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.
