If the Accutracker DX NIBP is being used with the transmitter, perform the
Accutracker DX NIBP operational tests.

Additional system tests
Power-up self-tests
Transmitter
The transmitter performs a limited amount of testing of the internal memory
components when it powers up. The results of these tests are indicated by the LEDs
on the transmitter case. Test results may also be viewed on a remote terminal or
personal computer if the ApexPro transmitter programming box is connected and in
use.
To start the tests, install new batteries into the transmitter. The internal digital signal
processor performs the self-tests automatically.
NOTE
Any test failures are stored and appear when you view TTX information during
programming of the transmitter. Stored errors can only be cleared by
reprogramming the transmitter.
The following functions are performed at power-up of the transmitter.
1.
First, a memory test is performed. The memory in the transmitter’s digital signal
processor circuit either passes or fails this test.
EEPROM memory is copied to RAM memory.
The copy is verified with a checksum test.
If the checksum test passes, testing continues.
If the checksum test fails, a checksum error is logged and the memory test is
repeated. This test continues in a loop as long as the test fails and power is
applied to the transmitter, indicated by all LEDs flashing rapidly then
pausing repeatedly.
The Checksum Error status is displayed in the power-up self-test results of
the Apex & ApexPro Tx Config program for programming the transmitter.
2.
Next, the transmitter’s frequency synthesizer is programmed with the specified
customer’s frequency. A test is performed to verify a successful lock of the
synthesizer circuits.
If the synthesizer lock test passes, the transmitter starts normal operation.
If an error is detected, the transmitter creates a Synthesizer Lock log which
indicates if the transmitter was ever unable to operate at its programmed
frequency.
The Synthesizer Lock status is displayed in the power-up self-test results of
the Apex & ApexPro Tx Config program for programming the transmitter.
During normal operation, a ROM test is executed continuously. If an error is detected,
the transmitter resets itself.
