2. Sikkerhedsoplysninger

Always adhere to safety precautions when using any electrical testing equipment. Failure to do so may result in electric shock, injury, or damage to the meter or equipment under test.

• Ensure the multimeter is in good working condition before use. Inspect test leads for damage.
• Anvend ikke voltage or current that exceeds the maximum rated values for the meter. This meter is rated for 600V.
• Always disconnect power to the circuit before connecting or disconnecting test leads, especially when measuring current or resistance.
• Vær forsigtig, når du arbejder med voltagover 30V AC RMS, 42V peak eller 60V DC, da disse udgør en risiko for stød.
• Ensure the function switch is set to the correct range before making measurements.
• Brug ikke måleren, hvis batteridækslet ikke er lukket korrekt.
• Udskift batterierne med det samme, når indikatoren for lavt batteri vises, for at sikre nøjagtige aflæsninger.

4. Opsætning

4.1 Batteriinstallation

The Ingco DM2002 requires alkaline batteries for operation. Ensure the correct polarity when inserting batteries.

1. Find batterirummet på bagsiden af ​​multimeteret.
2. Brug en skruetrækker til at åbne batteridækslet.
3. Insert the required alkaline batteries, observing the polarity markings (+ and -).
4. Sæt batterirummets dæksel på igen og fastgør det med skruen.

4.2 Tilslutning af testledninger

Korrekt tilslutning af testledninger er afgørende for nøjagtige og sikre målinger.

• Sæt den sorte testledning i 'COM' (Common) indgangsstikket.
• For de fleste målinger (volumentage, resistance, capacitance, frequency, temperature, and small currents), insert the red test lead into the 'VΩmA' input jack.
• For measuring large currents (up to 10A), insert the red test lead into the '10A' input jack. Ensure the function switch is set to the appropriate current range.

5. Betjeningsvejledning

Before taking any measurement, ensure the test leads are correctly connected and the function switch is set to the desired measurement mode.

5.1 Måling af AC/DC Voltage (V~ / V-)

1. Tilslut den sorte testledning til 'COM' og den røde testledning til 'VΩmA'.
2. Set the function switch to the desired AC Voltage (V~) eller DC Voltage (V-) rækkevidde.
3. Tilslut testproberne parallelt på tværs af den komponent eller det kredsløb, der skal måles.
4. Læs bindtage -værdi på LCD -displayet.

5.2 Measuring AC/DC Current (A~ / A-)

Forsigtighed: Tilslut aldrig multimeteret parallelt med et voluminiumtage source when measuring current, as this can damage the meter and pose a safety risk.

1. Connect the black test lead to 'COM'.
2. For currents up to 200mA, connect the red test lead to 'VΩmA'. For currents up to 10A, connect the red test lead to '10A'.
3. Set the function switch to the desired AC Current (A~) or DC Current (A-) range.
4. Open the circuit where the current is to be measured and connect the multimeter in series with the circuit.
5. Aflæs den aktuelle værdi på LCD-displayet.

5.3 Måling af modstand (Ω)

1. Sørg for, at kredsløbet er spændingsløst, før du måler modstanden.
2. Tilslut den sorte testledning til 'COM' og den røde testledning til 'VΩmA'.
3. Set the function switch to the desired Resistance (Ω) range.
4. Tilslut testproberne på tværs af den komponent, der skal måles.
5. Aflæs modstandsværdien på LCD-displayet.

5.4 Måling af kapacitans (F)

1. Sørg for, at kondensatoren er helt afladet før måling for at forhindre beskadigelse af måleren.
2. Tilslut den sorte testledning til 'COM' og den røde testledning til 'VΩmA'.
3. Set the function switch to the Capacitance (F) range.
4. Tilslut testproberne på tværs af kondensatorterminalerne.
5. Aflæs kapacitansværdien på LCD-displayet.

5.5 Measuring Frequency (Hz) and Temperature (°C/°F)

Refer to the specific markings on the rotary switch for Frequency (Hz) and Temperature (°C/°F) functions. The connection method for these measurements typically involves the 'COM' and 'VΩmA' jacks, often requiring a dedicated temperature probe for temperature measurements (not included with all multimeters).

5.6 HOLD-funktion

Press the 'HOLD' button to freeze the current reading on the LCD display. Press it again to release the hold and resume live readings.

6. Vedligeholdelse

6.1 Rengøring

Tør målerens c afasing med annonceamp klud og mildt rengøringsmiddel. Brug ikke slibemidler eller opløsningsmidler. Sørg for, at måleren er tør før brug.

6.2 Udskiftning af batteri

When the low battery indicator appears on the display, replace the batteries as described in Section 4.1. Always use new alkaline batteries of the specified type.

6.3 Udskiftning af sikringer

If the current measurement function stops working, the fuse may need replacement. This typically requires opening the meter's casing. Refer to the meter's internal markings for the correct fuse type and rating (e.g., 200mA/250V for mA range, 10A for 10A range). Only replace with a fuse of the identical type and rating.

6.4 Opbevaring

Hvis måleren ikke bruges i længere tid, skal batterierne fjernes for at forhindre lækage og beskadigelse. Opbevar måleren et køligt og tørt sted, væk fra direkte sollys og ekstreme temperaturer.

7. Fejlfinding

• Ingen visning / Svag visning: Check battery installation. Replace batteries if low battery indicator is present or if display is faint.
• Forkerte aflæsninger: Ensure the function switch is set to the correct range. Check test lead connections. Verify the circuit is properly connected.
• Strømmåling virker ikke: Check the fuse. Replace if blown (refer to Section 6.3).
• 'OL' or '1' on Display: Indicates overload or out-of-range measurement. Select a higher range or verify circuit connection.
