The indicator will be ready to accept more scaling points
(if more are desired)
for multisegment linearization. The quantity and location of the linearization
points should be chosen very carefully to best utilize the segments available.
Refer to the section on linearization for a discussion on this matter.
At this stage, scaling is complete. The indicator will automatically calculate
the slope and offset of the display units. After completing Pro 1, it is
recommended that the scaling operation be verified by applying various signals
and checking the displayed reading.
PROGRAM NUMBER OF LINEAR SEGMENTS
This programming step loads in the number of linear segments desired for
multisegment linearization. If single slope scaling is desired, input
“1”
for this
step. If two segments are desired, input
“2”
, etc. You must have one more scaling
point known than the number of segments selected
(ie. 1 segment = 2 points, 2
segments = 3 points, etc)
. This step may be used to deactivate previously
programmed segments where lower segments would override higher segments.
(ex. changing “SEGt” from 5 to 3 causes slopes 4 & 5 to be replaced by an
extension of slope 3)
.
“SEGt”< >“1” - “9”
If
“1”
was selected, the indicator will return to
“Pro 0”
since scaling for the
first segment was already completed. Otherwise, a choice of either returning to
“Pro 0”
or commencing with the multislope linearization scaling is offered.
“SCALE” < > “yES”
“NO”
KEY-IN DISPLAY VALUE FOR POINT #3
If
“YES”
was selected, the display value for the third point is entered.
Otherwise, the indicator returns to
“Pro 0”
.
“dSP 3” < > “-99999” to “99999”
APPLY SIGNAL TO INDICATOR FOR POINT #3
The signal level value for point 3 is applied.
“INP 3” < > “0.000 to 5.000 Amps AC”
The sequence of entering display and signal values continues with
“dSP 4”,
“INP 4”, “dSP 5”
, etc. until the number programmed for
“SEGt”
is reached.
Upon completion, the indicator is scaled to the multiple segments. It is
recommended that the scaling be checked by exiting the programming mode and
applying signal values and verifying for correct display values.
* Note As the “UP” or “DOWN” button is continually held in, the display will
progressively increment faster until the fourth most significant digit is
changing at a rate of 1 number per second.
