Function and
Aperture Change
Times
Table C-5 lists the times required for the multimeter to change its function
and aperture time. The times pertain to both SCPI and register-based
programming.

** Changing the function to ACV automatically sets a 250 ms
trigger delay. This delay can be changed with the Trigger
Delay command.
Note - range changes are approximately 200 µs.
Reading the Table For example, it takes the multimeter 12 ms to change its function from
ACV to DCV. It takes 23 ms to set the 10 us aperture time for DCV. Thus,
to change from ACV/16.7 ms aperture time to DCV/10 µs aperture time
would require:
12 ms (function change) + 23 ms (aperture time change) = 35 ms.
