50 HP E1312A/E1412A Multimeter Application Information Chapter 2
Default Delays If you do not specify a trigger delay, the multimeter automatically
determines a delay time (default delay) based on the present measurement
function, range, resolution, integration time and AC filter bandwidth setting.
The delay time is actually the settling time required before measurements to
ensure measurement accuracy. The default delay time is automatically
updated whenever you change the function or range. Once you specify a
delay time value, however, the value does not change until you specify
another value, reset the multimeter or do a
CONF or MEAS command. The
table below shows the default trigger delay times for all functions. This
delay will occur before each measurement (see the trigger system diagram
in Figure 2-1 on page 45).
NOTE: You can specify a shorter delay time than the default values shown.
However, the shorter settling time may not produce accurate measurements.
