Honeywell DR4300 用户手册

Recorders with displays run background tests as described in Section 8 – Troubleshooting and Pen 
Alignment of Recorders with Display to verify data and memory integrity. If there is a malfunction, an error 
message will blink in the lower display. If more than one self-diagnostic test fails, the display will cycle 
through the appropriate error messages.    

A list of background test error messages is in Table 4-28.  

If any of these error messages are displayed, refer to Section 8 for information on correcting the problem. 

In addition, an error message will be displayed if the operator tries to run a setpoint program in which the 
number of the ending segment is lower than the segment number of the start segment.  See Appendix C for 
details.
