5. Parentah Operasi
5.1 Daya Hurung/Pareuman
Pencét éta Tombol daya (⑂) to turn the meter on or off.
5.2 Pamilihan Fungsi
The GD166B features a "Smart Measurement (Auto)" mode, which automatically identifies the measurement type (voltage, resistance, continuity) when test leads are connected. For other specific functions, use the FUNC button to cycle through modes or the rotary dial if present (though this model appears button-driven).
5.3 Common Measurements
5.3.1 AC/DC Voltage Pangukuran
- Connect the red test lead to the "INPUT" jack and the black test lead to the "COM" jack.
- Pilih vol anu cocogtage range (or use Smart Auto mode).
