Limit checking
Limit checking enables counter measurements to be compared on a
reading-by-reading basis to a lower limit and upper limit.
Limits that are exceeded are reported in the counter’s Questionable Data register
(bits 11 and 12). Register definitions and are contained in Chapter 8.
When enabled, limit checking appears on the counter display as shown in
Figure 6-4.
