Stored Faults
Information on stored faults is returned when requested. If no stored fault exists for a
given fault number, the words "NO Fault" will be returned instead of the normal
time/date status information.
The following symbols are commonly used to define the stored faults status commands:
•

Where:
x = < or > (data modifier to indicate that the sweep offset
value is less than or greater than the returned value).
s = + or - (sweep offset from center).
nnnnn = 0 to 35000.
yyy = OK or FLT (decoder lock status OK or FAULT).
Notes:
1. The 'x' (< or >) parameter is only returned if the level
has exceeded the computational resolution of the
system.
2. 'No Data' is returned if the level cannot be calculated.
3. 'Sampling' is returned if not enough data is currently
available to calculate the level.
