Terminal: RAM TEST
Use this command to test the RAM module to make sure each location can be read from and
written to. This test is a non-destructive memory test that tests memory word storage and
address lines. If problems are detected in the single pass mode, the test is stopped.
1 On the diagnostic Main Menu, select RAM TEST.
The RAM Test Menu appears.
RAM TEST (non-destructive)
1. SINGLE PASS
2. CONTINUOUS PASSES
3. STOP/START
4. RESTART
5. QUIT TO MAIN MENU
Test Count: 000005 Fail: 000000
2 Select the required option.
• Single Pass executes one pass through the test and stops. The Fail indicator is incremented
by one and the expected and read codes contain values. If the Stop/Start option is selected,
the status line indicates the system is stopped. Pressing Stop/Start again displays the
previous final test status and starts the test from the next memory location.
• Continuous Passes continually runs successive test passes until one of the other options is
selected. The Test Count/Fail display is updated after a successful pass. When the Stop/
Start selection is pressed in continuous pass mode, Stop/Start completes the test that is
currently running or restarts testing when pressed again.
• Restart test option re-initializes the Test Count/Fail display, then executes the last
selected test option.
Terminal: ROM TEST

reading each byte stored in the programs memory while generating a checksum. It compares
this checksum with the checksum stored in the last two bytes of the program memory.

The ROM Test Menu appears.
