App

Index

• Range > Span_L, Span_U

Input range. The selectable range is displayed on the screen.

Note

• You cannot set the same value to

Span Lower and Span Upper.

• When the

Mode is 1-5V or Sqrt, Span Lower must be less than Span Upper.

• Range > Scale_L, Scale_U

Input range after converting the unit.
The selectable range is from –30000 to 30000. The decimal place is determined by

the

Scale Lower setting. It can be set to the following positions: “X.XXXX,” “XX.XXX,”

“XXX.XX,” “XXXX.X,” or “XXXXX.”

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 > 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.
