MINITRAC 31 • 4 … 20 mA/HART - four-wire

Enter now the corresponding density value (g/cm
3
).
You thus assign a corresponding density to the actual count rate.
Note:
If possible, take a product sample and determine the density simulta-
neously in your sampling position.
It has proven marking the product smaples with date and respec-
tive count rate. Hence the values can be assigned later on without
problems.
Accept the value pair with "
OK
".
Enter as many linearization points as possible. You can influence
the accuracy of the density measurement by doing this. The more
linearization points you enter and the higher the difference between
the density values, the more reliable the measurement.
Value pairs that are not yet complete, e.g. due to a missing density
determination, can be edited later with the function "
Setup/Lineariza-
tion
" under the item "
Change/Edit
".
A maximum of 32 linearization points is possible.
Note:
If you cannot change the medium during the adjustment process, it
is possible to carry out the linearization with only one point. However,
you should enter further linearization points later, if possible.
