External Trigger
External triggering takes one reading (or the specified
number of readings in data logger) each time the multimeter
receives a pulse on the rear- panel external trigger connector.
The multimeter uses the rising edge (POS) of the external
trigger signal to trigger a reading. Diagram below shows the
external trigger connector:

The trigger annunciator turns on when the multimeter is
waiting for an external trigger.
The rear panel trigger out connector provides a pulse after
the completion of each measurement. Trigger out and
external trigger implement a standard hardware handshake
sequence between measurement and switching devices.
Trigger Out
The Trigger out signal cannot be configured and is
implemented in four ways:
In local mode, a trigger out signal is sent whenever a
measurement is updated on the front panel.
In remote mode, a trigger out signal is sent whenever a
measurement is taken by the user through using command.
