Triggering the Multimeter
The 34410A/11A/L4411A triggering system allows you to generate triggers 
either manually or automatically, take multiple readings per trigger, and insert 
a delay before each reading. The 34411A/L4411A also allows you to set a level 
for internal triggering, and to set up pre-triggering.
Selecting a Trigger Source
Specify the source from which the multimeter will accept a trigger. The 
power–on default is auto triggering from the front panel. Several types of 
triggering are described in the sections that follow.
• Front Panel Operation: 
• Press   once to go to the single trigger mode. A single reading is 
taken, and another reading is taken each time you press  , or when a 
hardware trigger is received on the Ext Trig connector.
• Press  and select:
TRIGGER > AUTO To return to auto trigger mode.
TRIGGER > LEVEL To select internal (level) triggering (34411A only).
TRIGGER > HOLD To select reading hold mode.
TRIGGER > SETUP To enter the trigger setup menu.
• Remote Interface Operation: The following command selects the trigger source 
from the remote interface:
TRIGger:SOURce {IMMediate>EXTernal|BUS>INTernal}
Where INTernal triggering applies only to the 34411A/L4411A.
Refer to the Agilent 34410A/11A/L4411A Programmer’s Reference Help for 
a complete description and syntax for this command.
