Keithley 2010 User Manual

To run the test and store readings in the Model 2010 with the unit set for external triggers,
press STEP or SCAN. The Model 2010 waits (with the asterisk annunciator lit) for an external
trigger from the Model 7001/7002.
Press STEP on the Model 7001/7002 to take it out of idle and start the scan. The scanner's
output pulse triggers the Model 2010 to take a reading, store it, and send a trigger pulse. The
following explanation on operation is referenced to the operation model shown in Figure 3-8.
Pressing EXT TRIG then STEP or SCAN on the multimeter places it at point A in the
flowchart, where it is waiting for an external trigger.
Pressing STEP takes the Model 7001/7002 out of the idle state and places operation at
point B in the flowchart.
For the first pass through the model, the scanner does not wait at point B for a trigger.
Instead, it closes the first channel.
After the relay settles, the Model 7001/7002 outputs a Channel Ready pulse. Since the
instrument is programmed to scan ten channels, operation loops back up to point B,
where it waits for an input trigger.
