2. Consignes de sécurité
To prevent electric shock or personal injury, and to avoid damage to the meter or the equipment under test, observe the following safety guidelines:
- Respectez toujours les codes de sécurité locaux et nationaux.
- Le Amprobe AM-570 is rated for CAT IV 600 V and CAT III 1000 V. Do not exceed these ratings.
- Avant utilisation, inspectez les cordons de test afin de détecter toute isolation endommagée ou tout métal exposé. Remplacez immédiatement les cordons endommagés.
- Vérifiez que le commutateur de fonction est dans la position correcte pour la mesure effectuée.
- Ne pas appliquer plus que le volume nominal.tage between terminals or between any terminal and ground.
- Soyez prudent lorsque vous travaillez avec des volumestages above 30 V AC RMS, 42 V peak, or 60 V DC. These voltagils présentent un risque d'électrocution.
- Coupez l'alimentation du circuit et déchargez tous les condensateurs haute tension.tage capacitors before performing resistance, continuity, diode, or capacitance tests.
- Do not operate the meter if it appears damaged or if it is not operating properly.
- Remplacez la pile dès que le témoin de pile faible apparaît afin de garantir des mesures précises.
- Lors de l'entretien du compteur, n'utilisez que les pièces de rechange spécifiées.

5. Installation
5.1 Installation de la batterie
- Assurez-vous que le compteur est éteint.
- Repérez le compartiment à piles à l'arrière de l'appareil.
- Utilisez un tournevis pour desserrer la vis qui fixe le couvercle de la batterie.
- Retirez le couvercle de la batterie.
- Insérez une nouvelle pile 9V en respectant la polarité.
- Replacez le couvercle de la batterie et fixez-le avec la vis.
5.2 Connexion des cordons de test
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: Pour voltage, resistance, frequency, capacitance, and diode/continuity measurements.
- mAµA: Pour milliampet microampmesures actuelles.
- 10A: For high current (up to 10A) measurements.

6. Mode d'emploi
The AM-570 features a rotary dial for selecting primary measurement functions and push buttons for secondary functions and settings.
6.1 Sélection de la fonction
Turn the rotary dial to the desired measurement function. Use the SÉLECTIONNER button to toggle between primary and secondary functions within a single dial position (e.g., AC/DC voltage, résistance/continuité/diode).
6.2 Fonctions de mesure
- 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.
- Résistance (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 SÉLECTIONNER until the continuity symbol appears. A continuous beep indicates continuity.
- Diode Test (→|): Select the Ω position and press SÉLECTIONNER until the diode symbol appears. Connect leads across the diode.
- Capacité (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 SÉLECTIONNER to toggle between frequency and duty cycle.
- Température (° C / ° F): Select the TEMP °C/°F position. Insert K-type thermocouple probes into the T1 and T2 inputs. Press SÉLECTIONNER to toggle between Celsius and Fahrenheit.
- Vol sans contacttage (PCI): Select the NCV position. Hold the top of the meter near a live conductor. The NCV indicator and audible alarm will activate if voltage est détecté.
- Low Z Mode: Select the LoZ V~ position for AC voltage measurements with low impedance. This helps to eliminate ghost voltaget.
- Filtre passe-bas: Activated automatically in certain AC voltage modes, this filter allows for accurate measurements on variable frequency drives.
6.3 Fonctions spéciales
- GAMME: 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.
- PRISE: Fige l'affichage actuel.
- PEAK (1ms): Captures fast transient peaks (positive and negative) with a 1ms response time.
