Self-diagnostics
The system contains a complete self-diagnostic procedure that is executed automatically when the
sensor is in operation. The yellow LED is lit if an error is found. Sensors with display show a
wrench
if
an error is found. The wrench is shown and the yellow LED is lit during the first seconds after power
up and if the measuring range exceeded. They are automatically turned off when the sensor returns to
normal operation. The output OUT2 indicates the same information by setting the output voltage to 1V
or 2 mA.
Maintenance
The
eSENSE is basically maintenance free in normal environments thanks to the built-in self-
correcting
ABC
algorithm. Discuss your application with Senseair in order to get advice for a proper
calibration strategy.
