THE A-2000 DIAGNOSTIC PROCEDURES
The A-2000 has three built-in diagnostic procedures:
•
Power-Up
•
Automatic
•
Manual
These procedures check the A-2000 unit’s operability and report software and hardware
malfunctions.
The power-up diagnostics run automatically each time you turn on the A-2000 unit. These
procedures check the software (FLASH), system memory, speaker, display, serial ports,
timer/counters, FPGA, BIS Engine, real-time clock, Data Memory and Setup Memory.
The automatic diagnostics run continuously in the background while the unit operates.
These procedures check the Digital Signal Converter for the following conditions:
interface faults, disconnect, lead off and power faults. The automatic diagnostics also
check for problem states within the BIS Engine and printer and can be used to check for
impedance.
The manual diagnostics are operator initiated using the A-2000 keys and menu choices.
These procedures check for the proper functioning of the Digital Signal Converter, the
display, and all BIS processing circuits.
Note:
The diagnostics can be run safely while the patient is connected to the A-
2000 unit; however, running the diagnostics will temporarily disrupt
monitoring. Do not run DSC self test during electro-cautery as it may
erroneously indicate a failure.
6.2.1
Power-Up Diagnostics
To run power-up diagnostics, turn the unit on using the ON/OFF button on the lower
corner of the unit. Two screens will be displayed successively on the display. The first
screen contains the following information:
