6.2.2 Calibration
One-point calibration can be carried out for preliminary adjustment of the measuring
ranges to the reading. Two- or multi-point calibrations have to be performed for accurate
and final adjustment. Different procedures are required, depending on the selected cali-
bration method. For more information on the calibration methods see chapter 8
CALIBRATION.
One-point calibration has to be performed if only one value pair is available or the value
pairs are close together. Enter an absorption coefficient as a1-value; for common prod-
ucts, this value may be taken from the table in the Appendix. The calculation formulas
for other products are listed in chapter 8 CALIBRATION.
Please read chapter 8 CALIBRATION in any case before performing calibration!
Prerequisite: Pipeline must be filled completely or level in container must be at least
200 mm above the measuring point.
Select menu Calibrate / Live Display with <more>.
Push <sk1> to call the Calibrate submenu.
Select product.
Specify if it is a suspension measurement.
Select unit.
Push <sk1> to select the Data input submenu.
Deselect Calibr. Data transfer with “No”
Read in 1. Rate: cursor appears in the row “1. Rate = cps”.
Push <run>. Count rate and temperature (if a temperature sensor is connected) are
read in. Wait until the measured value has become stable (20 to 50 s). While reading-in
the count rate, the density of the products must not change.
While reading in the count rate, take a sample of the product from the pipeline and de-
termine its density or concentration.
