DIAGNOSE/Memory
2NDMNU:../DIAGNOSE/Memory
Testing memory: ROM
>>>>>
Description:
There are two types of memory to test:
•
ROM
•
RAM
When the test is running, this will be indicated by a number of arrow on the right side of the display. When a total of
five arrows are displayed, the test is finished. If no errors have been found, a message OK will appear on the display
to indicate that the test has been completed; otherwise the message FAIL will appear. When the ROM has been
tested the check sum is also displayed.
To continue testing on the next main section, press the E button. To cancel further testing, press the
button.
When both memory types have been tested, a message stating the result of the complete test will appear.
The RAM check is done by writing and reading the sequence Ox55 and OxAA to/from each memory position in the
RAM. Since this operation involves moving the content out of the RAM, there is a potential risk of losing that data if
the apparatus is switched off during the test. A built-in safety procedure will detect such an error during power-up and
will report a general failure in the RAM. If this happens, a factory reset will be performed.
To perform the main test once more, press the E button. To return to the previous menu level, press the
button.
DIAGNOSE/Configuration
The Diagnose Configuration displays the units detected during power up. The identification may include type number
(PT5300), Serial Number (KUxxxxxx), and when available the software version.
