Sensor response
Description
The error report contains information on errors that have occurred during the operation of the
sensor. The output string is always comprised
of 15 ASCII characters (all shown as ‘0’, ASCII
30(HEX) in the above example).
The first character in the data field represents the current operational status of the sensor
. ‘0’
(ASCII 30(HEX)) indicates that the sensor is functioning correctly any other character
indicates that an error condition exists. The status is cleared once the ER command is
executed.
The next 14 locations contain an historical log of the last 14 errors with the most recent error
being recorded in the leftmost position. Each error condition is assigned an ASCII character.
The historical log is stored in Flash and is retained when the power is switched off or the
sensor software reset.
This report can be sent back to the FT factory for analysis if there are problems with the
sensor.
