4. Opsætning

4.1 Batteriinstallation

The multimeter is powered by 2 x AAA 1.5V batteries. To install or replace batteries:

1. Sørg for, at multimeteret er slukket, og at alle testledninger er frakoblet.
2. Find batteridækslet på bagsiden af ​​enheden.
3. Skru fastholdelsesskruen(e) af, og fjern dækslet.
4. Insert the 2 x AAA 1.5V batteries, observing the correct polarity (+ and -) as indicated inside the compartment.
5. Sæt dækslet til batterirummet på igen, og fastgør det med skruen/skruerne.

Enheden har lav lydstyrketage display indicator to alert you when batteries need replacement.

4.2 Tilslutning af testledninger

For de fleste målinger (volumentage, resistance, capacitance, frequency, temperature, diode, continuity), insert the red test lead into the 'VΩHz' jack and the black test lead into the 'COM' (common) jack. For current measurements up to 10A, insert the red test lead into the '10A' jack and the black test lead into the 'COM' jack.

5. Betjeningsvejledning

Turn the rotary switch to the desired measurement function. The multimeter features auto-ranging for most functions, simplifying operation.

5.1 DC/AC Voltage Måling

Select 'V~' for AC voltage eller 'V=' for DC-volumentage. Tilslut testledningerne parallelt til det kredsløb eller den komponent, du ønsker at måle.

5.2 DC/AC Current Measurement

Select 'A~' for AC current or 'A=' for DC current. Connect the test leads in series with the circuit. For currents up to 10A, use the '10A' jack for the red lead. Ensure the circuit is de-energized before connecting the multimeter in series.

5.3 Modstandsmåling

Select 'Ω'. Connect the test leads across the component to measure its resistance.

5.4 Kapacitansmåling

Select 'F'. Connect the test leads across the capacitor to measure its capacitance. Ensure the capacitor is discharged before testing.

5.5 Frekvensmåling

Select 'Hz'. Connect the test leads to the signal source to measure its frequency.

5.6 Temperaturmåling

Select 'TEMP'. Connect the temperature probe to the appropriate jacks (usually 'VΩHz' and 'COM'). Place the probe in contact with the object whose temperature you wish to measure.

5.7 NCV-funktion (kontaktfri volumen)tage)

Rotate the dial to 'NCV'. Hold the top part of the multimeter near an AC voltage source (e.g., an electrical outlet or live wire). The display will show flickering lines (1 short line for low voltage, 4 short lines for high voltage) and an alarm will sound if AC voltage er opdaget.

5.8 Kontinuitetstest

Select 'Ω' and press the 'SELECT' button to cycle through functions until the continuity symbol (a speaker icon) is displayed. Connect the test leads across the circuit or component. An alarm will sound if the resistance is less than 50Ω, indicating continuity.

5.9 Diodetest

Select 'Ω' and press the 'SELECT' button to cycle through functions until the diode symbol is displayed. Connect the test leads across the diode to test its forward voltage drop.

5.10 Datahold

Press the 'HOLD' button to freeze the current reading on the display. Press it again to release the hold function.

5.11 Lommelygte og baggrundsbelysning

Press the backlight button (often labeled with a light bulb icon or combined with 'HOLD') to activate the flashlight and display backlight. The backlight automatically turns off after 15 seconds to save power.

5.12 Max/Min funktion

Press the 'MAX/MIN' button to enter Max/Min recording mode. The multimeter will continuously record the maximum and minimum values detected. Press again to cycle between MAX, MIN, and current readings.

5.13 Relative Value Measurement

Press the 'RELA' button to enter relative measurement mode. This function subtracts the current reading from subsequent readings, showing the difference.

5.14 Automatisk slukning

The multimeter will automatically power off after approximately 15 minutes of inactivity to conserve battery life. To disable this feature temporarily, refer to the full user manual (if provided) or specific product documentation.

7. Vedligeholdelse

7.1 Rengøring

Tør multimeteret c afasing with a dry, soft cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these may damage the plastic or electronic components.

7.2 Udskiftning af batteri

When the low battery indicator appears on the display, replace the 2 x AAA 1.5V batteries promptly. Always ensure the device is turned off and all test leads are disconnected before opening the battery compartment. Dispose of old batteries responsibly according to local regulations.

7.3 Opbevaring

Store the multimeter in a cool, dry place away from direct sunlight, extreme temperatures, and high humidity. If storing for an extended period, it is advisable to remove the batteries to prevent leakage.

8. Fejlfinding

• Ingen skærm/strøm: Check if the batteries are correctly installed and charged. Replace the 2 x AAA 1.5V batteries if the low voltage indicator is present or if the device does not power on.
• Forkerte aflæsninger: Ensure that the test leads are securely connected to the correct input jacks for the desired measurement. Verify that the rotary switch is set to the appropriate function and range. Inspect test leads for any damage or breaks.
• Ingen biplyd ved kontinuitet: Confirm that the continuity function is selected (speaker icon). If the resistance of the circuit or component is above 50Ω, the beep will not sound.
• NCV registrerer ikke volumentage: Ensure the NCV function is selected. Hold the multimeter's NCV sensor (usually at the top) close enough to the AC voltage kilde.
• Display Shows "OL": This indicates an over-range condition. The measured value exceeds the maximum range of the selected function. Try switching to a higher range if available, or ensure the measurement is within the device's capabilities.

9. Brugertips

• For accurate temperature readings, ensure the temperature probe is properly connected and in good contact with the object being measured. Allow a few moments for the reading to stabilize.
• Utilize the built-in flashlight feature in dimly lit environments for better visibility of test points and to ensure safe and accurate probe placement.
• While the multimeter has an auto-power-off feature, manually turning off the device when not in use can further conserve battery life, especially during short breaks.
• Start altid med det højeste område, når du måler et ukendt volumen.tage or current to prevent damage to the multimeter, then adjust downwards if necessary.
