Subject: Automatic Switch / Circuit "Scanner"

Desperately seeking for solution to the following problem:

I have an ordinary multimeter. Presently I would need to probe the pairs of probes onto each individual resistor and record the value on the multimeter one by one. I would like to semi-automate the process as I need to measure a big batch of 76 resistors, fixed in a row. I have managed to acquire a fine probe that has 76 pairs of fingers that will contact the resistance and measure the resistance value. Right now I need a switching circuit that will switch each pair of probe, a pair at a time, so that the values are displayed on the multimeter. But I do not know how to start from there. Time-delay option might be needed.

Thanks in advance for all the help and time.

Desperate and wit-less noe
