Scale electronic unit (NSW)
(Event Status Register)
Faulty entries through the interface are acknowledged by the WE2108 with ?CRLF (see Sec-
tion 2.2). In the scale mode or on parameter entry further errors which are independent of
the type of operation (keyboard or computer command) can occur. These errors are identi-
fied by two−digit code numbers and displayed for 3 seconds in the display (e.g. Err12 ).
This error status can also be queried through the interface with the ESR command. In this
case it is immaterial whether the error was triggered by a preceding command or by manual
operation. The query ESR?; then delivers only an error code if a message ("Err12" ) is dis-
played in the display at the time of the query. The answer is then the same as the error num-
ber (here: 12CRLF), otherwise it is 0CRLF.
The query can either be made at regular time intervals or following commands the execution
of which can lead to errors.
Examples:
The meaning of all error codes (1..99) is described in the WE2108 operating instructions.
