Note
• The DX converts the measured value to a value obtained by removing the decimal point
from the value span specified by Scale Lower and Scale Upper. For example, if the scale
setting is “–5 to 5,” the value is converted to a value within the span of “10”; if the scale
setting is “–5.0 to 5.0,” the value is converted to a value within a span of “100.” In this case,
the resolution of the value converted to a span of “10” is lower than the value converted to a
span of “100.” To prevent the display from becoming rough, it is recommended that the scale
be set so that this value is greater than 100.
• You cannot set the same value to Scale Lower and Scale Upper.
• When the Mode is 1-5V or Sqrt, Scale Lower must be less than Scale Upper.
• Range > Unit
Set the unit (up to 6 characters,
A a # 1
).
• Range > Ref. CH
The reference channel for difference computation.
• Range > Low-cut
Select On to use the low-cut function.
* The low-cut value for 1 to 5 V input is fixed to 0% value of the input span.
• Range > Low-cut value
On a square root computation channel, set the low-cut value in the range of 0.0% to
5.0% of the input span.
