APPLY SIGNAL TO INDICATOR FOR SCALING POINT #2
The meter will indicate the actual amount of signal being applied to the input.
However, the indicator still retains the previous value until “P” is pressed, at
which time the current value is stored. Pressing either the “UP” or “DOWN”
button causes the previous value to remain programmed in the unit.
“INP 2” < > “+/-20000” (ex. 20000)
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.
If the totalizer/linearizer option is installed, the indicator, instead of
completing Module #1 and returning to “Pro 0”, will be ready to accept more
scaling points 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.
PROGRAM NUMBER OF LINEAR SEGMENTS
This programming step loads in the number of linear segments desired for
multisegment linearization. If just single slope scaling is all that 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
de-activate previously programmed segments where lower segments would
override (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” < > “+/-20000”
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 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.
