   • COM: Zajednički (negativni) ulaz za sva mjerenja.

5. Podešavanje

5.1. Instalacija baterije

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

1. Provjerite je li multimetar isključen.
2. Pronađite poklopac odjeljka za baterije na stražnjoj strani multimetra.
3. Koristite odvijač da biste otpustili vijak(e) koji pričvršćuju poklopac.
4. Remove the cover and insert a new 9V battery, observing correct polarity.
5. Vratite poklopac i zategnite vijke.

5.2. Povezivanje ispitnih vodova

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

• VΩHz: Za voltage, resistance, continuity, diode, and frequency measurements.
• mA: Za mjerenja struje do 400mA.
• 10A: Za mjerenja struje do 10A.

6. Uputstvo za upotrebu

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

6.1. Mjerenje AC/DC naponatage

1. Turn the rotary dial to V~ (AC Voltage) or V (DC Voltagi).
2. Spojite crni mjerni kabel na COM priključak, a crveni mjerni kabel na VΩHz priključak.
3. Dodirnite mjerne sonde tačkama strujnog kola gdje je voltage treba izmjeriti.
4. Pročitajte voltage vrijednost na ekranu.

6.2. Measuring Resistance (Ohms)

1. Prije mjerenja otpora provjerite je li strujno kolo bez napona.
2. Turn the rotary dial to Ω.
3. Spojite crni mjerni kabel na COM priključak, a crveni mjerni kabel na VΩHz priključak.
4. Touch the test probes across the component or circuit segment.
5. Očitajte vrijednost otpora na zaslonu.

6.3. Measuring Current (Amperes)

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

1. Isključite strujno kolo.
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. Povežite crni ispitni kabel na COM utičnicu.
4. Break the circuit and connect the test probes in series with the load.
5. Ponovo uključite strujni krug i očitajte trenutnu vrijednost.
6. De-energize the circuit before disconnecting the multimeter.

6.4. Using HOLD, MINMAX, and RANGE Functions

• DRŽI: Pritisnite dugme HOLD da biste zamrznuli trenutno očitanje na ekranu. Pritisnite ponovo da biste otpustili.
• 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.
• RANGE: 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.
