This is a current, but partial, list of error messages which the logger can produce when responding to issued commands. Each error message begins with Ennnn, where nnnn is a 4-digit decimal number, padded with leading zeroes if necessary. 

The number allows host software to interpret the error code as desired if the rather terse messages from the logger are unsuitable for any reason.

Note that some messages may be followed by variable elements not shown here. The following errors have been categorized in what is relevant to a misuse of the command set (wrong usage) and what is due to an hardware failure or a factory misconfiguration.
In case of an hardware failure, one course of action is to apply a full hardware reset (see Tips for system integrators).
