Penyambungan kabel uji yang tepat sangat penting untuk pengukuran yang akurat dan aman.

1. Masukkan kabel uji berwarna hitam ke dalam jack input 'COM' (umum).
2. Untuk sebagian besar pengukuran (vol)tage, resistance, diode, continuity, and current up to 200mA), insert the red test lead into the 'VΩmA' input jack.
3. For high current measurements (up to 10A), insert the red test lead into the '10A' input jack. Always ensure the red lead is in the correct jack for the measurement type.

5. Petunjuk Pengoperasian

To begin, turn the rotary switch from 'OFF' to the desired measurement function and range.

5.1 Mengukur Tegangan DCtage (V=)

2. Atur sakelar putar ke tegangan DC yang diinginkan.tage (V=) rentang (misalnya, 200mV, 2V, 20V, 200V, 300V). Jika tegangantagJika nilai e tidak diketahui, mulailah dengan rentang tertinggi dan kurangi seperlunya.
3. Hubungkan probe uji melintasi komponen atau rangkaian yang akan diukur, perhatikan polaritasnya.
4. Baca vol.tagnilai e pada layar LCD.

5.2 Mengukur Vol ACtage (V ~)

1. Hubungkan kabel uji merah ke jack 'VΩmA' dan kabel uji hitam ke jack 'COM'.
2. Atur sakelar putar ke tegangan AC yang diinginkan.tagrentang e (V~) (misalnya, 200V, 300V).
3. Hubungkan probe penguji ke tegangan AC.tagsumber.
4. Baca vol.tagnilai e pada layar LCD.

5.3 Mengukur Arus DC (A=)

Peringatan: Jangan pernah menghubungkan multimeter secara paralel dengan tegangan.tage source when measuring current, as this can blow the fuse or damage the meter.

1. For current up to 200mA: Connect the red test lead to the 'VΩmA' jack.
2. For current up to 10A: Connect the red test lead to the '10A' jack.
3. Connect the black test lead to the 'COM' jack.
4. Set the rotary switch to the desired DC Current (A=) range (e.g., 200µA, 2mA, 20mA, 200mA, 10A).
5. Open the circuit where current is to be measured and connect the multimeter in series with the load.
6. Baca nilai saat ini pada layar LCD.

5.4 Mengukur Resistansi (Ω)

Peringatan: Pastikan rangkaian telah dimatikan dan semua kapasitor telah dikosongkan muatannya sebelum mengukur resistansi.

1. Hubungkan kabel uji merah ke jack 'VΩmA' dan kabel uji hitam ke jack 'COM'.
2. Set the rotary switch to the desired Resistance (Ω) range (e.g., 200Ω, 2kΩ, 20kΩ, 200kΩ, 2MΩ).
