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 tests ignore the trigger delay.
The 2-wire and 4-wire temperature measurements use the corresponding 2-wire and 4-wire resistance
measurement delays.
