2. Produktet er slutview
The Klein Tools MM1300 is an auto-ranging digital multimeter designed for electricians and HVAC professionals. It measures a comprehensive range of electrical parameters, including AC/DC voltage, AC/DC current, resistance, capacitance, frequency, duty cycle, and temperature. It also features diode and continuity testing capabilities.

Figur 1: Forside view of the Klein Tools MM1300 Multimeter. The display shows '6.000 V', indicating a voltage measurement. Below the display are function buttons (RELΔ, RANGE, MAX/MIN, AUTOHOLD, SELECT) and a rotary dial for selecting measurement modes. The input jacks for test leads are located at the bottom.
Key features include a backlit display for visibility in various lighting conditions, and it comes with a Klein case, thermocouple, test leads, and batteries.
3. Opsætning
3.1 Batteriinstallation
The MM1300 requires two AAA batteries (included). To install or replace batteries:
- Sørg for, at måleren er SLUKKET, og frakobl alle testledninger.
- Find batteridækslet på bagsiden af måleren.
- Skru fastholdelsesskruen(e) af, og fjern dækslet.
- Insert two AAA batteries, observing correct polarity (+/-).
- Sæt dækslet til batterirummet på igen, og fastgør det med skruen/skruerne.
3.2 Tilslutning af testledning
Korrekt tilslutning af testledninger er afgørende for nøjagtige og sikre målinger.
- For de fleste volumenertage, resistance, continuity, diode, capacitance, frequency, and temperature measurements, connect the black test lead to the KOM stik og den røde testledning til VΩHz→⊤Temp stik.
- For current measurements up to 400mA, connect the black test lead to the KOM stik og den røde testledning til mAmA stik.
- For current measurements up to 10A, connect the black test lead to the KOM stik og den røde testledning til A stik.
4. Betjeningsvejledning
4.1 Tænd/sluk
Turn the rotary dial from the OFF position to any desired measurement function to power on the meter. To power off, turn the rotary dial back to the SLUKKET position.
4.2 Funktionsvalg
The rotary dial selects the primary measurement function. For functions with multiple modes (e.g., AC/DC voltage, resistance/continuity/diode), press the VÆLGE button to toggle between modes.
4.3 Målefunktioner
- Voltage (Ṽ / V―): Turn the dial to V. Use SELECT to switch between AC (̃) and DC (―). Connect leads in parallel to the circuit.
- Current (à / A―, mà / mA―, µÃ / µA―): Turn the dial to A, mA, or µA. Use SELECT to switch between AC (̃) and DC (―). Connect leads in series with the circuit. Ensure correct input jacks are used (10A MAX FUSED or 400mA MAX FUSED).
- Modstand (Ω): Turn the dial to Ω. Disconnect power from the circuit. Connect leads across the component.
- Continuity (→⊤): Turn the dial to Ω. Press SELECT until the continuity symbol appears. Disconnect power. Connect leads across the circuit. An audible tone indicates continuity.
- Diode Test (→⊤): Turn the dial to Ω. Press SELECT until the diode symbol appears. Disconnect power. Connect leads across the diode.
- Capacitance (‖): Turn the dial to ‖. Disconnect power and discharge the capacitor. Connect leads across the capacitor.
- Frekvens (Hz) / Duty Cycle (%): Turn the dial to Hz Duty. Use SELECT to switch between Frequency and Duty Cycle. Connect leads to the signal source.
- Temperature (°F / °C): Turn the dial to Temp. Use SELECT to switch between Fahrenheit and Celsius. Insert the thermocouple into the input jacks.
4.4 Specialfunktioner
- RELΔ (Relative Mode): Press to store the current reading as a reference. Subsequent readings will display the difference from this reference.
- RÆKKEVIDDE: Tryk for at skifte mellem automatisk og manuel områdeindstilling. I manuel tilstand skal du trykke gentagne gange for at skifte mellem områderne.
- MAX / MIN: Press to capture the maximum or minimum reading during a measurement session. Press again to cycle between MAX, MIN, and normal mode.
- AUTOHOLD: Press to hold the current stable reading on the display. Press again to release.
- Backlight (☀): Press the backlight button (often combined with AUTOHOLD) to illuminate the display for better visibility in low-light conditions.
5. Vedligeholdelse
5.1 Rengøring
Wipe the meter with a dry, lint-free cloth. Do not use abrasive cleaners or solvents. Ensure the meter is off and leads are disconnected before cleaning.
5.2 Udskiftning af batteri
Refer to Section 3.1 for battery replacement instructions. Replace batteries promptly when the low battery indicator appears to maintain measurement accuracy.
5.3 Udskiftning af sikringer
The MM1300 is equipped with internal fuses to protect against overcurrent in current measurement modes. If the meter fails to read current, the fuse may be blown. Fuse replacement should only be performed by qualified personnel.
- 10A MAX SIKRET: For the 10A current range.
- 400mA MAX SIKRET: For the mA/µA current ranges.
Always replace with fuses of the exact specified type and rating.
5.4 Opbevaring
When not in use for extended periods, remove the batteries to prevent leakage. Store the meter and its accessories in a cool, dry environment, away from direct sunlight and extreme temperatures.
6. Fejlfinding
If the meter does not function correctly, review følgende almindelige problemer:
- Display shows "LE.AD": This typically indicates that the test leads are connected to the current input jacks (A, mA/µA) but the rotary dial is set to a non-current function (e.g., Voltage, Resistance). Correct the lead connection or rotary dial setting.
- Display shows "0.000" or no reading:
- Ensure the meter is powered on and batteries are not low.
- Verify test leads are properly inserted and making good contact.
- Check if the correct function and range are selected for the measurement.
- In current modes, a blown fuse will result in no reading. Refer to Section 5.3 for fuse replacement.
- For modstand/kontinuitet skal du sørge for, at kredsløbet er spændingsløst.
- Inconsistent or erratic readings:
- Check for loose test lead connections at both the meter and the circuit.
- Sørg for, at batterierne ikke er ved at være flade.
- Verify the measurement environment is stable and free from strong electromagnetic interference.
- Måleren tænder ikke: Kontroller batteriinstallationen, og sørg for, at batterierne er friske.
If issues persist after troubleshooting, contact Klein Tools customer support or a qualified service technician.
