6.2 Tilslutning af testledninger

For bdtage, resistance, capacitance, frequency (V), diode, and continuity measurements, connect the test leads:

• Sæt den sorte testledning i "COM" (fælles) indgangsstikket.
• Insert the red test lead into the "VΩHz" input jack.

7. Betjeningsvejledning

To operate the clamp meter, turn the rotary switch to the desired function. The meter will automatically select the appropriate range unless manual ranging is activated.

7.1 AC/DC strømmåling (Clamping)

For at måle AC- eller DC-strøm skal du bruge cl-knappen.amp kæbe:

1. Turn the rotary switch to the "A~" (AC Current) or "A=" (DC Current) position.
2. Åbn clamp kæben ved at trykke på aftrækkeren.
3. Enclose only one conductor (wire) of the circuit within the clamp kæbe. Sørg for, at kæben er helt lukket.
4. Aflæs den aktuelle værdi på displayet.
5. For DC current, the MS2138R model features a DCA automatic zero return key for accurate readings.

7.2 AC/DC Voltage Måling

Til at måle AC eller DC voltage:

1. Tilslut testledningerne som beskrevet i afsnit 6.2.
2. Drej drejekontakten til "V~" (AC-volumen)tage) eller "V=" (DC-volumentage) stilling.
3. Touch the red test lead to the positive side of the circuit and the black test lead to the negative side (or neutral/ground for AC).
4. Læs bindtage -værdi på displayet.

7.3 Modstandsmåling

Sådan måles modstand:
