9.1 Error Code Messages
Error Code messages appear on the screen while you are displaying 
measurements. When logs appear in graph form, errors are indicated by a 
vertical gray bar at the point of error. When they appear in a spreadsheet 
format, errors are indicated by their number, in place of the measurement. 
The Error Code messages are only general descriptions of the possible 
problems. Use Table 7 below to isolate and remedy the problem. If you are 
unable to remedy the problem, contact the factory.
Note:
We suggest that, in order to isolate the indicated problem more 
easily, you obtain a test flowcell. Contact the factory for details.
