For the procedure to set the functions, see section 1.10, “Function Setup Guide.”

• Bas

A given value (bias value) is added to the input value and used as the measured value

of that channel.

• Calbraton Correcton (/CC1 Opton)

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.

Burnout Detecton 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.

<Related Topcs> Setting the burnout detection function: Section 7.3

Reference Juncton Compensaton 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.
