6. Arahan Operasi
The AM-570 features a rotary dial for selecting primary measurement functions and push buttons for secondary functions and settings.
6.1 Pemilihan Fungsi
Turn the rotary dial to the desired measurement function. Use the PILIH button to toggle between primary and secondary functions within a single dial position (e.g., AC/DC voltage, resistance/continuity/diode).
6.2 Fungsi Pengukuran
- 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.
- Rintangan (Ω): Select the Ω position. Ensure power is off and capacitors are discharged. Connect test leads across the component.
- Kesinambungan ())): Select the Ω position and press PILIH until the continuity symbol appears. A continuous beep indicates continuity.
- Diode Test (→|): Select the Ω position and press PILIH until the diode symbol appears. Connect leads across the diode.
- Kapasitansi (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 PILIH to toggle between frequency and duty cycle.
- Suhu (° C / ° F): Select the TEMP °C/°F position. Insert K-type thermocouple probes into the T1 and T2 inputs. Press PILIH to toggle between Celsius and Fahrenheit.
- Vol. Bukan Kenalantage (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 dikesan.
- Low Z Mode: Select the LoZ V~ position for AC voltage measurements with low impedance. This helps to eliminate ghost voltages.
- Penapis Lulus Rendah: Activated automatically in certain AC voltage modes, this filter allows for accurate measurements on variable frequency drives.
6.3 Fungsi Khas
- JULAT: Manually select the measurement range instead of auto-ranging.
- REL (Relative Mode): Measures the difference between a stored reference value and the current reading.
- MAX/MIN: Records the maximum and minimum values over a measurement period.
- TAHAN: Freezes the current display reading.
- PEAK (1ms): Captures fast transient peaks (positive and negative) with a 1ms response time.
