To start the test, press STEP on the switching mainframe to take it out of idle and start the
scan. The switching mainframes output pulse triggers Model 6485 to take a reading and
store it. Model 6485 then sends an output trigger pulse to the switching mainframe to
close the next channel. This process continues until all 10 channels are scanned, measured,
and stored.
