Heathkit Model IM-2410
Frequency Counter
Click for larger photo.
This is a useful piece to have around. My main use for it is to
periodically check the alignment of my signal generator. It has two
frequency ranges, 10 hz to 50 mhz, and 20 mhz to 225 mhz, and gate
settings of .1 sec and 1 sec. The digits are all displayed via
LEDs.
A manual is available on my Downloads
page, or by clicking here.
