VM COMP (Voltmeter Complete) Terminal
The real panel VM COMP terminal provides a low-true pulse after
finishing each measurement. The VM COMP and external trigger shown
below provides a standard hardware handshake sequence between
measuremen and switching devices.
Remote Interface Operation (By software or internal trigger)
By software trigger:
The software trigger is similar to the single
triggering, but instead of using the “SINGLE” button on the front panel,
you send a command from your PC to the multimeter to generate an
event. For using software trigger, use the following command from
your PC terminal to set trigger source:
TRIGger:SOURce BUS
By internal trigger:
The internal trigger is the default trigger mode
for the Remote Interface Operation. In the internal trigger mode, a
trigger signal will be issued whenever the multimeter is in the wait-for-
trigger state. To set the internal trigger, use the following command
from your PC terminal:
TRIGger:SOURce IMMediate
