Free test & scanner questions
Everything about the trial version, supported scanners, and how activation works.
Non. DiagZone ne nécessite aucun fichier de démarrage ni de flashage. Si votre scanner est pris en charge et en état de fonctionnement, vous pouvez demander un essai et tester immédiatement.
Utilisez le numéro de série numérique indiqué dans l’application ou sur l’appareil (chiffres uniquement, sans espaces). Si votre numéro de série contient des lettres, il se peut qu’il ne soit pas pris en charge.
You’ll receive access for basic connectivity to verify that your scanner and app work with DiagZone before purchasing brand packages.
La version d’essai est limitée dans le temps. Après avoir reçu les identifiants de connexion, téléchargez les fichiers nécessaires et testez les fonctionnalités le jour même.
Une seule version d’essai par appareil/compte est autorisée. Si vous avez déjà bénéficié d’un essai (même ailleurs), une nouvelle demande peut être refusée.
