Error Notifications
The Measurements page reports all errors as shown in Figure 6-63: If there are no errors in
the current measurement cycle, the results are displayed as normal. Errors for the most
recent measurement cycle are listed first. Use the navigation buttons to move through the
various measurement cycles and examine any errors encountered in previous
measurement cycles.
Figure 6-63: PGA and Oxygen Sensor Error States
Errors are reported using a sequence of double-digit codes for the PGA and the Oxygen
sensor (if enabled). The PGA Error State denotes the most recent state within the
measurement cycle where the error occurred. All errors are listed as error codes and the
associated hexadecimal in brackets allows the most recent state to be identified. See
Section 6.15.1 for a definition of the error codes.
Note:
The Customer Service Centre requires both the state code(s) and error code(s) to
interpret any error.
For example, Figure 6-64 shows that the product has encountered two PGA errors. The
PGA Error code 04 denotes that there is an issue with the gas flow in the Main
Measurement state (23) and error code 13 denotes that the pump pressure is too low.
