Explanation
Thermocouple Type
Select the type to match the thermocouple that you are using.
Select the thermocouple type from the list below.
When the input terminal is open, the displayed value is set to a value less than or equal
to the lower limit of the measurement range.

Temperature Unit
Select the temperature unit from
°
C and K. The default setting is
°
C.
Displayed Range
To display the measured waveform, the upper and lower limits need to be set according
to the input.
Selectable Range
–5432 to 5432

–5432 to 5432 K (resolution: 0.1 K)
The minimum span is 2
°
C (or 2 K).
Reference Junction Compensation (RJC)
The SL1400 normally performs reference junction compensation with the built-in RJC
circuit when measuring temperature with the thermocouple. The SL1400 allows you to
turn ON or OFF the internal reference junction compensation.
Normally, turn it ON.
ON
Select this setting to enable the reference junction compensation by the internal RJC circuit.
OFF
Select this setting when checking the temperature measurement value or when using an external
reference junction (0
°
C).
Note
If a voltage corresponding to a certain temperature t is applied at the input with the RJC turned
OFF and the measured temperature does not match temperature t, the instrument may be
damaged. In this happens, contact your nearest YOKOGAWA dealer.
Burnout
Specify the behavior when the thermocouple input detects a burnout. By default, this is
set to OFF.
ON
Fix the measured value to the upper limit of the measurement range of each thermocouple if a
burnout is detected.
OFF
Not detect burnouts.
