Voltmeter Complete Terminal
The rear-panel VM Comp (voltmeter complete) terminal provides a
low-true pulse after the completion of each measurement. Voltmeter
complete and external trigger (see below) implement a standard hardware
handshake sequence between measurement and switching devices.
External Trigger Terminal
You can trigger the multimeter by applying a low-true pulse to the
rear-panel Ext Trig (external trigger) terminal. To use this terminal
from the remote interface, you must select the external trigger source
(
TRIGger:SOURce EXTernal ).
You can use a simple switch to generate an external trigger using the
Ext Trig input as shown below.
