Hey! Good to hear from you my friend!

What if we don't have a TTL or CMOS choice on our probe? Tenma 72-500.

I was able to find your manual for the logic probe online. www.farnell.com/datasheets/1843672.pdf
It supports both TTL and CMOS using a percentage of the high and low voltages to determine the logic level.
