The totalizer will totalize up to 999999
(999,999 Pound-Hours)
.
* This value is normally 1, but can be used as a coarse scale factor of 60 or 3600.
** Since the time period is in Hrs., the selected T.B. is 3600 (Program Select
Value = 2) which equals per hour (3600 sec.)
LINEARIZER
The linearizer feature is a series of programmable scaling points that are
used to construct linear segments to linearize the input signal. The most
common application would be to linearize strain gages. Correction for
non-linearity is accomplished by continuing with scaling points beyond
“DSP
2”
and
“INP 2”
in
“Pro 1”
or
“Pro 2”
, with
“DSP 3”
, and
“INP 3”
,
“DSP 4”,
and “INP 4”
, etc. The unit automatically calculates the linear segments
between the programmed coordinates. This process of entering linear segments
is also known as
“curve fitting”
. A maximum of nine segments are available.
No restriction is placed on the ordering of the scaling points as long as the input
signal scaling points are all increasing or all decreasing. To have one or more
points
“back-track”
, the input/output
(signal/display)
relationship would not
be a function and would be undefined in that area. Additionally, consideration
should be given to the location and length of each segment to fully minimize the
segment conformity error over the desired range.
