8.1 Summary
When a calibration curve changes at the sample
temperature Ts, this function enables to change the
calibration curve to other one at this sample
temperature. For the input of the sample
temperature, a platinum resistance thermometer
(Pt100), a radiation thermometer or
a
temperature/voltage converter with the output of 4
to 20mADC can be used. By utilizing this function,
10 calibration curves in one group (9 curves only
in the group 10) are changed with the sample
temperature Ts. Since 99 calibration curves can be
stored, up to 10 groups can be set.
8.2 Model
This is an optional function. The model number of the detector unit with this optional function
is as follows:
IR-M2
External input
5: Correction input 4 to 20Ma
8: Correction input Pt100
Communications
S: RS-485
R: RS-232C
8.3 Wiring of detector unit
8.4 Setting of dipswitch (Ref to [3.1 Setting of dipswitches])
(1) Turn off the power supply of the detector unit and the setting display unit.
(2) Switch the dipswitch 7 (Correction input enable /disable ) of the detector unit to ON side.
(3)
For 4 to 20mA input:
Switch the dipswitch 8 (Correction input) to OFF side
(4 to 20mADC).
For Pt100 input :
Switch the dipswitch 8 to ON side (Pt100).
(4) Turn on the power supply of the detector unit and then turn on the power supply of the
setting display unit.
