About Square Root Computation
The square root computation is as follows:
Each item is defined as follows:
SPAN
L
: Span lower-limit value (Span L)
SPAN
R
: Span upper-limit value (Span R)
SCAL
L
: Scaling lower-limit value (Scale L)
SCAL
R
: Scaling upper-limit value (Scale R)
IN
: Input voltage
OUT
: Output (Scaling value)
When an input value is 1 % or more (1 to 100 %)
OUT
=(
SCAL
R
-
SCAL
L
)× +
SCAL
L
When an input value is less than 1 %
OUT
= ×(
IN
-
SPAN
L
)+
SCAL

Example) When makes setting in previous page, the display is as follow table.
Input voltage (mV)

[Note]
The relation between scaling factor and displaying digit may stagger the accuracy rating.
