ThermocoupleInput

Set the function that detects burnouts in the sensor for thermocouple input and 1-5V

input and the referencejunctioncompensationmethodofthethermocouple.

SetupScreen

Press MENU (to switch to setting mode), hold down FUNC for 3 s (to switch to basic

setting mode), and select the Menu tab > Burnout,RJC.

SetupItems

• First-CH/Last-CH

Select the target channels.

• Burnoutset>Mode

Detects thermocouple and 1-5V input sensor burnouts.

Settings Description

Off Does not detect burnouts in the sensor.

Up When the sensor burns out, the measured result is set to +over range. The

measured value displays “Burnout.”

For 1-5V input, the DX assumes that the sensor has burned out when the

measured value exceeds the scale upper limit by 10% of the scale width.

(Example: When the measured value is greater than 110 when the scale is from

0 to 100)

Down When the sensor burns out, the measured result is set to –over range. The

measured value displays “Burnout.”

For 1-5V input, the DX assumes that the sensor has burned out when the

measured value falls below the scale upper limit by 5% of the scale width.

(Example: When the measured value is less than –5 when the scale is from 0 to

100)
