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 at

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

-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:
