When the pump is switched on with a disposable syringe extension set fitted, the user is
alerted that an auto zero has not been carried out.
An alarm is generated if an extension set calibration is unsuccessful.
A range of 0 to 1000 mmHg is specified for the extension set, with an offset of +/-100
mmHg. If this offset is exceeded, an unsuccessful calibration alarm is generated.
If the extension set is removed from its housing while the pump is running an alarm condi-
tion will be activated.
When under the control of an external computer, an alarm is generated if a computer failure
or disconnection is detected.

The 3200 self tests include the following:
• ROM test (CRC-16),
• RAM test,
• power supply voltage test,
• keyboard test (this test checks for shorted keys),
• stack usage test, and
• motor windings continuity test.
The program is held in a 256 Kbyte EPROM.
The configuration data and settings are stored in the processor’s EEPROM.
A 32 Kbyte RAM chip holds the history. The history will be lost if the AC supply to the pump
is switched off or disconnected and the internal batteries unplugged.
