Hi
It might be some kind of bearing failure detection
devise. The switches would be to select the frequency
to listen at. In a large shop, with a lot of machines
running ( like a printing press ), one needs something
check each bearing to see if it about to fail. When
a bearing is just starting to go bad, it growls.
The frequencies mentioned are in the range one would
expect for larger bearings.

No the LED is in the chassis. I started thinking it might be some sort of
heart
device timer as the deceased former owner of the
auctioned items was quite
elderly. I guess you could use it as a timer strobe.

Likely way off topic, but I acquired some sort
of frequency device in
an auction junk box. It's a well machined device made by MECOS, made
in W.Germant. It's about 2" square by 1/2" powered by a Li. battery
and has micro-switches labelled 3 hz, 7.8 hz, 14.0 hz and a small led
that flashes at the selected frequency. Anyone have any idea what it
might be ?
A search turned up that MECOS makes Active Magnetic Bearings and
control boards and programs.
Could this be some sort of timing device used for calibrating the speed of
something? Is the led separate from the chassis?

That sounds plausable since MECOS makes Active Magnetic Bearings.
I drove taxi part-time some 20 years ago and listened in fascination to a
software engineer who had developed a program to use frequencies to check
for metal stress on large process machines thereby eliminating regular
inspections with expensive shutdowns . His manufacturer host had just flown
him in to Toronto from the US and they were discussing the process.
