2. Sikkerhedsoplysninger

Always observe basic safety precautions when using this multimeter to avoid electric shock, injury, or damage to the meter or equipment under test. Pay particular attention to all warnings and cautions.

• Anvend ikke voltage to the meter when the function switch is set to Resistance, Capacitance, or Inductance mode.
• Ensure the test leads are correctly inserted into the appropriate jacks for the desired measurement.
• Afbryd altid strømmen til kredsløbet og aflade alle højspændingsledninger.tage capacitors before measuring resistance, capacitance, or inductance.
• 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. Opsætning

4.1 Batteriinstallation

Multimeteret kræver et 9V batteri (medfølger). Sådan installeres eller udskiftes batteriet:

1. Find batterirummet på bagsiden af ​​måleren.
2. Use the included screwdriver to remove the screw securing the battery cover.
3. Insert the 9V battery, observing correct polarity.
4. Sæt batteridækslet på igen og fastgør det med skruen.

4.2 Tilslutning af testledninger

Connect the red and black test leads to the appropriate input jacks on the multimeter. The black lead typically connects to the 'COM' (common) jack, and the red lead connects to the jack corresponding to the desired measurement function (e.g., VΩmA for voltage, resistance, or small current measurements).

5. Betjeningsvejledning

5.1 Tænd/sluk

Tryk på MAGT button to turn the multimeter on. To turn it off, press the MAGT button again or wait for the auto-off function to activate.

5.2 Capacitance Measurement (C)

The GC-4070L can measure capacitance from 2000pF to 200µF.

1. Rotate the function switch to the desired 'C' (Capacitance) range (e.g., 2000pF, 20nF, 200nF, 2µF, 20µF, 200µF).
2. Vigtig: Before measuring, ensure the capacitor is fully discharged to avoid damage to the meter.
3. Connect the test leads to the capacitor terminals. The reading will appear on the LCD display.

5.3 Inductance Measurement (L)

The GC-4070L can measure inductance from 20mH to 20H.

1. Rotate the function switch to the desired 'L' (Inductance) range (e.g., 20mH, 200mH, 2H, 20H).
2. Connect the test leads to the inductor terminals. The reading will appear on the LCD display.

5.4 Modstandsmåling (Ω)

The GC-4070L can measure resistance from 20Ω to 2000MΩ.

1. Rotate the function switch to the desired 'Ω' (Resistance) range (e.g., 20Ω, 200Ω, 2kΩ, 20kΩ, 200kΩ, 2MΩ, 20MΩ, 200MΩ, 2000MΩ).
2. Connect the test leads to the resistor terminals. The reading will appear on the LCD display.

5.5 hFE Test

The hFE test function allows for testing of transistor gain.

1. Rotate the function switch to the 'hFE' position.
2. Insert the transistor leads into the appropriate sockets on the meter (E, B, C for Emitter, Base, Collector, and PNP/NPN type).
3. The hFE value will be displayed on the LCD.

5.6 Backlight and Auto-Off

• Baggrundsbelysning: Tryk på Baggrundsbelysning button to illuminate the LCD display. Press it again to turn off the backlight.
• Auto-sluk: Måleren slukker automatisk efter cirka 10 minutters inaktivitet for at spare batterilevetid.

6. Vedligeholdelse

• Rensning: Tør måleren af ​​med en tør, blød klud. Brug ikke slibemidler eller opløsningsmidler.
• Udskiftning af batteri: Replace the 9V battery as described in Section 4.1 when the low battery indicator appears on the display.
• Opbevaring: If the meter is not used for a long period, remove the battery to prevent leakage and damage. Store in a cool, dry place.

7. Fejlfinding

• Ingen visning: Kontroller batteriinstallationen, og sørg for, at batteriet har tilstrækkelig opladning.
• Forkerte aflæsninger: Verify that the function switch is set to the correct range and that test leads are properly connected. Ensure the component under test is correctly prepared (e.g., discharged capacitors).
• "OL" or "1" on Display: This indicates an overload or out-of-range measurement. Select a higher range or check the circuit.
