2. Sikkerhedsoplysninger

To ensure safe operation and to avoid damage to the meter, please read this manual carefully before use. Always adhere to the following safety precautions:

• Do not exceed the maximum input values for any measurement range.
• Udvis ekstrem forsigtighed, når du arbejder med voltagover 30V AC RMS, 42V peak eller 60V DC. Disse voluminertages udgør en stødfare.
• Before measuring resistance, capacitance, or inductance, ensure that the circuit under test is de-energized and all capacitors are discharged.
• Brug altid den korrekte funktion og det korrekte område til målinger.
• Undersøg testledningerne for skader før hver brug. Må ikke anvendes, hvis isoleringen er kompromitteret.
• Brug ikke måleren, hvis den ser beskadiget ud, eller hvis huset er åbent.
• Udskift batteriet, når indikatoren for lavt batteri vises, for at sikre nøjagtige aflæsninger.

4.2 Tilslutning af testledninger

Tilslut testledningerne til de relevante indgangsstik:

• Indsæt rød testledning ind i COM/LC+ jack for most measurements.
• Indsæt sort testledning ind i LC- jack for most measurements.
• For resistance measurements, the red lead connects to Ω and the black lead to COM/LC+.

5. Betjeningsvejledning

5.1 Tænd/sluk

Tryk på det røde MAGT button to turn the meter on. Press it again to turn the meter off.

5.2 Funktionsvalg

Rotate the central function switch to select the desired measurement mode (e.g., Capacitance 'C', Inductance 'L', Resistance 'Ω', or hFE).

5.3 Baggrundsbelysningsfunktion

Tryk på den blå Baggrundslys button to illuminate the LCD display. This feature is useful in dimly lit environments. Press it again to turn off the backlight.

5.4 Automatisk slukning

The meter is designed to automatically power off after approximately 10 minutes of inactivity to conserve battery life. To reactivate, press the MAGT knap.

5.5 Måleprocedurer

Always ensure the component or circuit is de-energized and discharged before connecting the test leads.

5.5.1 Capacitance Measurement (C)

1. Rotate the function switch to the desired capacitance range (e.g., 2000pF, 20nF, 200nF, 2uF, 20uF, 200uF).
2. Tilslut den røde testledning til COM/LC+ Jack og den sorte testledning til LC- stik.
3. Connect the test leads across the capacitor to be measured.
4. Aflæs kapacitansværdien på LCD-displayet.

5.5.2 Inductance Measurement (L)

1. Rotate the function switch to the desired inductance range (e.g., 20mH, 200mH, 2H, 20H).
2. Tilslut den røde testledning til COM/LC+ Jack og den sorte testledning til LC- stik.
3. Connect the test leads across the inductor to be measured.
4. Read the inductance value on the LCD display.

5.5.3 Modstandsmåling (Ω)

1. Rotate the function switch to the desired resistance range (e.g., 20Ω, 200Ω, 2KΩ, 20KΩ, 200KΩ, 2MΩ, 20MΩ, 200MΩ, 2000MΩ).
2. Tilslut den røde testledning til Ω Jack og den sorte testledning til COM/LC+ stik.
3. Connect the test leads across the resistor or circuit to be measured.
4. Aflæs modstandsværdien på LCD-displayet.

5.5.4 hFE Test (Transistor Test)

1. Drej funktionskontakten til hFE position.
2. Identificer om transistoren er NPN eller PNP.
3. Insert the transistor's emitter (E), base (B), and collector (C) leads into the corresponding holes in the hFE socket on the meter.
4. Read the hFE value (DC current gain) on the LCD display.
