Measured value on the reference channel
–
The measured value of the channel is set to the
difference with respect to the measured value of the
reference channel.
Converts the unit to obtain the measured value. Takes the square root of the input value and converts
the unit to obtain the measured value.
Corrects the input value with the characteristics
specified by segments to obtain the measured value.

Note
You can use difference computation even if the reference channel and difference computation
channel’s input types and ranges are different. Difference computation takes place using the
difference computation channel’s decimal place and unit.
Example 1: If the input value of the difference computation channel is 10.00 and the measured
value of the reference channel is 100.0, the result is 10.00–100.0=–90.00.
Example 2: If the input value of the difference computation channel is 10.00 V and the
measured value of the reference channel is 5.00 mV, the computed result is 10.00
V – 5.00 mV = 5.00 V.
