External Triggering - Agilent Technologies L34410A User Manual

Temperature is measured using the 2–wire or 4–wire resistance function. The above tables
N O TE
for resistance apply to temperature, but all temperature measurements use autoranging.
The range in use cannot be predicted; thus, nor can the delay. Use the TRIGger:DELay?
command to query the actual trigger delay for a temperature measurement.
For capacitance measurements the automatic trigger delay is zero (capacitor discharge is
part of the measurement). The continuity and diode test functions ignore the trigger delay.

External Triggering

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