Warning
To avoid possible electric shock or personal injury, follow these guidelines:
●Do not use the meter if it is damaged. Before you use the meter, inspect the case. Look for
cracks or missing plastic. Pay particular attention to the insulation surrounding the
connectors.
●Inspect the test leads for damaged insulation or exposed metal. Check the test leads for
continuity. Replace damaged test leads before you use the meter.
●The RESPONSIBLE BODY shall be made aware that, if the equipment is used in a manner
not specified by the manufacturer, the protection provided by the equipment may be impaired.
●Do not use the meter if it operates abnormally. Protection may be impaired. When in doubt,
have the meter serviced.
●Do not operate the meter around explosive gas, vapor, or dust.
●Do not apply more than the rated voltage, as marked on the meter, between terminals or
between any terminal and earth ground.
●Before use, verify the meter’s operation by measuring a known voltage.
●When measuring current, turn off circuit power before connecting the meter in the circuit.
Remember to place the meter in series with the circuit.
●When servicing the meter, use only specified replacement parts.
●Use caution when working above 30 V ac rms, 42 V peak, or 60 V dc. Such voltages pose a
shock hazard.
●The finger or any part of your body shall not be beyond the barrier of the test probe
when measuring.
●Avoid working alone.
●When using the probes, keep your fingers behind the finger guards on the probes.
●Connect the common test lead before you connect the live test lead. When you disconnect
test leads, disconnect the live test lead first.
●Remove test leads from the meter before you open the battery door.
●Do not operate the meter with the battery door or portions of the cover removed or loosened.
●To avoid false readings, which could lead to possible electric shock or personal injury,
replace the batteries as soon as the low battery indicator (
) appears.
●Use only One standard 9 volt battery (NEDA 1604, IEC 6F22 or equivalent), properly installed
in the meter case, to power the meter.
●To avoid the potential for fire or electrical shock, do not connect the thermocouples to
electrically live circuits.
Caution
To avoid possible damage to the meter or to the equipment under test, follow these guidelines:
●Disconnect circuit power and discharge all high-voltage capacitors before testing resistance,
continuity, diodes, or capacitance.
●Use the proper terminals, function, and range for your measurements.
●Before measuring current, check the meter’s fuses and turn power OFF to the circuit before
connecting the meter to the circuit.

3.1 CARING FOR YOUR MULTIMETER
Your Digital MultiMate is an example of superior design and craftsmanship. The following
suggestions will help you care for the multimeter so you can enjoy it for years.
1) Keep the multimeter dry. If it gets wet, wipe it dry immediately. Liquids can contain minerals that
can corrode electronic circuits.
2) Use and store the multimeter only in normal temperature environments. Temperature extremes
can shorten the life of electronic devices, damage batteries, and distort or melt plastic parts.
3) Handle the multimeter gently and carefully. Dropping it can damage the circuit boards and case
and can cause the multimeter to work improperly although the holster can provide enough
protection.
4) Keep the multimeter away from dust and dirt, which can cause premature wear of parts.
5) Wipe the multimeter with a damp cloth occasionally to keep it looking new. Do not use harsh
chemicals, cleaning solvents, or strong detergents to clean the multimeter.
6) Use only fresh batteries of the required size and type. Always remove old or weak batteries. They
can leak chemicals that destroy electronic circuits.
3.2 MAINTENANCE
9-Volt battery replacement or fuse replacement
WARNING
TO AVOID ELECTRIC SHOCK，REMOVE TEST LEADS BEFORE OPENING CASE
AND BATTERY DOOR.
a) Ensure the instrument is not connected to any external circuit. Set the selector switch to
“OFF“position and remove the test leads from the terminals.
b) Remove the screw on the battery case and lift the battery case. Remove the spent battery and
replace it with a battery of the same type.
Pull up the box case
Battery: One standard 9
volt battery (NEDA 1604,
IEC 6F22 or equivalent)

c) Do not dispose the batteries with the household waste. Refer to your local area for the proper
disposal of used batteries.
d) Remove the screws on the bottom case and lift the case. Replace only with the same type and
