Chapter 6 _______________________________________________________________ Calibration
One Point Calibration
CTA xx.xx yy.yy
xx.xx = current temperature
yy.yy = offset correction
Example of performing the offset calibration in one reference
temperature:
>CTA 21.2 2.3
>
Use an accurate and calibrated reference only.
Gain Calibration
CTA 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:
>CTA 0 0 101 -0.5
>
Example of performing the gain calibration in one reference point
without changing the offset at -70 °C:
>CTA -70 0 101 -0.5
>
Use an accurate and calibrated reference only.
