2. Achtergrondverlichtingsknop: Hiermee kunt u de achtergrondverlichting van het scherm in- of uitschakelen.
3. Pauzeknop: Bevriest de huidige weergave.
4. MINMAX Button: Records the minimum, maximum, and average readings over time.
5. RANGE-knop: Schakelt tussen de automatische en handmatige afstandsmetingsmodus.
6. Rotary Function Dial: Selects the desired measurement function (e.g., V AC, V DC, Ohms, AmpS).
7. Ingangsaansluitingen:
   • VΩHz: Positieve input voor voltage, weerstand- en frequentiemetingen.
   • mA: Invoer voor milliamphuidige metingen (gesmolten).
   • 10A: Input for high current measurements up to 10 Amperes (fused).
   • COM: Gemeenschappelijke (negatieve) ingang voor alle metingen.

5. Instellen

5.1. Batterij installatie

The Fluke 77-4 is powered by a 9V battery. To install or replace the battery:

1. Zorg ervoor dat de multimeter is uitgeschakeld.
2. Locate the battery compartment cover on the rear of the multimeter.
3. Draai de schroef/schroeven los waarmee de kap vastzit.
4. Remove the cover and insert a new 9V battery, observing correct polarity.
5. Replace the cover and tighten the screw(s).

5.2. Testkabels aansluiten

Always connect the black test lead to the COM jack. Connect the red test lead to the appropriate input jack for your measurement:

• VΩHz: voor voltage, resistance, continuity, diode, and frequency measurements.
• mA: For current measurements up to 400mA.
• 10A: Voor stroommetingen tot 10A.

6. Gebruiksaanwijzing

Before taking any measurement, ensure the test leads are correctly connected and the function dial is set to the appropriate position.

6.1. AC/DC-spanning metentage

1. Turn the rotary dial to V~ (AC Voltage) or V (DC Voltagen).
2. Connect the black test lead to the COM jack and the red test lead to the VΩHz jack.
3. Touch the test probes to the circuit points where voltage moet worden gemeten.
4. Lees het deeltage-waarde op het display.

6.2. Measuring Resistance (Ohms)

1. Zorg ervoor dat het circuit spanningsloos is voordat u de weerstand meet.
2. Turn the rotary dial to Ω.
3. Connect the black test lead to the COM jack and the red test lead to the VΩHz jack.
4. Touch the test probes across the component or circuit segment.
5. Lees de weerstandswaarde af op het display.

6.3. Measuring Current (Amperes)

Voorzichtigheid: Current measurements require breaking the circuit and inserting the multimeter in series. Incorrect connection can blow the fuse or damage the meter.

1. Maak het circuit spanningsloos.
2. Determine the expected current range. For currents up to 400mA, turn the dial to mA and connect the red lead to the mA jack. For currents up to 10A, turn the dial to A and connect the red lead to the 10A jack.
3. Sluit het zwarte testsnoer aan op de COM-aansluiting.
4. Break the circuit and connect the test probes in series with the load.
5. Re-energize the circuit and read the current value.
6. De-energize the circuit before disconnecting the multimeter.

6.4. Using HOLD, MINMAX, and RANGE Functions

• HOUDEN: Druk op de HOLD-knop om de huidige waarde op het display te bevriezen. Druk nogmaals om de knop los te laten.
• MINMAX: Press the MINMAX button to activate recording. The meter will display the maximum, minimum, and average readings sequentially. Press again to cycle through Min, Max, Avg. Hold the button to exit.
• BEREIK: In auto-ranging modes, the meter automatically selects the best range. Press RANGE to switch to manual ranging. Each subsequent press will cycle through available ranges. Hold the button to return to auto-ranging.
