5. Pengaturan

5.1. Pemasangan Baterai

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

1. Pastikan multimeter dalam keadaan MATI.
2. Cari penutup kompartemen baterai di bagian belakang multimeter.
3. Gunakan obeng untuk melonggarkan sekrup yang mengencangkan penutup.
4. Remove the cover and insert a new 9V battery, observing correct polarity.
5. Pasang kembali penutupnya dan kencangkan sekrupnya.

5.2. Menghubungkan Kabel Uji

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

• VΩHz: Untuk volumetage, resistance, continuity, diode, and frequency measurements.
• ibu: Untuk pengukuran arus hingga 400mA.
• 10A: Untuk pengukuran arus hingga 10A.

6. Petunjuk Pengoperasian

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

6.1. Mengukur Tegangan AC/DCtage

1. Turn the rotary dial to V~ (AC Voltage) or V (DC Voltagdan).
2. Hubungkan kabel uji hitam ke jack COM dan kabel uji merah ke jack VΩHz.
3. Sentuhkan probe penguji ke titik-titik sirkuit di mana tegangantage harus diukur.
4. Baca vol.tagnilai e pada layar.

6.2. Mengukur Hambatan (Ohm)

1. Pastikan rangkaian dimatikan sebelum mengukur resistansi.
2. Turn the rotary dial to Ω.
3. Hubungkan kabel uji hitam ke jack COM dan kabel uji merah ke jack VΩHz.
4. Touch the test probes across the component or circuit segment.
5. Baca nilai resistansi di layar.

6.3. Measuring Current (Ampere)

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

1. Matikan sirkuit.
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. Hubungkan test lead hitam ke jack COM.
4. Putuskan rangkaian dan hubungkan probe uji secara seri dengan beban.
5. Nyalakan kembali rangkaian dan baca nilai arusnya.
6. De-energize the circuit before disconnecting the multimeter.

6.4. Using HOLD, MINMAX, and RANGE Functions

• MEMEGANG: Tekan tombol TAHAN untuk membekukan pembacaan saat ini pada layar. Tekan lagi untuk melepaskan.
• 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.
• JARAK: 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.
