5. Stiùireadh Obrachaidh

This section details how to use the Cyeelves Digital Multimeter VC830L for various electrical measurements.

5.1. Tomhas Meud DCtage (V–)

Gus tomhas DC voltage, such as from batteries or DC power supplies:

1. Suidhich an suidse rothlach chun an DC Vol a tha thu ag iarraidhtage (V–) range (e.g., 20V, 200V, 600V). Choose a range higher than the expected voltage.
2. Ceangail luaidhe an deuchainn dhubh ris an COIM Seumas agus an luaidhe deuchainn dearg chun an VumA seac.
3. Connect the test leads in parallel across the component or circuit to be measured. The red lead connects to the positive side, and the black lead to the negative side.
4. Leugh an voltage value on the LCD display. If a negative sign appears, the polarity of the test leads is reversed.
