Maklumat Keselamatan

Sentiasa patuhi langkah berjaga-jaga keselamatan semasa menggunakan sebarang peralatan ujian elektrik. Kegagalan berbuat demikian boleh mengakibatkan kecederaan atau kerosakan pada meter atau peralatan yang diuji.

• jangan apply more than the rated voltage, as specified in the specifications section, between terminals or between any terminal and earth ground.
• jangan use the meter if it is damaged or operating abnormally. Inspect the case and test leads before use.
• jangan use the meter around explosive gas, vapor, or in damp atau persekitaran basah.
• Always use the correct terminals, function, and range for your measurements.
• Berhati-hati semasa bekerja dengan voltagadalah melebihi 30V AC RMS, puncak 42V atau 60V DC. Ini voltagia menimbulkan bahaya kejutan.
• Putuskan sambungan kuasa litar dan nyahcas semua voltan tinggitage kapasitor sebelum menguji rintangan, kesinambungan, diod atau kemuatan.
• Ensure the test leads are fully seated in the meter's input jacks.
• Gantikan bateri dengan segera apabila penunjuk bateri lemah muncul untuk memastikan bacaan yang tepat.

Pemasangan Bateri

The Fluke 107 comes with two AAA batteries pre-installed. If replacement is needed:

1. Pastikan multimeter dimatikan.
2. Cari petak bateri di belakang meter.
3. Open the battery compartment cover by twisting the lock and sliding it open.
4. Remove the old batteries and insert two new AAA batteries, observing the correct polarity (+/-).
5. Tutup penutup petak bateri dengan selamat.

Menghubungkan petunjuk ujian

The Fluke 107 has three recessed banana jacks:

• A: For current measurements (up to 10A).
• COM: Common terminal for all measurements (black test lead).
• VΩHz: For voltage, resistance, capacitance, frequency, and diode tests (red test lead).

Always connect the black test lead to the COM jack. Connect the red test lead to the appropriate jack based on the measurement you intend to perform.

Using the Smart Strap Magnetic Lanyard

The included Smart Strap allows for hands-free operation by attaching the meter to a ferrous metal surface or by configuring it as a stand. The strap has a slot that fits into the meter's case and secures with Velcro. The magnetic end can then be used to attach the meter to metal surfaces or to itself to form a viewberdiri.

Arahan Operasi

Kawal Selesaiview

The Fluke 107 features a central rotary selector knob and three soft-touch buttons:

• Tombol Pemilih Putar: Used to select the desired measurement function (OFF, AC Volts, DC Volts, AC mV, Ohms/Continuity/Diode, Capacitance, AC/DC Amps).
• Butang HOLD: Freezes the current reading on the display. Press again to resume live readings.
• Hz % Button: Toggles between frequency (Hz) and duty cycle (%) display when measuring AC Volts or AC Amps.
• Yellow Function Button:
  • In AC/DC Amps mode: Toggles between AC and DC current measurement.
  • In Ohms mode: Toggles between resistance, continuity test, and diode test.
• Butang Lampu Latar: Activates or deactivates the display backlight. The backlight automatically turns off after 2 minutes of inactivity, but this can be overridden.

Fungsi Pengukuran

The meter is auto-ranging by default for most functions, simplifying operation.

1. Voltage Pengukuran (AC/DC):
   • Pusingkan tombol putar ke V~ untuk AC voltage atau V- untuk DC voltage.
   • Connect the red test lead to the VΩHz jack and the black test lead to the COM jack.
   • Apply the test probes across the circuit or component to measure voltage.
2. Pengukuran Semasa (AC/DC):
   • Pusingkan tombol putar ke A~ (AC) or A- (DC). Use the yellow button to toggle between AC and DC if needed.
   • Connect the red test lead to the A (10A FUSED) jack and the black test lead to the COM jack.
   • penting: Connect the meter in series with the circuit to measure current. Ensure the circuit is de-energized before connecting the meter.
3. Pengukuran Rintangan (Ω):
   • Pusingkan tombol putar ke Ω.
   • Connect the red test lead to the VΩHz jack and the black test lead to the COM jack.
   • Apply the test probes across the component. Ensure the circuit is de-energized.
4. Ujian Kesinambungan:
   • Pusingkan tombol putar ke Ω. Press the yellow button until the continuity icon (speaker symbol) appears.
   • Connect the red test lead to the VΩHz jack and the black test lead to the COM jack.
   • A continuous beep indicates a complete circuit (resistance less than 70Ω). "OL" indicates an open circuit.
5. Ujian Diod:
   • Pusingkan tombol putar ke Ω. Press the yellow button until the diode icon (arrow with line) appears.
   • Connect the red test lead to the VΩHz jack and the black test lead to the COM jack.
   • Place the red probe on the anode and black probe on the cathode of the diode. The display shows the forward voltage drop. Reverse the probes; "OL" should be displayed for a good diode.
6. Pengukuran Kapasitans:
   • Turn the rotary knob to the capacitance symbol (-||-).
   • Connect the red test lead to the VΩHz jack and the black test lead to the COM jack.
   • penting: Discharge capacitors before connecting them to the meter. Apply probes across the capacitor. Readings may take up to 18 seconds to stabilize.
7. Frequency (Hz) and Duty Cycle (%) Measurement:
   • Select AC Volts or AC Ampfungsi s.
   • Tekan ke % Hz button to display frequency. Press again for duty cycle. Press a third time to return to voltage/current display.

Matikan Auto

The meter automatically powers off after 20 minutes of inactivity to conserve battery life. This feature can be disabled if continuous operation is required.

Penyelenggaraan

Pembersihan

Lap kes dengan iklanamp cloth and mild detergent. Do not use abrasives or solvents. Keep the display clean and free from scratches.

Penggantian Bateri

Refer to the "Battery Installation" section under Setup for detailed instructions. Replace batteries when the low battery indicator appears on the display.

Fuse Check and Replacement

The Fluke 107 has a single internal fuse for the Amps function. To check the fuse:

1. Putar suis pemilih ke Ω kedudukan.
2. Plug the red test lead into the VΩHz jack.
3. Insert the probe tip of the red test lead into the A (10A FUSED) jack until electrical contact is made.
4. A reading of less than 0.5Ω indicates a good fuse. An "OL" reading indicates a blown fuse that requires replacement.

Fuse replacement requires opening the meter case by removing three screws. It is recommended that fuse replacement be performed by qualified personnel or a Fluke service center.
