Why does the Basic version of the AquaCalc 5000 firmware have four user-defined / non-standard meter constants instead of five?
The Basic version of the AquaCalc 5000 firmware has a problem with two line segment meter rating curves. The intercept value (the fifth constant) is a fixed value of 2.2 and cannot be changed by the user. This two-segment feature was originally intended to be used only with ice-meters having a two-segment curve and a cross-over of 2.2. Please see the revised Basic firmware instructions for Using Non-Standard / User-Defined Meters for more information. You may contact Customer Support for information on an upgrade that will fix this problem.
