18.5.3 Adjustment of the resistance thermometer input range
Connect as shown in “18.4 Connection (2) In case of the resistance thermometer input”. Execute the
adjustment by inputting the resistance value for the adjustment range.
(1) Click the “Go” button at the range to be adjusted.
(2) Since the window indicating the resistance value for inputting is displayed, input its value to this
recorder.
(3) Adjust the zero point.
(Example) For the adjustment of the Pt150 range
Input the resistance of 100 Ω with the standard variable resistor.
(4) After inputting the zero point for about 5 seconds, click the “Go” button.
(5) Adjust the span point.
(Example) For the adjustment of the Pt150 range
Input the resistance of 157.33 Ω with the standard variable resistor.
(6) After inputting the span point for about 5 seconds, click the “Go” button.
(7) After the adjustment of the span point, the screen is returned to the calibration screen for all ranges.
(8) Repeat from (1) to (6) for the adjustment of other ranges.
* When the channel to be calibrated is kept being open, the adjustment at this channel is not
performed.
18.5.4 Adjustment of the thermocouple input range Adjustment of the reference junction
compensation (RJ at 0°C)
Connect as shown in “18.4 Connection (3) In case of the thermocouple input”. Execute the adjustment by
connecting the thermocouple for adjusting to each of the 1
st
, 6
th
and 12
th
terminals.
(1) Before moving to the calibration screen, set the input of the 1
st
, 6
th
and 12
th
terminals to the
followings.
(Refer to “13.2.1 Setting contents”.)
Range type Thermocouple connected
Range
Set 1 for the decimal point position of the range setting value.
Recommendation
: Measuring range of which the reference range is
±13.8mV and the display resolution becomes 0.1°C (Refer to “ 21 8
Specifications Measuring Range, Accuracy Rating and Display
Resolution”.

After the adjustment of the DC voltage input range, execute the adjustment of the thermocouple
input range. If the adjustment of the DC voltage input range is performed after the adjustment of the
thermocouple input range, the adjustment results are influenced.
