Input Type (Mode and Range/Type)
Select one of the following from the pull-down list.
Mode
Relevant Settings
VOLT (voltage)
Range, span L, and span U
TC (thermocouple)
Type, span L, and span U
RTD (resistance temperature detector)
Type, span L, and span U
DI (voltage level/contact input)
Range, span L, and span U
SKIP (measurement/display OFF)
None
Note
• When a value outside the range is entered or when the span L and span U are set to the
same value, they are corrected when the data is checked.
• If SKIP is selected, settings such as Delta/Scale/Sqrt and Range/Type are disabled.
Difference Computation and Reference
Displays the difference between the input and the reference channel.
If difference computation is performed between channels that have different range and
type settings, the decimal place of the result is set to that of the channel computing the
difference. If the number of decimals of the reference channel is greater than that of the
channel computing the difference, the reference value below the least significant digit of
the channel the difference is rounded down beforehand.
Square Root
Computes and displays the square root of the input. This setting can be used only when
the input mode is set to VOLT. As necessary, set the span, scale, and unit.
Display Span
Sets the upper and lower limits (full scale) of the display.
When the span L and span U are set to the same value or when a value outside the
range is entered, they are corrected when the data is checked.
Scale
Scale L, scale U, and Decimal Point
The scale value is displayed by taking the range between scale L and scale U to be the
full scale. Enter the upper and lower limits to which you want to convert the raw values.
Include the decimal point.
When the scale L and scale U values are set to the same value or when a value outside
the range is entered, they are corrected when the data is checked.
Unit
Enter the unit using up to 6 alphanumeric characters.
