The maximum number of commands by message is 15. 
 
NOTE :be careful not to put together standardised commands with other ones. 
 
When a event like transmission error,end of test, safety loop open, ...,occurs during the measurement 
, the controller could be informed by a SRQ. 
To activate this function, you must send a SRQ command just after the initialization of the unit. 
On event, you could read the internal registers of the IEEE controler ( STB,SRE,...) to get more 
precise reasons why. 
 
 
If the message is not recognized by the unit, the error message <DIALOG ERROR : 1> is displayed  
 
If the code is out of context, the error message <DIALOG ERROR: 2> is displayed 
(special code for a function when the function was not selected or  numerical value out of range)
