Today I had the chance to play with Fluke 89IV and with one Fluke 87 first gen (made at 1994).
The digits on the 89IV LCD are too small for my taste, but hey this in not a review,
even so I tested the continuity mode, and the buzzer sound was terrible.
It was not a stray beep tone, but an repeatable beep-song with scalable volume.
Like a sound of an cheap alarm clock.
The old 87 first gen, was had the classic Fluke class about the beep sound and speed, but it is lots lower in volume from the latest 87V. (87-5)
