Parameters for Display
Prescaling
Set prescaling data to convert an input value into a desired displayed value.
Prescaling data can be freely set within a range of --9999 to 9999.

must be input (X: Input value, Y: Corresponding dis-
played value). When the 2-input operation mode is selected, the X and Y in-
put values must be values resulting from 2-input operation. X
1
or Y
1
can be
either larger or smaller than X
2
or Y
2
. If X
1
= X
2
, it is assumed that X
2
= X
1
+
1.
For example, in the case of adding A and B using two sensors, each of which
has an output of 1 to 5 V, input value X should not be set from 2 to 10 V but
from 2 to 5 V (0% to 50% input) for easier scaling. X
2
or X
1
cannot be be set
if the total sum of X
2
and X
1
exceeds
±
9.999V or 99.99 mA.

If (1 -- B/A) x 100 and B/A x 100 are selected, there will be no difference in
scaling between input A and input B, and the position of the decimal point will
be fixed between the second and third digits (i.e., 00.00). Consequently, the
result of operation will be displayed in a range of --99.99 to 99.99.
For the B/A of operating parameter 1, the operation of 1 -- (B/A) is required.
Scaling is possible.
The operation for the scaling result of the actual input value is as follows.
Example in the case of 4- to 20-mA input:
INA = 20 mA, INB = 12 mA
Scaling: X
2
= 20 mA, Y
2
= 100, X
1
= 4 mA, and Y
1
= 0
Then INA = 100 and INB = 50
Therefore, B/A x 100 = 50/100 x 100 = 0.5 x 100 = 50%
