4. Setup
4.1 Installazzjoni tal-batterija
The GD166B requires 3 x 1.5V AAA batteries (not included) for operation.
- Sib il-kompartiment tal-batterija fuq wara tal-miter.
- Uża tornavit biex tiftaħ l-għatu tal-kompartiment tal-batterija.
- Insert three AAA batteries, ensuring correct polarity (+ and -).
- Ibdel l-għatu tal-kompartiment tal-batterija u waħħalha bil-kamin.
4.2 Konnessjoni tal-wajers tat-test
For measurements requiring test leads (e.g., voltage, resistance, continuity, diode, capacitance, temperature), connect them as follows:
- Daħħal il-wajer tat-test iswed fil-jack tad-dħul "COM" (komuni).
- Insert the red test lead into the "INPUT" (positive) input jack.

Figure 4.2.1: Test Lead Connection. This image illustrates the correct way to connect the test leads to the meter's input jacks for various measurements.
5. Istruzzjonijiet Operattivi
5.1 Power On/Off
Agħfas il- Buttuna tal-qawwa (⑂) to turn the meter on or off.
5.2 Għażla tal-Funzjoni
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 Kejl
- Connect the red test lead to the "INPUT" jack and the black test lead to the "COM" jack.
- Agħżel il-vol xieraqtage range (or use Smart Auto mode).
- Qabbad il-wajers tat-test b'mod parallel maċ-ċirkwit jew il-komponent li għandu jitkejjel.
- Aqra l-voltagIl-valur fuq il-wiri.
5.3.2 Kejl tal-Kurrent AC/DC (Clamp)
For current measurements, use the clamp jaw. Ensure the circuit is de-energized before clamping.
- Select the AC or DC current function.
- Iftaħ il-clamp jaw and enclose only one conductor of the circuit.
- Agħlaq il-clamp jaw completely.
