2.2 Testa vadu pievienošana
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.
- Lielākajai daļai tilpumatage, 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, pretestība un miliampšeit strāvas mērījumi.
- 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. Līdzstrāvas mērīšana 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.
- Izlasiet sējtage vērtība displejā.
3.2. Maiņstrāvas mērīšana 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.
- Pievienojiet testa vadus maiņstrāvas spriegumamtage source. Polarity does not matter for AC voltage.
- Izlasiet sējtage vērtība displejā.
3.3 Pretestības (Ω) mērīšana
- Pirms pretestības mērīšanas pārliecinieties, vai ķēde vai komponents ir atvienots no strāvas.
- Set the rotary dial to the desired Ω range (e.g., 200, 2K, 20K, 200K, 2M, 20M, 200M).
- Pievienojiet testa vadus mērāmajai sastāvdaļai.
- Displejā nolasiet pretestības vērtību.
3.4 Measuring DC Current (DCA)
- Pārliecinieties, ka ķēde ir atvienota no strāvas.
- Set the rotary dial to the desired DCA range (e.g., 200µ, 2m, 20m, 200m, 10A).
- Svarīgi: 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)
- Pārliecinieties, ka ķēde ir atvienota no strāvas.
- Set the rotary dial to the desired ACA range (e.g., 200µ, 2m, 20m, 200m, 10A).
- Svarīgi: 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.
- Re-energize the circuit and read the current value.
3.6 Measuring Capacitance (CX)
- Pirms testēšanas pārliecinieties, vai kondensators ir pilnībā izlādējies.
- Set the rotary dial to the CX range (e.g., 2n, 20n, 200n, 2µ, 20µ).
- Pievienojiet testa vadus kondensatora spailēm.
- Displejā nolasiet kapacitātes vērtību.
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.
4. Apkope
4.1. Akumulatora nomaiņa
Replace the 9V 006P battery when the low battery indicator appears on the display or if the multimeter fails to power on. Follow the instructions in Section 2.1.
