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:

Figure 2-5 Trigger in 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.
