4 - 10
In addition to diagnostic tests 1-6, the MLP–Trim automatically performs two power up
diagnostic routines during every Power Up.
RAM TEST - Random Access Memory
The MLP–Trim performs a pattern read/write test on RAM.
If RAM fails, “---5” Is displayed. The test will stop if a failure is
detected. Press “Clear ” to exit the test.
IF the RAM is good, the MLP–Trim will begin the PROM test.
PROM TEST
The MLP–Trim performs a checksum comparison on the PROM.
If the test fails, “---3” is displayed. The test stops if a failure is
detected. Press “Clear” to exit the test.
If the PROM is good, exit is automatic. The MLP–Trim will begin the
initialization routines and normal operation.
