18.5.3 Adjustment of resistance thermometer input range
Connect as shown in “18.4 Connection
(2)
In case of the resistance thermometer input”.
In case of the KR21*0, execute the adjustment by inputting the resistance value for the adjustment range
of each channels of CH2, CH5, and CH11.
In case of the KR21*1, execute the adjustment by inputting the resistance value for the adjustment range
of CH2.
(1) Select “Go” at the range to be adjusted, and press the ENTER key.
(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, press the ENTER key.
(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, press the ENTER key.
(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.
(9) In case of the KR21*0, after adjustment of each channels of CH2, CH5, CH11, press the ESC key
for retuning settings menu screen. In case of KR21*1, after adjustment of CH2, press the ESC key
for retuning settings menu screen When the channel to be calibrated is kept being open, the
adjustment at this channel is not performed.
18.5.4
Adjustment of thermocouple input range…Adjustment of the reference junction
compensation (RJ0
ºC
)
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 CH1, CH6 and CH12 terminals.
(1) Before moving to the calibration screen, set the input of the CH1, CH6 and CH12 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 “
20
8
Specifications Measuring Range, Accuracy Rating and Display
Resolution”.)
ＲＪ
Internal
Burnout
None
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.
