SELF DIAGNOSIS
The system contains complete self-diagnostic procedures that are executed
automatically when the sensor is in operation. Sensors with displays show a
wrench if an error is found. The wrench is shown during the first seconds after pow-
er up and if the measuring range is exceeded.
MAINTENANCE
The AST-IS14 is basically maintenance free in normal environments thanks to the
built-in self correcting ABC algorithm. Discuss your application with your distributor
in order to get advice for a proper calibration strategy.
PLEASE NOTE
The sensor accuracy is defined at a continuous operation (at least 3-weeks after
installation).
