VA3000 DIAGNOSTICS

2.0 DIAGNOSTICS

The VITALERT 3000 Series contains a diagnostic system that monitors certain system functions and records their operational status. A series of tests is performed when the instrument is powered up and the results are displayed on the diagnostics screen shown in Figure 2-1. If any of these tests fail, consult Section 3 for proper corrective action.
The operational status of the VITALERT 3000 Series is shown at the end of the power-up self-diagnostics and will be one of the following:
FUNCTIONAL: All self-diagnostic tests pass, and the instrument begins normal
monitoring operation.
CONDITIONALLY A non-critical fault has been detected, and the MONITOR key FUNCTIONAL must be pressed to continue operation. The instrument may
continue to be used in this situation, but steps shall be taken to eliminate the problem.
NON-FUNCTIONAL: The self-diagnostic tests reveal a problem in the instrument. A
summary of the diagnostic results is posted and normal operation is inhibited. The instrument cannot be operated until the problem is corrected.
Further diagnostic functions are available through service screens that can be accessed as described on the following pages. If no display is present upon system power-up, refer to Section 3 of this manual for troubleshooting assistance.
