6.2. Menghubungkan Kabel Uji

Connect the test leads to the appropriate input jacks:

• Masukkan kabel tes hitam ke dalam DAPAT (Jack) umum.
• Untuk sebagian besar pengukuran (Volume)tage, Resistance, Diode, Continuity, mA Current), insert the red test lead into the VΩmA mendongkrak.
• Untuk pengukuran arus tinggi (hingga 10A), masukkan kabel uji merah ke dalam 10A mendongkrak.

7. Petunjuk Pengoperasian

Before making any measurement, ensure the test leads are correctly connected and the function switch is set to the desired range.

7.1. Volt AC/DCtage Pengukuran

1. Set the function switch to the desired ACV (~) or DCV (---) range (e.g., 200V, 600V).
2. Hubungkan kabel uji merah ke jack VΩmA dan kabel uji hitam ke jack COM.
3. Sentuhkan probe penguji ke titik-titik sirkuit di mana tegangantage harus diukur.
4. Baca vol.tagnilai e pada LCD.

7.2. Pengukuran Arus AC/DC

Peringatan: Never attempt to measure current on a circuit with voltage present across the current terminals. This can blow the fuse or damage the meter.

1. Matikan daya ke sirkuit.
2. Set the function switch to the desired ACA (~) or DCA (---) range (e.g., 200mA, 10A).
3. Connect the red test lead to the appropriate current jack (VΩmA for mA, 10A for 10A) and the black test lead to the COM jack.
4. Buka rangkaian tempat arus akan diukur dan hubungkan meter secara seri.
5. Berikan daya ke rangkaian dan baca nilai arus pada LCD.

7.3. Pengukuran Resistansi

1. Pastikan sirkuit atau komponen tersebut telah dimatikan alirannya.
2. Set the function switch to the desired Resistance (Ω) range (e.g., 200Ω, 20kΩ).
3. Hubungkan kabel uji merah ke jack VΩmA dan kabel uji hitam ke jack COM.
4. Sentuhkan probe penguji ke komponen atau rangkaian yang akan diukur.
5. Bacalah nilai resistansi pada LCD.
