casing and the insulation around
the input sockets.
• Only use the test leads provided with the meter.If leads are damaged or need to be
replaced, use similar leads with matching specifications.
• Ensure the meter works properly by testing a known voltage source first.If not working
properly, the protective equipment may be damaged; have the meter serviced before using.
• Do not place meter in a strong magnetic field; this may cause false readings.
• Do not place the meter in any environment with high pressure, high temperature, dust,
explosive gas or vapor.
• Make sure the test leads are in the correct input jacks before measurement.
• Choose the highest range when the value to be measured is unknown beforehand.
• Never exceed the protection limit values indicated in the specifications for each range of measurement.
• Do not perform a voltage test using the 10A input jack.
• Always be careful when working with voltages above 60V DC or 30V AC rms. Keep
fingers behind the probe barriers when making voltage measurements.
• When connecting the test leads to a measurement circuit, connect the common lead first,
then the live lead. Reverse when disconnecting.
• Disconnect leads from circuit before switching functions/ranges.
• Disconnect leads from circuit before testing transistors.
• Turn off power to circuit and discharge all capacitors before making resistance, continuity
or diode measurements.
• Before making current measurements, turn off power to the circuit, break the circuit,
connect the leads in series across the break, then turn the power back on for measurement.
• When the
symbol appears, replace the batteries to avoid incorrect readings.
Maintenance
• Maintenance/calibration should only be performed by professionals.
• For continued protection against fire, replace fuse only with the specified voltage and
current ratings listed in the manual : F1 400mA/600V and F2: 10A/600V
• Before opening the case, always disconnect test leads from all energized circuits.
• Never use the meter unless the back cover is in place and fastened securely.
• If any abnormality is observed, stop using the meter and send it in for repair.
• If the meter is not goi ng to be used for an extended period of time, remove the batteries
and avoid storing in a hot/humid environment.
Cleaning the Meter
WARNING
Before opening the back cover, turn off the meter and disconnect test leads from any circuit.
Clean meter with a damp cloth and mild detergent; do not use chemical solvents on the
meter. Dirt or moisture on the input jacks can affect the reading of the meter.
To clean the input jacks:
• Turn the rotary switch to OFF and remove test leads.
• Remove all dirt from the input jacks.
• Use a detergent or lubricant with a cotton swab to clean the jacks.Use a new cotton swab
for each jack to prevent cross contamination.
Replacing the Probe
If insulation on probe is damaged, replace it.
WARNING
Use meet EN 61010-031 standard, rated CAT III 600V, 10A or better probe.
Replacing the Battery and Fuses
• Under normal conditions, it is unnecessary to replace the fuse. Don't replace it until the
probes are unplugged and the power is shut down. Take out the two screws of the rear
cover to remove the housing.
• The specification of the fuse is: F1 400mA/600V, F2 10A/600V. The replacement should
be of the same specification.
• The battery for this multimeter is 9V NEDA 1604 or 6F22. The replacement should be of
the same specification.
• Don't put the instrument into use until the rear cover is screwed after replacing battery or fuse.
WARNING
To avoid electric shock, make sure the probes are disconnected from the measured circuit before
removing the rear cover. Make sure the rear cover is tightly screwed before using the instrument.
