B&K 1850 Frequency Counter Manual needed

[Mars777]

Hi there to all;

I recently acquired a B&K 1850 Frequency Counter & I need a user's manual for it. I cannot find one anywhere!

Does anyone out there know where I can acquire one? If not, does anyone have the same model & could please tell me detailed operations of this counter?

I have used all types of equipment out there, i.e. Oscilloscopes, Signal Generators, VTVM's, etc., but NOT a freq counter.

Thanks to all for listening,

Tom M.
