Hyper Limit:
The Hyper Limit will be expressed in the unit of measure specified under the conversion
options with inches, feet, meters, PSI, etc., being common units for this field. As long as
the difference between the current scanned level and the last logged level is less than this
set hyper limit, the scan rate will stay at the regular rate. If the difference is greater than
the set hyper limit, the scan rate will jump to a faster preset scan rate.
Hyper Divisor:
The Hyper Divisor is used to determine the faster scan rate. The faster scan rate is
calculated by taking the regular scan rate and dividing it by the hyper divisor. The hyper
divisor must be able to be divided into the regular scan rate without a remainder or it will
default to 1. For example, if the regular scan rate is 1 minute, the following hyper divisors
are valid:
SCAN RATE HYPER DIVISOR FAST SCAN RATE
1 minute 60 1 seconds
1 minute 30 2 seconds
1 minute 20 3 seconds
1 minute 15 4 seconds
1 minute 12 5 seconds
1 minute 10 6 seconds
1 minute 6 10 seconds
1 minute 5 12 seconds
1 minute 4 15 seconds
1 minute 3 20 seconds
1 minute 2 30 seconds
1 minute 1 60 seconds
