- Håndbeskyttelse: Provides protection against accidental contact.
4. Opsætning
4.1 Batteriinstallation
The PeakTech P 3131 requires two 1.5V AAA batteries (included). To install or replace batteries:
- Sørg for, at enheden er slukket.
- Find batteridækslet på bagsiden af måleren.
- Brug en skruetrækker til at åbne rummet.
- Insert the two AAA batteries, observing correct polarity (+ and -).
- Sæt batterirummets dæksel på igen og fastgør det med skruen.
When the low battery indicator appears on the display, replace the batteries immediately to ensure accurate measurements.
4.2 Tilslutning af testledninger
For bdtage, resistance, and continuity measurements, connect the supplied test leads:
- Indsæt den sorte testledning i KOM (common) input terminal.
- Indsæt den røde testledning i VΩ indgangsterminal.

5. Betjeningsvejledning
5.1 Tænd/sluk
Rotate the function selector dial from the "OFF" position to any desired measurement function to power on the meter. To power off, rotate the dial back to "OFF". The meter features an automatic power-off function (can be deactivated) to conserve battery life.
5.2 AC/DC strømmåling (Clamp)
To measure current without breaking the circuit:
- Drej funktionsvælgeren til A~ (AC-strøm) eller A= (DC-strøm) position.
- Tryk på AC/DC button if you need to switch between AC and DC current modes (if the dial position combines them).
- Tryk på NUL button to zero the display before measuring DC current, especially for small currents, to compensate for residual magnetism.
- Åbn clamp kæben ved at trykke på aftrækkeren.
- Enclose only en conductor with the clamp kæbe. Sørg for, at kæben er helt lukket.
- Aflæs den aktuelle værdi på LCD-displayet.

5.3 AC/DC Voltage Måling
At måle voltage:
- Tilslut testledningerne som beskrevet i afsnit 4.2.
- Drej funktionsvælgeren til V~ (AC-volumentage) eller V= (DC bindtage) stilling.
- Tilslut testproberne parallelt til det kredsløb eller den komponent, du ønsker at måle.
- Læs bindtage -værdi på LCD -displayet.
5.4 Modstands- og kontinuitetsmåling
To measure resistance or check for continuity:
- Tilslut testledningerne som beskrevet i afsnit 4.2.
- Drej funktionsvælgeren til Ω/))) (Resistance/Continuity) position.
- For resistance: Connect the test probes across the component. Ensure the circuit is de-energized.
- For continuity: Touch the test probes to the two points you want to check. A continuous beep indicates a low-resistance path (continuity).
- Aflæs modstandsværdien på LCD-displayet.
5.5 Specialfunktioner
- Ægte RMS: The meter measures True Root Mean Square values for AC voltage and current, providing accurate readings for non-sinusoidal waveforms.
- Datahold (H): Tryk på H/MAX Tryk kortvarigt på knappen for at fryse den aktuelle aflæsning på displayet. Tryk igen for at slippe.
- Maximum Value Hold (MAX): Tryk og hold på H/MAX button to capture and display the maximum measured value. Press again to exit.
- NUL-funktion: Used to zero the display for DC current measurements to eliminate offset errors.
- Automatisk afstandsmåling: The meter automatically selects the appropriate measurement range.
- Automatisk sluk: The meter automatically turns off after a period of inactivity to save battery. This feature can typically be disabled by holding a specific button during power-on (refer to the device's on-screen indicators or a more detailed manual if available).
6. Vedligeholdelse
6.1 Rengøring
Tør målerens hus af med enamp en klud og et mildt rengøringsmiddel. Brug ikke slibemidler eller opløsningsmidler. Sørg for, at måleren er helt tør før brug.
6.2 Udskiftning af batteri
Refer to Section 4.1 for instructions on battery replacement. Always use two fresh 1.5V AAA batteries. Remove batteries if the meter is not used for an extended period to prevent leakage.
