4.2. Testimisjuhtmete ühendamine

The multimeter is supplied with a pair of test leads (red and black).

• Sisestage must testjuhe sisse KOM (Üldine) sisendpesa.
• Enamiku mõõtmiste (mahttage, resistance, low current), insert the punane testjuhe sisse VΩmA sisendpesa.
• For high DC current measurements (up to 10A), insert the punane testjuhe sisse 10 ADC sisendpesa.

5. Kasutusjuhised

To operate the multimeter, select the desired function and range using the rotary switch.

5.1. Alalisvoolu volüümi mõõtminetage (DCV)

1. Insert the red lead into the VΩmA jack and the black lead into the COM jack.
2. Set the rotary switch to the desired DCV range (e.g., 200m, 2000m, 20, 200, 1000). Start with the highest range if the voltage on teadmata.
3. Ühendage testjuhtmed mõõdetava komponendi või vooluringiga.
4. Lugege kdtage väärtus LCD -ekraanil.

5.2. Measuring AC Voltage (ACV)

1. Insert the red lead into the VΩmA jack and the black lead into the COM jack.
2. Set the rotary switch to the desired ACV range (e.g., 200, 750). Start with the highest range if the voltage on teadmata.
3. Ühendage testjuhtmed mõõdetava komponendi või vooluringiga.
4. Lugege kdtage väärtus LCD -ekraanil.

5.3. Alalisvoolu (DCA) mõõtmine

4. For transistor hFE measurement, insert the transistor leads (Emitter, Base, Collector) into the appropriate sockets (E, B, C) in the hFE test socket, ensuring correct NPN or PNP type selection.
5. Loe hFE väärtust LCD-ekraanilt.

6. Hooldus

6.1. Puhastamine

Pühkige arvesti casing reklaamigaamp lapiga ja õrna pesuvahendiga. Ärge kasutage abrasiivseid aineid ega lahusteid. Enne kasutamist veenduge, et mõõteseade on täiesti kuiv.

7. Veaotsing

• Kuvarit pole: Kontrollige aku paigaldust ja veenduge, et aku laetuse tase oleks piisav.
• 'OL' or '1' on Display: This usually indicates an over-range condition or an open circuit. Select a higher range or check connections.
• Valed näidud: Ensure the correct function and range are selected. Check test lead connections and battery condition.
• Jätkuvuse puudumise toon: Verify the circuit is de-energized and the leads are making good contact.
