Chapter 6 _______________________________________________________________ Calibration
If the stabilization of the sensor to the temperature of the reference needs
to be monitored, the measurement output can be repeated with <cr> at
Ref1 and Ref2:
>CTA <cr>
T : 23.19 Ref1 ? <cr>
T : 23.20 Ref1 ? <cr>
.
.
.
T : 23.22 Ref1 ? 23.3 <cr>
Press any key when ready ...
T : 101.42 Ref2 ? 101 <cr>
One Point Calibration
CT xx.xx yy.yy
xx.xx = current temperature
yy.yy = offset correction
Example of performing the offset calibration in one reference
temperature:
>CT 21.2 2.3
>
Use an accurate and calibrated reference only.
Gain Calibration
CT xx 0 yy.yy zz.zz
xx = temperature in which there is no changes in offset
yy.yy = current temperature
zz.zz = correction (T
ref
-T
measured
)
Example of performing the gain calibration in one reference point
without changing the offset at 0 °C:
>CT 0 0 101 -0.5
>
Example of performing the gain calibration in one reference point
without changing the offset at -70 °C:
