Help! Testing APC Knock Sensor, Ignition Input

I have a 1987 SPG (really, the wife thinks it's hers), trying to diagose basic-boost-only until approx 4,200 rpm. Anyone know:
1. What is the DC voltage produced by the knock sensor? Can't read at 0.4V detection limit of multimeter (tried on new sensor). Bentley and Townsend say only "a small voltage." May have to buy a better meter, need to know how low to go (e.g., how much to spend).
2. How to test ignition rpm input at APC?
Solonoid/pressure transducer/APC ground and power/vac hoses all test OK.
Thx in advance for your thoughts.
