PLEASE NOTE!
The sensor accuracy is defined at continuous operation (at least 3 weeks after
installation)
Self-diagnostics
The system contains complete self-diagnostic procedures. A full system test is
executed automatically every time the power is turned on. For
aSENSE
mIII
the
internal voltage regulators and outputs are checked. In addition, constantly during
operation, checking the valid dynamic measurement ranges checks the sensor
probes against failure. These different system checks return error bytes to the
system RAM. If any error is detected, the yellow LED will be lit
until the error has
vanished and the error flag is reset. “Warm up” and “Out of Range” are the only bits
that are reset automatically after return to normal state. All other error bits have to be
reset manually after return to normal state
– either by pushing MENU & ESC buttons
simultaneously for (=Entr(+-) or by power off and restart.
By pushing the push button ”MENU” the error code
number Exxx
is shown on the
LCD
.
Descriptions of the different codes are listed below.

Out of Range Error
Accompanies most of other errors.
Can also indicate overload or failures
of sensors and inputs.
Resets automatically after source of
