Index
Input (Mode, Range/Type, and Span)
Set the input type (Mode, Range/Type) and the recording span (Span).
Mode Relevant Settings
VOLT (voltage) Range/Type, Span L, and Span R
TC (thermocouple) Range/Type, Span L, and Span R
RTD (resistance temperature detector) Range/Type, Span L, and Span R
1-5V (1-5V) Range/Type, Span L, and Span R
DI (voltage level/contact input) Range/Type, vpan L, and Span R
SKIP (Measurement OFF) None
Note
• Click the Default button ( ) for Span L to set the minimum value within the measurable
range. Click the Default button for Span R to set the maximum value within the measurable
range.
• The span L and R values that have been changed are displayed in orange, but the values
are valid. When data adjustment (see section 2.8) is executed, the values change back to
white.
• When a value outside the measurable range is entered or when the span L and span R
values are set to the same value, they are corrected when the data is checked.
• If SKIP is selected, other settings are discarded.
Delta Computation (Delta and RefCh)
Measures the difference between the input value of its own channel and that of the reference
channel. Delta computation can be specified when the Mode setting is VOLT, TC, or RTD.
Delta/Scale/Sqrt
Select DELTA.
RefCh
Select the reference channel.
Specify a channel that is smaller in channel number than itself for the reference channel.
Square Root Computation
The square root of the input value is calculated, the result is scaled to a value in the
appropriate unit, and used as the measured value of the channel. Also, the low-cut function
can be used. This setting can be used only when the input mode is set to VOLT.
Delta/Scale/Sqrt
Select SQRT.
Low-cut
This appears when low-cut is enabled (see page 2-25) in Basic Setting mode.
For Square Root Computation
ON: Sets measured values below the specified value to 0 (the leftmost value of
the scale).
Value (%): The measured value to be low-cut. Set the value in the range of 0.0% to 5.0%
of the recording span.
For 1-5V Input
ON: Sets measured values below 0% input to 0 (the leftmost value of the scale).
Linear Scaling
Scale (Point, L, and R)
The input values are scaled to values in the appropriate unit to be used as measured
values. Set the leftmost value of the scale (L) and the rightmost value of the scale (R)
using a mantissa and decimal point position.
Mantissa:
–20000 to 30000
Decimal position: 0 (the number of digits right of the decimal is 0) to 4 (the number of
digits to the right of the decimal is 4)
