5. Lietošanas instrukcijas

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

5.1. Measuring DC Voltage (V–)

Lai izmērītu DC tilptage, such as from batteries or DC power supplies:

1. Iestatiet rotācijas slēdzi uz vēlamo līdzstrāvas tilpumu.tage (V–) range (e.g., 20V, 200V, 600V). Choose a range higher than the expected voltage.
2. Savienojiet melno testa vadu ar COM ligzdu un sarkano testa vadu pie VΩmA džeks.
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. Izlasiet sējtage value on the LCD display. If a negative sign appears, the polarity of the test leads is reversed.

5.1.1. attēls: DC sējtage Mērīšana

This image shows the multimeter actively measuring DC voltage from a battery, with the display showing a reading of 0.98V. The test leads are correctly connected to the battery terminals.

5.2. Maiņstrāvas mērīšana Voltage (V∼)

Lai izmērītu maiņstrāvas tilpumutage, such as from wall outlets:

1. Iestatiet rotācijas slēdzi uz vēlamo maiņstrāvas skaļumu.tage (V∼) range (e.g., 200V, 600V). Choose a range higher than the expected voltage.
