I have been wondering about this for along time. The beeper loudness in mine is very low, in a quiet lab, and I have average hearing.
I find it hard to believe it was designed this low because you probably could not hear it in a somewhat noisy lab.
Have you looked inside? I'm curious if the cover sticker has been removed form the beeper.
I have searched for answers to this problem, but have found nothing. Does everyone think this is a acceptable?
Let me know what you find out.
