• 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.

Safety Guidelines
To ensure safe usage of this instrument, please read the
following carefully:
1.1.1 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.

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 comply with the usage in this
section carefully.
• 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.
1.1.2 Safety Symbols
Fuse must be replaced as per the specification
herein.
Note-Important safety information, refer to the
instruction manual.
