6. Istruzzjonijiet Operattivi
The AM-570 features a rotary dial for selecting primary measurement functions and push buttons for secondary functions and settings.
6.1 Għażla tal-Funzjoni
Turn the rotary dial to the desired measurement function. Use the AGĦŻEL button to toggle between primary and secondary functions within a single dial position (e.g., AC/DC voltage, reżistenza/kontinwità/dijodu).
6.2 Funzjonijiet tal-Kejl
- Voltage (V~ / V--): Select the V~ (AC) or V-- (DC) position. Connect test leads in parallel with the circuit.
- Current (10A / mAµA): Select the 10A or mAµA position. Connect the meter in series with the circuit. Ensure correct terminal connection.
- Reżistenza (Ω): Select the Ω position. Ensure power is off and capacitors are discharged. Connect test leads across the component.
- Continuity ())): Select the Ω position and press AGĦŻEL until the continuity symbol appears. A continuous beep indicates continuity.
- Diode Test (→|): Select the Ω position and press AGĦŻEL until the diode symbol appears. Connect leads across the diode.
- Kapaċità (F): Select the F position. Ensure power is off and capacitors are discharged. Connect leads across the capacitor.
- Frequency (Hz) / Duty Cycle (%): Select the Hz% position. Connect leads to the signal source. Press AGĦŻEL to toggle between frequency and duty cycle.
- Temperatura (° C / ° F): Select the TEMP °C/°F position. Insert K-type thermocouple probes into the T1 and T2 inputs. Press AGĦŻEL to toggle between Celsius and Fahrenheit.
- Mhux Kuntatt Voltage (NCV): Select the NCV position. Hold the top of the meter near a live conductor. The NCV indicator and audible alarm will activate if voltage jiġi skopert.
- Low Z Mode: Select the LoZ V~ position for AC voltage measurements with low impedance. This helps to eliminate ghost voltages.
- Filtru Low Pass: Activated automatically in certain AC voltage modes, this filter allows for accurate measurements on variable frequency drives.
6.3 Funzjonijiet Speċjali
- GANJA: Manually select the measurement range instead of auto-ranging.
- REL (Modalità Relattiva): Measures the difference between a stored reference value and the current reading.
- MAX/MIN: Records the maximum and minimum values over a measurement period.
- ŻOMM: Freezes the current display reading.
- PEAK (1ms): Captures fast transient peaks (positive and negative) with a 1ms response time.
