COLD JUNCTION COMPENSATION SENSOR(RJC)
Attachment :  To monitor output connector (1piece/module)
Compensation accuracy :  ±1°C at 25°C

MEASURE
Mode : Direct, Composite, Differential
Direct         : Direct temperature
Composite    : Average temperature of the selected input channel
(If the number of the selected input channel is one,
the value of Composite is the same as Direct.)
Differential    : Temperature difference obtained by subtracting
Composite from Direct
Note）
・Composite and Differential can be enabled/disabled by the setting.
・Input channels to be selected for Composite can be set by the channel,
but they must be from the same slot.
・To the recorder output and the output via Modbus communication,
users can assign one of the modes above.
・When this monitor is used for intrinsically safe explosion proof construction, the
OK alarm set point may fall within the range, depending on the input
transducer and the specified monitoring range.
