Its a pleasure the one bit that is good on this forum is people have patience and enjoy helping.

As I have never used a meter to test frequency before I am going to guess you set it to Hz and then put the black lead on Pin 8 (rest it on the base of the pin so it is firm) and then touch the pin with the red probe to measure 7 for 1,000,000 Hz (1Mhz) and pin 3 for 8Mhz - Be very careful not to slip to short leads - that will likely be fatal to one or more of the chips.
