To ensure the meter is used safely, be sure to observe the instructio n
when using the instrument.
1.Never use meter on the electric circuits that Exceed 3 kVA.
2.Never apply an input signal exceeding the maximum rating input value.
3.Never use meter if the meter or test leads are damaged or broken.
4. 4Pay special attention when measuring the voltage of AC 30 Vrms(42.
V peak) or DC 60 V or more to avoid injury.
5. tNever use meter for measuring the line connected with equipmen
(i.e.motors) that generates induced or surge voltage since it ma y
exceed the maximum allowable voltage.

【 】2 APPLICATION AND FEATURES
This instrument is portable digital multimeter designed for measurement
of weak current circuits. It plays an important role in circuitry analysis by
using additional functions as well as measurements of small typ e
communication equipment, electrical home appliance, lighting voltage and
batteries of various type.
10.Be sure to disconnect the test pins from the circuit when changing
11. dBefore starting measurement, make sure that the function an
range are properly set in accordance with the measurement.
12.Never use meter with wet hands or in a damp environment.
13. .Never open tester case except when replacing batteries or fuse
Do not attempt any alteration of original specifications.
14. cDo not use the device near an item of strong electromagneti
generation or a charged item.
15. eTo ensure safety and maintain accuracy, calibrate and check th
tester at least once a year.

year to maintain the safety and accuracy.
6-1 Maintenance and inspection
●Is the appearance not damaged by falling?
●Is the cord of the test leads not damaged?
●Is the core wire not exposed at any place of the test leads?
If the built-in fuse is blown, only the current measurement becomes impossible.
Make sure that the test leads are not cut, referring to the section 5-1.
The manufacturer may conduct the calibration and inspection. Fo r
more information, please contact the dealers.
6-3 Battery and Fuse Replacement
1. If the rear case or the battery lid is removed with input applied to
the input terminals, you may get electrical shock. Before startin g
the work, always make sure that no input is applied.
2. Before starting the work, be sure to turn OFF the main unit power
and release the test leads from the circuit.
3. Be sure to use a fuse of the specified rating or type. Never use a
substitute of the fuse or never make a short circuit of the fuse.
Set battery with its polarities facing in the correct directions.
①Remove the battery lid screw with a screwdriver.
②Take out the battery or fuse and replace it with a new one.
③Attach the battery lid and fix with the screw.
