5.1. Turning the Meter On/Off

Rotate the central rotary switch from the "OFF" position to any desired measurement function to turn the meter ON. To turn OFF, rotate the switch back to the "OFF" position.

5.2. Measuring AC/DC Current (Amps)

1. Rotate the rotary switch to the A~ (Penyaman Udara Amps) or A= (DC Amps) kedudukan.
2. Tekan clamp opening lever to open the jaws.
3. Encircle a single conductor with the clamp rahang. Pastikan rahang ditutup sepenuhnya.
4. Baca nilai semasa pada paparan.

5.3. Measuring AC/DC Voltage (Voltan)

1. Rotate the rotary switch to the V~ (AC Volts) or V= (DC Volts) position.
2. Connect the test leads to the appropriate input jacks on the meter.
3. Connect the test lead probes across the circuit or component to be measured.
4. Baca voltagnilai e pada paparan.

5.4. Measuring Resistance (Ohms)

1. Rotate the rotary switch to the Ω (Ohms) position.
2. Pastikan litar atau komponen dinyahtenagakan sebelum menyambungkan petunjuk ujian.
3. Connect the test lead probes across the component to be measured.
4. Baca nilai rintangan pada paparan.

5.5. Using In-rush Current Function

The in-rush function is used to measure the starting current of motors or other inductive loads.

1. Set the rotary switch to the AC Amps (A~) kedudukan.
2. Press the "In-rush" button (if available, or refer to specific button for this model).
3. Clamp the meter around the motor's power conductor.
4. Start the motor. The meter will capture and display the peak in-rush current.

5.6. Fungsi Tahan Paparan

Press the "HOLD" button to freeze the current reading on the display. Press it again to release and resume live readings.

6. Penyelenggaraan

6.1. Pembersihan

Lap bekas meter dengan iklanamp kain dan detergen lembut. Jangan gunakan bahan pelelas atau pelarut. Pastikan meter kering sebelum disimpan atau digunakan.

6.2. Penggantian Bateri

Refer to Section 4.1 for battery installation and replacement instructions. Replace batteries when the low battery indicator appears on the display to ensure accurate measurements.
