4.8.2 The Curve Algorithm Screen
The Curve Algorithm is a linearization method. It provides from 1 to 9
intermediate points between the ZERO and SPAN values, which can be
normalized during calibration, to ensure a straight-line input/output transfer
function through the analyzer. (Before setting the alogorithm curve, each
range must be Zeroed and Spanned).
Each range is linearized individually, as necessary, since each range
will usually have a totally different linearization requirement.
To linearize the ranges, you must first perform the four steps indicated
at the beginning of section 4.8 Programming. You will then be in the MAIN
MENU and select ALOGORITHM.
