Calibrate
Product Selection
No. 1/2/3/4:
Enter the product number for the calibration product and confirm with <
enter
>.
Suspension measure Yes/No
If you select Yes the Solids density and Liquid density parameters are taken into
account in the calculation (see also section 6.5 Measurements of Suspensions
and Solutions).
Select Unit
g/cm³, t/m³, Bx, Weig.%, Be, g/l
Select the unit of measure for density and concentration measurements. For
calculation of the calibration curve, the values are converted into g/cm³. How-
ever, the results are always displayed in the selected unit.
sk1: Data input
Enter the calibration data for the requested number of calibration points.
Calibr. Data transfer
Select "Yes" to use the calibration data of another product and then enter the
product number whose data you want to use. Then run through Rate 1. To Rate
10. and correct them if necessary.
1. Rate to 10. Rate
You need at least 2 calibration points (except for one-point calibration, see sec-
tion 6.2 Calibration Method). You have to run through all 10 points. Calibration
points with zero values are not calculated.
The values can be entered or read in by pressing the <
run
> button. In the latter
case, the countrate and – if a temperature sensor is connected and instrument
configuration with temperature compensation has been selected – the actual
product temperature is read in. As soon as the measured value is stable, press
the <
run
> button again to stop the reading-in process. Press the <
enter
> button
to confirm the read-in or entered value.
Rate: Countrate in cps read-in or entered.
Density: Enter the density value determined in the lab.
Temp: Only for temperature compensation: read in temperature.
Otherwise, this parameter is not relevant.
