• Bias
A given value (bias value) is added to the input value and used as the measured value
of that channel.

• Calibration Correction (/CC1 Option)
Corrects the measured value of each channel using segment linearizer approximation
and makes the resultant value the measured value of the channel. You can set
arbitrary correction values for 2 to 16 points of arbitrary measured values. Linear
approximation is used between two segment points. Correction values can be
assigned using revise values or absolute values.

This function makes the recording go off the scale to the right or left when the
thermocouple burns out while measuring temperature with a thermocouple. This function
can also be used on 1-5V. The burnout detection function can be set for each channel.
By default, this function is disabled.
Note
For 1-5V, a burnout occurs when the input value is less than or equal to 0.2 V.
<Related Topics> Setting the burnout detection function: Section 7.3
When measuring the temperature using a thermocouple, the reference junction
compensation on the recorder can be used. When using external reference junction
compensation, you can set the reference voltage. The reference junction compensation
can be set for each channel.
By default, the recorder is configured to use the internal reference junction compensation
function.
For the procedure to set the functions, see section 1.10, "Function Setup Guide."
