Notes:
1. Conditions: Input is on range, HP-85 controller.
2. Preamp settling time (to 12%) is 2 seconds on preamp
ranges (2,20,20OpA), and must be taken into account by
the user.
A primary consideration is the length of time it takes to ob-
tain a reading once the instrument is triggered to make a con-
version. The length of time will vary somewhat depending on
the selected function and trigger mode. Table 3-15 gives
typical times
3. Volt time/error also apply to external feedback.
4. V/I time/error is the same es the applicable current range.
