- Assegureu-vos que l'interruptor de funció estigui en la posició correcta per a la mesura que s'està realitzant.
- No apliqueu més del volum nominaltage between terminals or between any terminal and ground.
- Tingueu precaució quan treballeu amb voltagper sobre de 30 V CA RMS, 42 V pic o 60 V CC. Aquests voltagsuposen un risc de xoc.
- Desconnecteu l'alimentació del circuit i descarregueu totes les emissions d'alt volumtage capacitors before performing resistance, continuity, diode, or capacitance tests.
- No feu funcionar el mesurador si sembla que està danyat o si no funciona correctament.
- Substituïu la bateria tan bon punt aparegui l'indicador de bateria baixa per garantir lectures precises.
- Quan feu servir el mesurador, utilitzeu només peces de recanvi especificades.

5. Configuració
5.1 Instal·lació de la bateria
- Assegureu-vos que el comptador estigui apagat.
- Localitzeu el compartiment de la bateria a la part posterior del mesurador.
- Feu servir un tornavís per afluixar el cargol que fixa la tapa de la bateria.
- Traieu la tapa de la bateria.
- Introduïu una pila nova de 9 V, respectant la polaritat correcta.
- Substituïu la tapa de la bateria i fixeu-la amb el cargol.
5.2 Connexió dels cables de prova
Always connect the black test lead to the COM (common) terminal. Connect the red test lead to the appropriate input terminal based on the measurement function:
- VΩHz: For voltage, resistance, frequency, capacitance, and diode/continuity measurements.
- mAµA: For milliampere i microampmesures actuals.
- 10A: For high current (up to 10A) measurements.

6. Instruccions de funcionament
The AM-570 features a rotary dial for selecting primary measurement functions and push buttons for secondary functions and settings.
6.1 Selecció de la funció
Turn the rotary dial to the desired measurement function. Use the SELECCIONA button to toggle between primary and secondary functions within a single dial position (e.g., AC/DC voltage, resistència/continuïtat/díode).
6.2 Funcions de mesura
- 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.
- Resistència (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 SELECCIONA until the continuity symbol appears. A continuous beep indicates continuity.
- Diode Test (→|): Select the Ω position and press SELECCIONA until the diode symbol appears. Connect leads across the diode.
- Capacitat (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 SELECCIONA 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 SELECCIONA to toggle between Celsius and Fahrenheit.
- Vol. Sense contactetage (NCV): Select the NCV position. Hold the top of the meter near a live conductor. The NCV indicator and audible alarm will activate if voltages detecta e.
- Low Z Mode: Select the LoZ V~ position for AC voltage measurements with low impedance. This helps to eliminate ghost voltages.
- Filtre de pas baix: Activated automatically in certain AC voltage modes, this filter allows for accurate measurements on variable frequency drives.
6.3 Funcions especials
- GAMMA: 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.
- MANTENIM: Freezes the current display reading.
- PEAK (1ms): Captures fast transient peaks (positive and negative) with a 1ms response time.
