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
4. The Meter Structure (see diagram 1)
1. LCD Display
2. Power Button
3. Rotary Switch
4. Input Terminals
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.
