The OP2 tests the internal memory. The OP2 shows the operating status in
the upper display line „RAM-EPROM-FLASH-TEST".
The actual test step is displayed in the lower line. When errors occur, OP2
stays at that particular test step and issues the message „TEST ERROR". If
no errors are detected, OP2 returns to the self-test menu after the test has
been completed. The test takes approximately two minutes.
Message texts during testing:
WRITE READ TEST OF RAM
CALCULATE CHECK SUM OF EPROM
WRITE READ TEST OF FLASH
End of the self test and the OP2 returns to the SYSTEM mode.
