IM DL850E-01EN
Display Range (Upper/Lower)
To display the measured waveform on the screen, you need to set upper and lower display range limits that are
appropriate for the input.
Maximum Range:
• −5432 to 5432°C (when the resolution is 0.1°C)
• −5432 to 5432 K (when the resolution is 0.1 K)
The minimum span is 2°C (or 2 K).
Temperature Unit (Unit)
You can set the temperature unit to °C or K. The default setting is °C.

Reference Junction Compensation and Burnout (Temperature Setup)
Reference Junction Compensation (RJC)
The voltage produced by thermocouple is based on the temperature of the point that you are measuring and the
temperature of the reference junction. Reference junction compensation (RJC) refers to the act of correcting for
the temperature of the measuring instrument and using it as a cold junction.
On the DL850E/DL850EV, you can turn the internal RJC circuit on and off.
• ON: Select ON to use the RJC circuit to perform reference junction compensation.
• OFF: Select OFF to check measured temperature values or use an external reference junction (0°C).
Normally, you should perform measurements with RJC set to ON.
When you set RJC to OFF and apply a voltage that corresponds to a temperature t to an input terminal, if the
measured temperature does not match temperature t, the DL850E/DL850EV or the module may be damaged.

Burnout (Burn Out)
Sets the operation to perform when thermocouple detects a burnout (circuit break).
• ON: When a burnout is detected, the measured value is fixed at the upper limit of the measurement range of
thermocouple.
• OFF: Burnouts are not detected.
The default setting is OFF.
