3.2.3.4 Hyper-Delta Logging Mode Option
The Hyper-Delta Mode shown in Figure 3-8 is a combination of both the Hyper Mode and the
Delta Mode. The Hyper-Delta mode is probably the most versatile mode of measurement on the
market to date.
Logging Rate: Set between 1 second to 24 hours. This is just like in the Linear Mode.
Delta Limit: The Delta Limit sets the point that determines if the scanned data is to be logged
or not. Each time the sensor takes a reading, the “
W
ATER LOG's” internal
software computes the absolute difference between the last logged reading and
present reading. If the difference between the new value and the last logged
value is less than the Delta Limit, the sensor will not log the new data. If the
difference between the present reading and the last logged data is greater than the
Delta Limit, the new data will be logged.
Hyper Limit: The Hyper Limit will be expressed in the units 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
