Error analysis
The calculator continuously monitors its own operation and displays various error messages. The error
code is displayed in the main loop if an error occurs. The permanent display shown corresponds to the
“normal” display (e.g. a temperature sensor error is not shown in the flow rate display). In the basic
display mode, the display changes between error codes and the basic display (exception: error display
“C - 1” is shown permanently). All the other windows can still be selected by pressing the button.
The error display disappears automatically as soon as the cause of the error has been cleared. All
errors present longer than 6 minutes are saved in the error log.
The following table shows the error codes indicated in the display with their respective meaning:
