Picotest M3500A User Manual page 73

Front Panel Operation
Use the front panel buttons - AUTO TRIGGER for auto triggering and
SINGLE for single triggering.
External Hardware
You apply a trigger pulse to the Ext TRIG (BNC) terminal on the rear
panel. External hardware triggering is like using single trigger but the
trigger source is an external hardware. When the multimeter receives a
pulse from the trigger source, it takes one reading, or a specified number
of readings. To set the external hardware trigger, press both the SHIFT +
SINGLE buttons to enable external hardware trigger. The lit "EXT"
annunciator on the display indicates the enabling of the external
hardware trigger.
External Triger Terminal
You can trigger the M3500A by using a low-true pulse to the Ext Trig
(external trigger) terminal located on the rear panel. And to use this
terminal via the remote interface, you have to select the external trigger
source by using the TRIGer:SOURce EXTernal command.
