11.  The internal circuit of the meter shall not be altered that will avoid damages of the meter and any accident Soft cloth and 

mild detergent should be used to clean the surface of the meter when servicing. No abrasive and solvent should be used to 

prevent the surface of the meter from corrosion, damage and accident.

12.  Please check whether the instrument is in good condition before use, such as test the voltage which is known and confirm 

the reading are accurate.

3. International Electrical Symbols

Deficiency of Built in Battery

Grounding

Warning: Refer to the Operating Manual
AC (Alternating Current)
DC (Direct Current)
Double Insulated
Conforms to Standards of European Union

2. Power Button
3. Rotary Switch

5. Hold Button

5. Measurement Operation

First check on 9V battery, then turn rotary switch to the measuring position. If the low battery, “ ” sign will be displayed on LCD 

panel. Nearly to “ ” sign on the meter front panel terminal input which also not exceed the testing voltage and current input 

value limitation.

1. DC or AC Voltage Measurement (See Diagram 2)

1) Turn rotary switch to V~ or V

 voltage measurement.

2)  Insert the red test lead into the “V” terminal and the black test lead into the “COM” terminal, connect the test leads across with 

the object being measured. The measured value show on the display AC Voltage measurement shows on True root mean 

square value stability period.

3)  In each range, the meter has an input impedance of 10MΩ. V ~ Input impedance is about 4.5MΩ. This loading effect can 

cause measurement errors in high impedance circuits. In the circuit impedance is less than or equal to 10kΩ, the error is 

negligible (0.1% or less).

 Warning:

  

To avoid possibly damages to the meter, please do not attempt to input higher than 600V. 

To avoid electrical shock, please pay attention during the high voltage measurement.
