External Triggering

External triggering takes one reading (or the specified number of readings)
each time the multimeter receives a pulse on the rear–panel (coaxial) Ext
Trig terminal. You may select whether the multimeter uses the rising edge
(POS) or falling edge (NEG) of the applied external trigger signal to trigger a
reading (see
