2. Sikkerhedsoplysninger

Advarsel: To avoid electrical shock or personal injury, read all safety information before using this product. Use the product only as specified in this manual, or the protection provided by the product may be impaired.

• Sørg altid for, at måleren er i den korrekte funktion og det korrekte område, før du foretager målinger.
• Påfør ikke mere end den nominelle voltage, som markeret på måleren, mellem terminalerne eller mellem en hvilken som helst terminal og jord.
• Vær forsigtig, når du arbejder med voltagover 30V AC RMS, 42V peak eller 60V DC. Disse voluminertages udgør en stødfare.
• Før strømmåling skal du sørge for, at kredsløbet er spændingsløst, og at clamp jaws are properly closed around the conductor.
• Brug ikke måleren med batteridækslet åbent.
• Udskift batteriet med det samme, når indikatoren for lavt batteri vises.
• Frakobl altid testledningerne fra kredsløbet, før du skifter funktioner.
• Overhold alle lokale og nationale sikkerhedsforskrifter.

5. Opsætning

5.1 Batteriinstallation

1. Sørg for, at måleren er slukket.
2. Find batteridækslet på bagsiden af ​​måleren.
3. Brug en skruetrækker til at løsne skruen/skruerne, der fastgør batteridækslet.
4. Fjern batteridækslet.
5. Insert three AAA 1.5V batteries, observing the correct polarity (+ and -).
6. Sæt batteridækslet på igen, og spænd skruen/skruerne.

5.2 Tilslutning af testledninger

For bdtage, resistance, capacitance, frequency, duty cycle, diode, and continuity measurements:

• Insert the red test lead into the "INPUT" terminal.
• Insert the black test lead into the "COM" (common) terminal.

6. Betjeningsvejledning

6.1 Tænd/sluk

Rotate the function dial from the "OFF" position to any desired measurement function to turn the meter ON. To turn OFF, rotate the dial back to the "OFF" position.

6.2 Funktionsvalg

The large rotary dial allows selection of various measurement functions. Some positions on the dial may have multiple functions (e.g., AC voltage og DC voltage). Tryk på "SEL" knappen for at gennemgå disse funktioner.

6.3 AC/DC strømmåling (Clamp)

1. Rotate the function dial to the "A~" (AC-strøm) eller "A=" (DC-strøm) position.
2. Tryk på clamp aftrækkeren for at åbne kæberne.
3. Enclose a single conductor (not a power cord with multiple wires) within the clamp kæber. Sørg for, at kæberne er helt lukkede.
4. Læs den aktuelle værdi på LCD-skærmen.
5. For DC current, observe the polarity indicated on the display.

6.4 AC/DC Voltage Måling

1. Connect the red test lead to the "INPUT" terminal and the black test lead to the "COM" terminal.
2. Rotate the function dial to the "V~" (AC-volumentage) eller "V=" (DC bindtage) position. Use the "SEL" knappen om nødvendigt.
3. Tilslut testledningerne parallelt til det kredsløb eller den komponent, der testes.
4. Læs bindtage-værdi på LCD-skærmen.

6.5 Resistance, Capacitance, Frequency, Duty Cycle, Diode, and Continuity

For these measurements, connect the test leads as described in Section 5.2. Rotate the function dial to the appropriate position and use the "SEL" button to select the specific function if multiple are available on one dial position.

• Modstand (Ω): Sørg for, at kredsløbet er spændingsløst, før du måler modstanden.
• Kapacitans (F): Discharge capacitors before measurement.
• Frekvens (Hz) / Duty Cycle (%): Forbind på tværs af signalkilden.
• Diode test (→|): Connect the red lead to the anode and black lead to the cathode.
• Kontinuitetstest ()))): A built-in buzzer will sound if the resistance is below approximately 50Ω.

6.6 Specialfunktioner

• "HOLDE" Button: Press to freeze the current reading on the display. Press again to release.
• "MAKS/MIN" Button: Press to enter MAX/MIN recording mode. The meter will display the maximum or minimum value measured since entering the mode. Press again to cycle between MAX, MIN, and current reading. Hold to exit.
• "REL" (Relative) Button: Press to store the current reading as a reference value. Subsequent measurements will be displayed as the difference from this reference. Press again to exit.
• Backlight/Clamp Lys: The backlight and clamp light can be activated for improved visibility in low-light conditions. Refer to the specific button on the meter (often combined with another function or a dedicated light button).

7. Vedligeholdelse
