Automatic Trigger Delays
If you do not specify a trigger delay, the instrument selects a delay
for you. The delay is determined by the function, range, integration time,
and ac filter setting as shown below.
DC Voltage, Thermocouple, DC Current (for all ranges):
Resistance, RTD, Thermistor (2- and 4-wire):
AC Voltage, AC Current (for all ranges):
Frequency, Period:
Digital Input, Totalize:
