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

Burnout Detection of Thermocouples
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.

Reference Junction Compensation of Thermocouple Input
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.
Note
When using external reference junction compensation, set an appropriate reference junction
compensation voltage. For example, if the reference junction temperature of the external
reference compensation is T
0
°
C, set the reference compensation junction voltage to the
thermoelectromotive force of the 0
°
C reference of T
0
°
C.
