2.2 Pripojenie meracích káblov
The multimeter comes with two test leads, typically one red (positive) and one black (negative/common). Proper connection is crucial for accurate and safe measurements.
- Pre väčšinu objemutage, resistance, and low current measurements, connect the black lead to the 'COM' (Common) jack.
- Connect the red lead to the 'V-Ω-mA' jack for voltage, odpor a miliampaktuálne merania.
- Pre meranie vysokého prúdu (do 10 A) pripojte červený vodič do zásuvky „10 A“. Always ensure the correct jack is used to prevent damage to the meter or circuit.

3.1 Meranie jednosmerného objtage (DCV)
- Set the rotary dial to the desired DCV range (e.g., 200m, 2, 20, 200, 1000). Choose a range higher than the expected voltage.
- Connect the red lead to the positive (+) side of the circuit and the black lead to the negative (-) side.
- Prečítajte si svtage hodnota na displeji.
3.2 Meranie AC objtage (ACV)
- Set the rotary dial to the desired ACV range (e.g., 200m, 2, 20, 200, 750). Choose a range higher than the expected voltage.
- Pripojte testovacie káble cez AC voltage source. Polarity does not matter for AC voltage.
- Prečítajte si svtage hodnota na displeji.
3.3 Meranie odporu (Ω)
- Pred meraním odporu sa uistite, že obvod alebo súčiastka je bez napätia.
- Set the rotary dial to the desired Ω range (e.g., 200, 2K, 20K, 200K, 2M, 20M, 200M).
- Pripojte meracie káble k meranému komponentu.
- Odčítajte hodnotu odporu na displeji.
3.4 Meranie jednosmerného prúdu (DCA)
- Uistite sa, že obvod je bez napätia.
- Set the rotary dial to the desired DCA range (e.g., 200µ, 2m, 20m, 200m, 10A).
- Dôležité: For currents up to 200mA, use the 'V-Ω-mA' jack for the red lead. For currents up to 10A, use the '10A' jack.
- Break the circuit and connect the multimeter in series with the load. The current must flow through the multimeter.
- Znovu zapnite obvod a odčítajte hodnotu prúdu.
3.5 Meranie striedavého prúdu (ACA)
- Uistite sa, že obvod je bez napätia.
- Set the rotary dial to the desired ACA range (e.g., 200µ, 2m, 20m, 200m, 10A).
- Dôležité: For currents up to 200mA, use the 'V-Ω-mA' jack for the red lead. For currents up to 10A, use the '10A' jack.
- Prerušte obvod a zapojte multimeter sériovo so záťažou.
- Znovu zapnite obvod a odčítajte hodnotu prúdu.
3.6 Measuring Capacitance (CX)
- Pred testovaním sa uistite, že je kondenzátor úplne vybitý.
- Set the rotary dial to the CX range (e.g., 2n, 20n, 200n, 2µ, 20µ).
- Pripojte testovacie vodiče na svorky kondenzátora.
- Prečítajte si hodnotu kapacity na displeji.
3.7 Diode and Transistor (hFE) Testing
Refer to the specific markings on the dial for diode and transistor testing functions. Typically, diode test mode allows checking the forward voltage drop of a diode, and hFE mode is used for measuring the DC current gain of transistors.
