Product Calibration (Calibration with Sampling)
When the sensor cannot be removed – e.g. for sterility reasons – its slope can
be determined with “sampling”. To do so, the currently measured process value
is saved by the Protos. Directly afterwards, you determine a reference value
using a portable meter, for example. Then, you enter this reference value into
the process analysis system.
During calibration the module is in function check (HOLD) mode.
Current outputs and relay contacts of the module behave as configured
(BASE module).
NOTICE!
The reference value must be measured at temperature and pressure conditions
similar to those of the process.
