Review: God value for the money just one point every time it's turned on its in dc mode and then one press of the function button will change it to ac
Review: Aucun soucis à signaler sur mon modèle 4000, tous les commentaires négatifs que j'ai lu n'impactent pas le miens, par exemple : - test 4A DC : mesure à 4A +/- 1% environ, le placement du câble dans la pince faisant varier légèrement la mesure, je n'ai pas encore testé la fonction A/AC vu que j'ai pris ce modèle en grande priorité pour sa capacité A/DC. - test 30.00V DC : mesure 30.00 V ; j'ai fait d'autres mesures à 20V, 4,2V et 1V avec la même précision. Je ne vais pas aller plus loin dans le détail, toutes les autres fonctions marchent de façon nominales, j'ai juste un doute sur des mesures de rapport cyclique qui ne sont pas conforme quand j'arrive près de 10 ou de 90 % mais j'utilise un petit module chinois très basique pour la génération et ça peut largement expliquer l'erreur. Le cordon fourni mesure 1 mètre, aucun souci pour l'insérer une fois les capuchons de protections retirés 😊 (sans mes lunettes, je me suis fait piéger !) Bref, pour moi, dans l'état actuel de mes test, c'est un très bon appareil.

## Features

- Versatile Digital Clamp Meter: Accurately measures AC/DC Current, AC/DC Voltage, Capacitance, Frequency, Duty Cycle, Resistance, Diode, Continuity and Live Wire Tests. This clamp meter is a really useful tool for solving industrial and household electrical issues.
- Non-contact Voltage Testing: This Clamp Meter features non-contact voltage testing with sound and light alarms. When the Meter senses a weak AC signal, the green indicator light will come on and the buzzer will emit a slow, audible beep. when the Meter senses a strong AC signal, the red indicator light will come on and the buzzer will emit a brief beep.
- Multifunctional & Easy to read: Support Data Hold, Max/Min, Auto power off after 15 minutes inactivity, low battery indicator and continuity buzzer. The LCD Backlit Screen and Flashlight make it easy to use in a dark working area. ZERO function decreases the data error influenced by the Earth’s magnetic field, and helps you to obtain a more accurate measurement.
- Large Jaw Opening: The jaw opening measures current in a conductor without touching or interrupting the circuit. Its slim and compact size makes it easy to operate in narrow spaces. This clamp meter has passed the environmental pollution test degree 2 and overvoltage category III 600V safety standards.
- Additional Tips: To measure the current you need to clamp the meter around one of the wires and not the whole power cord. Ensure the conductor to betested is in the center of the clamp head. The clamp Jaw is only used to measure current. Do not measure voltage by clamping the conductor being measured.

AstroAI Digital Clamp Meter Multimeter 4000 Great for the money, a litter bit more plastic feeling than I'll like. but this is packed full of features like back-lit display, LED light, AC/CD Reading with the clamp, Zero out the reading before taking measurement, Holding the measurement on the screen, non-contact voltage testing. Auto power off after.
