Scale Upper –999999 to 999999 100.00
Unit
Character string (up to 6 characters, A a # 1 ) —
1 Appears when math is set to Linear scaling or Square root.
Decimal Place
Set the decimal place of the scale for linear scaling and square rooting.
Span Lower, Scale Upper
Assign values to the results of unit conversion of linear scaling and square rooting.
Note
• The GX/GP converts measured values to values within the range set by the Scale Lower
and Scale Upper values with their decimal points removed. For example, if the scale setting
is “–5 to 5,” values are converted to values within the span of “10”; if the scale setting is “–5.0
to 5.0,” values are converted to values within a span of “100.” In this case, the resolution of
values converted to a span of “10” is lower than those converted to a span of “100.” To prevent
the display from becoming coarse, it is recommended that the scale be set so that the span is
greater than 100.
• You cannot set the same value to Scale Lower and Scale Upper.
Unit
Set the unit.
Low-cut 1
Setup Item Selectable Range or Options Default Value
On/Off Off, On Off
Low-cut value 2 0.0% to 5.0% 0.0
Low-cut output 3 Output 0%, Output linear Output 0%
1 Appears when the type is set to Volt and Calculation is set to Square root or when the type is
set to GS and Calculation is set to Linear scaling or Square root.
2 Appears when On/Off is set to On.
3 Does not appear when the type is set to GS and Calculation is set to Linear scaling.
On/Off
Select On to use the low-cut function.
Low-cut value
Set the low-cut value in the range of 0.0% to 5.0% of the input span.
Input value
Measured value
Result of square root computation
Low-cut value
Low-cut output
Set the output value when the input is less than the low-cut value for when the low-cut
function is in use.
Options Description
Output 0% Set the value for 0%.
Output linear Outputs values that result by applying linear scaling to the input on the basis of
the specified span and scale.
Note
When the type is set to GS and Calculation is set to Linear scaling, the low-cut output is fixed to
Output 0%.
