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.
