This device is designed for measuring various electrical parameters, including voltage, current, and resistance. Please read this manual thoroughly before use to ensure proper functionality and to prevent potential hazards.

Sikkerhedsoplysninger

Always adhere to the following safety precautions to avoid electric shock or damage to the multimeter:

• Overskrid ikke de maksimale inputværdier, der er angivet for hver funktion.
• Udvis ekstrem forsigtighed, når du arbejder med voltages over 60V DC eller 30V AC RMS.
• Ensure test leads are in good condition and properly seated before making measurements.
• Never connect the multimeter to a voltage source when the function switch is set to current, resistance, or diode/continuity test.
• Replace the battery immediately when the low battery indicator appears.
• Do not operate the multimeter if it appears damaged or if the case is open.

• Drejekontakt: Selects measurement functions and ranges.
• Indgangsstik: Connect test leads for various measurements.
  • COM Jack: Fælles (negativ) indgang for alle målinger.
  • VΩmA Jack: Positiv indgang for volumentage, resistance, and small current measurements.
  • 10A Jack: Positive input for high current (up to 10A) measurements.
• Prøveemner: Red and black probes for connecting to circuits.
• Hylster: Beskyttende casing for the multimeter.

Opsætning

1. Batteriinstallation

The multimeter requires a 9V battery (not always included). To install or replace the battery:

1. Ensure the multimeter is turned OFF and disconnect all test leads.
2. Find batteridækslet på bagsiden af ​​enheden.
3. Remove the screw(s) securing the cover and carefully lift it off.
4. Connect a new 9V battery to the battery clip, observing correct polarity.
5. Placer batteriet i batterirummet, og sæt dækslet på igen, og fastgør det med skruen/skruerne.

2. Tilslutning af testledninger

For most measurements, connect the test leads as follows:

• Indsæt den sorte testledning i KOM (common) jack.
• Indsæt den røde testledning i VΩmA jack for voltage, resistance, and low current measurements.
• For målinger af høj strøm (op til 10 A), sæt den røde testledning i 10A stik.

Betjeningsvejledning

Before taking any measurement, ensure the test leads are correctly connected and the rotary switch is set to the appropriate function and range.

1. Measuring DC Voltage (V–)

1. Connect the red lead to the VΩmA Knægt og sort fører til KOM stik.
2. Set the rotary switch to the desired DC Voltage (V–) range (e.g., 20V, 200V). If the voltage is unknown, start with the highest range and decrease as needed.
3. Tilslut testproberne på tværs af den komponent eller det kredsløb, der skal måles.
4. Læs bindtage værdi på det digitale display.

2. Måling af AC Voltage (V∼)

1. Connect the red lead to the VΩmA Knægt og sort fører til KOM stik.
2. Set the rotary switch to the desired AC Voltage (V∼) range (e.g., 200V, 750V).
3. Tilslut testproberne på tværs af AC-volumentage kilde.
4. Læs bindtage værdi på det digitale display.

3. Measuring DC Current (A–)

1. For currents up to 200mA, connect the red lead to the VΩmA jack. For currents up to 10A, connect the red lead to the 10A jack. Connect the black lead to the KOM stik.
2. Set the rotary switch to the desired DC Current (A–) range (e.g., 200mA, 10A).
3. Vigtig: To measure current, the multimeter must be connected in series with the circuit. Break the circuit and insert the multimeter.
4. Aflæs den aktuelle værdi på det digitale display.

4. Måling af modstand (Ω)

1. Connect the red lead to the VΩmA Knægt og sort fører til KOM stik.
2. Set the rotary switch to the desired Resistance (Ω) range (e.g., 200Ω, 2kΩ).
3. Sørg for, at kredsløbet eller komponenten er spændingsløs, før du måler modstanden.
4. Tilslut testproberne på tværs af komponenten.
5. Aflæs modstandsværdien på det digitale display.

5. Diode og kontinuitetstest

1. Connect the red lead to the VΩmA Knægt og sort fører til KOM stik.
2. Set the rotary switch to the Diode/Continuity symbol (often a diode symbol and a sound wave symbol).
3. For Diode Test: Connect the red probe to the anode and the black probe to the cathode. The display will show the forward voltage drop. Reverse the probes; the display should show 'OL' (Open Loop) for a good diode.
4. Til kontinuitetstest: Connect the probes across the circuit or component. If there is continuity (low resistance), the multimeter will emit an audible beep.

Opretholdelse

Rensning

Tør sagen af ​​med annonceamp cloth and mild detergent. Do not use abrasives or solvents. Keep the input terminals free from dirt and moisture.

Udskiftning af batteri

Refer to the "Battery Installation" section under Setup. Replace the 9V battery when the low battery indicator appears on the display to ensure accurate readings.

Udskiftning af sikring

If the current measurement function stops working, the fuse may need replacement. This typically requires opening the multimeter case. Refer to the specifications for the correct fuse type and rating. If unsure, consult a qualified technician.
