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