Bien pour utilisation à main levée. Sortie analogique inutilisable.

Grosse déception avec ce Sonomètre. Les fonctionnalités de base sont au rendez-vous. La précision est correcte. Et il y a même quelques bonnes surprises avec une vis de calibration, et une vis de fixation pour montage sur trépied. Si vous voulez utiliser ce sonomètre en utilisation de base "à main levée", très bien. Mais alors, pourquoi cette mauvaise note? Parce que j'avais acheté ce sonomètre spécialement pour relier la sortie analogique à un oscilloscope afin de pouvoir tracer les variations de niveau sonore. Hélas, à la sortie "AC", le sonomètre fournit un signal totalement inutilisable. À titre d'exemple, j'ai joint à ce commentaire un graphique montrant ce que je lis lorsque je balance un signal avec une amplitude de 100dB SPL. Si quelqu'un peut interpréter ça, merci de me le dire. À moins tout simplement que mon exemplaire ne soit défectueux? Bref, je renvoie le produit dés que possible...
