About Square Root Computation
The square root computation is as follows:

Each item is defined as follows:
： Span lower-limit value (Span L)
SPAN
L
： Span upper-limit value (Span R)
SPAN
R
： Scaling lower-limit value (Scale L)
SCAL
L
： Scaling upper-limit value (Scale R)
SCAL
R
：Input voltage
IN
： Output (Scaling value)
OUT

When an input value is 1 % or more (1 to 100 %)
OUT＝（SCAL

When an input value is less than 1 %
10×（SCAL
SPAN
OUT＝
Example) When makes setting in previous page, the display is as follow table
Input voltage (mV)
Display (%)
［Note］
The relation between scaling factor and displaying digit may stagger the accuracy rating.
