3.2 Tilslutning af testledninger

For de fleste målinger (volumentage, resistance, capacitance, diode, continuity), connect the test leads as follows:

• Indsæt den sorte testledning i KOM (fælles) indgangsstik.
• Indsæt den røde testledning i VΩ+ indgangsstik.

For temperature measurements, connect the temperature probe to the KOM og T- indgangsstik.

4. Betjeningsvejledning

Before any measurement, ensure the meter is set to the correct function and range. Always observe safety precautions.

4.1 Tænd/sluk

Turn the rotary switch from the OFF position to any desired measurement function to power on the meter. To power off, turn the rotary switch back to the OFF position.

4.2 AC/DC Voltage Måling

1. Drej drejekontakten til V~ (AC-volumentage) eller V- (DC bindtage) stilling.
2. Connect the test leads to the circuit in parallel with the load or power source.
3. Læs bindtage value on the LCD display. The meter will automatically select the appropriate range.
