Calibration procedures
Standard method
Includes these steps (see the following pages):
1.
Setting the low level and collecting Cal Low data*
2.
Setting the high level and collecting Cal High data*
3.
Collecting the linearizer table data*
4.
Calculating the linearity
5.
Calculating the calibration
* Perform these data collection steps in any sequence, depending on your
ability to empty and fill the vessel.
If using the standard method, it may be helpful to record the sensor counts
and levels at each step:
