2. In
the
Point #2
field, enter the second
Reference Value
and the corresponding
Logger Value
.
Note:
If you are using a calibrator and the logger is currently
displaying the real value to be calibrated, press the
Copy
button to copy the real value to the
Logger Value
text box.
3. Press
Send Calibration
to send these values to the
logger memory.
4. Compare the real value in the Logger Data pane to the
reference value. If the values are within an acceptable
margin of error you may close the Calibration window, or
move on to the next sensor or input.
5. If the values are still not accurate enough, you can
perform Offset calibration to tweak with values further.
Note:
Fourier strongly recommends calibrating using the
default Reference values that appear in the two Reference
value text boxes for each sensor.

Performing an Offset
Calibration
If, after the Two-point calibration procedure, the logger still
exhibits some offset value use the Offset calibration tool to
correct it.
The offset value is the difference between the value displayed
by the DataNet logger and the reference value. For example if
the calibrator is set to 0 °C and the logger reads 1 °C the
offset value is
+
1, but if the logger reads
−
1 °C then the offset
value is
−
1.
To perform an Offset calibration, simply select the
Offset
calibration
radio button to enable the
Offset
text box. For
