Automatic Trigger Delays

If TRIGger:DELay:AUTO is on, the instrument selects the trigger delay for you, as shown in the tables below.

All frequency and period measurements have an automatic trigger delay of 1 second.

The continuity and diode functions ignore the trigger delay.

The 2-wire and 4-wire temperature measurements use the corresponding 2-wire and 4-wire resistance measurement delays.
