5. Bedryfsinstruksies
5.1. General Measurement
The ANENG GN703 features intelligent automatic recognition, allowing it to automatically identify and measure resistance, capacitance, inductance, and diodes. Ensure good contact between the test ends of the tweezers and the component being measured.
5.2. Specific Measurement Modes
The device supports various measurement modes. You can use the AUTO range or manually switch to specific modes for Resistance, Capacitance, Inductance, Diode, and Continuity (On-off beeping).
- Weerstand: Use the AUTO range or manually switch to the resistance range. Ensure the tweezers make reliable contact with the resistor being tested.
- Diode: Switch to the diode range. Ensure reliable contact between the tweezers and the diode. Conduction voltage minder as 0.7V.
- Kapasitansie: Use the AUTO range or manually switch to the capacitance range. Ensure reliable contact between the tweezers and the capacitor. Let wel: Discharge the capacitor before measurement to avoid damaging the instrument.
- Induktansie: Adjust to the inductance mode. Ensure reliable contact between the test ends on both sides of the tweezers and the measured inductance.
- On-off beeping (Continuity): When testing a diode with a beeper, a continuous beeping sound will be emitted when the measured value is less than 50Ω.
5.3. Test Frequencies and Levels
The GN703 supports three test frequencies (100Hz, 1KHz, 10KHz) and two test levels (0.3V, 0.6V) for comprehensive and precise test results.
5.4. Data hou
The device supports data hold functionality. Short press the 'HD/Set' button to hold the current data on the display.
