2.2 Testkabels ferbine
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.
- Foar de measte folumetage, 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, wjerstân, en milliampere stroommjittingen.
- For high current measurements (up to 10A), connect the red lead to the '10A' jack. Always ensure the correct jack is used to prevent damage to the meter or circuit.

3.1 mjitten DC Voltage (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.
- Lês de voltage wearde op it display.
3.2 AC Voltage (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.
- Ferbine de testkabels oer it AC-volumetage source. Polarity does not matter for AC voltage.
- Lês de voltage wearde op it display.
3.3 Wjerstân mjitte (Ω)
- Soargje derfoar dat it sirkwy of komponint spanningsleas is foardat jo de wjerstân mjitte.
- Set the rotary dial to the desired Ω range (e.g., 200, 2K, 20K, 200K, 2M, 20M, 200M).
- Ferbine de testkabels oer it te mjitten komponint.
- Lês de fersetswearde op it display.
3.4 Mjitting fan gelijkstroom (DCA)
- Soargje derfoar dat it sirkwy spanningsleas is.
- Set the rotary dial to the desired DCA range (e.g., 200µ, 2m, 20m, 200m, 10A).
- Belangryk: 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.
- Re-energize the circuit and read the current value.
3.5 Measuring AC Current (ACA)
- Soargje derfoar dat it sirkwy spanningsleas is.
- Set the rotary dial to the desired ACA range (e.g., 200µ, 2m, 20m, 200m, 10A).
- Belangryk: For currents up to 200mA, use the 'V-Ω-mA' jack for the red lead. For currents up to 10A, use the '10A' jack.
- Ferbrek it circuit en ferbine de multimeter yn searje mei de lading.
- Re-energize the circuit and read the current value.
3.6 Measuring Capacitance (CX)
- Soargje derfoar dat de kondensator folslein ûntladen is foardat jo testen.
- Set the rotary dial to the CX range (e.g., 2n, 20n, 200n, 2µ, 20µ).
- Ferbine de testkabels oer de kondensatorterminals.
- Lês de kapasiteitswearde op it display.
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.
