[time-nuts] Frequency Difference meter 100-7

[Alan Melia]

Seeing Stan's query about the Tracorreminded me I have what I think is a
slightly older unit made by Montronics. I have been totally unable to find
any information or manuals on this unit. It is presumably similar to the
Traco, Fluke and Keithley equipment of later years.

I would very much appreciate if someone could point me at ant
information/specs/manuals.

Thanks
