Selecting Error Handling -
ERROR (cont.)
9. Press [X] to activate or deactivate two-path error handling and
press [ENTER]. The
2PATH ERROR HAND option is intended for
applications where two sets of transducers are installed in the
same location in the same pipe to improve accuracy and the meter
is operated in
AVE mode. With this function enabled, the Model
AT868 performs error handling only if both
channels/paths are in
error. If this function is disabled, error handling occurs when
either
channel/path goes into error.
Specific responses of the display and the totalizer to the two-path
error handling option available at the above prompt are listed in
Table 2-6 below.
Procedure Options After completing the above steps, the user program returns to the
Global I/O window. Do one of the following:
• To continue regular programming, refer to Appendix A, Menu
Maps, to navigate to the desired menu.
• To leave the user program, press [ESC] four times.
