Triggering the Multimeter
At power-on, the default trigger source is auto-triggering. Auto-triggering takes
continuous readings at the fastest rate possible for the selected measurement
configuration. To make a trigger measurement, follow the steps below:
Immediate Triggering
The immediate triggering mode is available from the remote interface only.
In the immediate trigger mode, the trigger signal is always present. When you
place the multimeter in the wait-for-trigger state, the trigger is issued
immediately. This is the default trigger source for remote interface operation.
– Remote Interface Operation: The following command selects the immediate
Software (Bus) Triggering
The bus trigger mode is available from the remote interface only.
The bus trigger mode is initiated by sending a bus trigger command, after
selecting BUS as the trigger source.

2 Specify the multimeter's trigger source. Choices are as below:
– Software (bus) trigger from the remote interface.
– An immediate internal trigger (default trigger source).
– An external trigger from an external trigger pulse.
3 Ensure that the multimeter is ready to accept a trigger from the specified
source (called the wait-for-trigger state).
trigger source:
TRIGger:SOURce IMMediate
The CONFigure and MEASure? commands automatically set the trigger source
to IMMediate.
