5. Opsætning

5.1 Batteriinstallation

The DMMW3 uses one CR2032 coin cell battery. If the low battery indicator appears on the display, or if the unit does not power on, replace the battery:

1. Ensure the multimeter is powered off and disconnect all test leads.
2. Find batterirummet på bagsiden af ​​enheden.
3. Use a small screwdriver to open the battery compartment cover.
4. Remove the old CR2032 battery, noting its polarity.
5. Indsæt et nyt CR2032-batteri med den positive (+) side opad.
6. Sæt batterirummets dæksel på igen og fastgør det med skruen.

5.2 Tilslutning af testledninger

Always connect the test leads correctly for accurate and safe measurements:

• Indsæt den sorte testledning i KOM (Fælles) indgangsstik.
• Indsæt den røde testledning i VΩHz%mA input jack for most measurements (voltage, resistance, continuity, diode, capacitance, frequency, current up to 200mA).

6. Betjeningsvejledning

6.1 Tænd/sluk

To power on the multimeter, rotate the Function Selector Dial from the OFF position to any desired measurement function. To power off, rotate the dial back to the OFF position (indicated by the power symbol ⏻).

6.2 Funktionsvalg

Rotate the Function Selector Dial to choose the primary measurement category:

• mA: For measuring DC or AC current (up to 200mA).
• Ω / Continuity / Diode / Capacitance: For measuring resistance, checking continuity, testing diodes, or measuring capacitance. Use the MODE button to cycle through these functions.
• V: For measuring DC or AC voltage. Brug MODE button to switch between DC and AC voltage.
• Hz %: For measuring frequency or duty cycle. Use the MODE button to switch between frequency (Hz) and duty cycle (%).

6.3 Using Control Buttons

• KØRSELSVEJLEDNING: Press to select secondary functions within a dial position (e.g., AC/DC, Resistance/Continuity/Diode/Capacitance, Hz/%).
• RÆKKEVIDDE: Tryk for at skifte mellem automatisk og manuel områdeindstilling. Tryk gentagne gange på tast for at gennemgå de tilgængelige områder i manuel områdeindstilling.
• HOLDE: Tryk for at fryse den aktuelle aflæsning på displayet. Tryk igen for at slippe.
• MAKS: Press to capture and display the maximum value measured during a session. Press again to exit MAX mode.

6.4 Performing Measurements (Examplæs)

Always ensure the circuit is de-energized before connecting test leads for resistance, continuity, diode, or capacitance measurements.

6.4.1 DC/AC Voltage Måling

1. Set the Function Selector Dial to V.
2. Tryk på MODE button to select DC or AC voltage (DC or AC indicator on display).
3. Connect the red test lead to the positive (+) side of the circuit and the black test lead to the negative (-) side or ground.
4. Læs bindtage -værdi på displayet.

6.4.2 Modstandsmåling

1. Sørg for, at kredsløbet er spændingsløst.
2. Set the Function Selector Dial to Ω. Trykke MODE until the Ω symbol is displayed.
3. Tilslut testledningerne på tværs af den komponent, der skal måles.
4. Læs modstandsværdien på displayet.

6.4.3 Kontinuitetstest

1. Sørg for, at kredsløbet er spændingsløst.
2. Set the Function Selector Dial to Ω. Trykke MODE until the continuity symbol (⧸) vises.
3. Tilslut testledningerne på tværs af kredsløbet eller komponenten.
4. A continuous beep indicates continuity (low resistance). The display will show the resistance value.

7. Vedligeholdelse

7.1 Rengøring

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

7.2 Udskiftning af batteri

Refer to Section 5.1 for detailed battery replacement instructions. Always use a fresh CR2032 battery.

7.3 Udskiftning af sikringer

The DMMW3 has a 200mA MAX FUSED input for current measurements. If the current measurement function stops working, the fuse may need replacement. This procedure should only be performed by qualified personnel.

1. Ensure the multimeter is powered off and disconnect all test leads.
2. Open the back casing of the multimeter (this may require removing multiple screws).
3. Locate the fuse.
4. Replace the blown fuse with a fuse of the exact same type and rating (e.g., 200mA, fast-acting).
5. Carefully reassemble the multimeter, ensuring all screws are tightened.

WARNING: Using an incorrect fuse type or rating can damage the meter and pose a serious safety hazard.

7.4 Opbevaring

If the meter is not to be used for an extended period, remove the battery to prevent leakage. Store the meter in a cool, dry place, away from direct sunlight and extreme temperatures.
