5. Betjeningsvejledning

Before taking any measurements, ensure the test leads are securely plugged into the correct input jacks.

5.1 Måling af DC Voltage (V=)

1. Sæt den røde testledning i VΩmA-stikket og den sorte testledning i COM-stikket.
2. Set the rotary switch to the desired DCV range (e.g., 200m, 2000m, 20, 200, 500). If the voltagHvis e er ukendt, skal du starte med det højeste område og sænke det efter behov.
3. Tilslut testproberne på tværs af den komponent eller det kredsløb, der skal måles.
4. Læs bindtage værdi på det digitale display.

5.2 Måling af AC Voltage (V~)

1. Sæt den røde testledning i VΩmA-stikket og den sorte testledning i COM-stikket.
2. Set the rotary switch to the desired ACV range (e.g., 200, 500). If the voltage is unknown, start with the highest range.
3. Tilslut testproberne på tværs af AC-volumentage kilde.
4. Læs bindtage værdi på det digitale display.

5.3 Måling af jævnstrøm (A=)

1. For currents up to 200mA: Sæt den røde testledning i VΩmA-stikket og den sorte testledning i COM-stikket.
2. For currents up to 10A: Insert the red test lead into the 10A jack and the black test lead into the COM jack. Caution: Do not measure more than 10 seconds every 10 minutes when using the 10A range.
3. Set the rotary switch to the desired DCA range (e.g., 2000µ, 20m, 200m, 10A).
