DME24N/DME64N
TEST PROGRAM
1. Test Program
1-0. Test Program Overview
This test program is used for “Total Test” of DME64N/
DME24N/ICP1.
Also, selecting “MY16C” from Test Category Selection
List allows the test of MY16-C. See the service manual
of MY16-C for details of the MY16-C test.
Because panels (key, encoder, LED, and LCD) cannot
be automatically tested and determined the failure, it
should be determined by visual inspection.
In the register writing test for FPGA or the like, error
check cannot be made to the register that cannot be
read. In this case, check it with external measuring
instruments (such as an oscilloscope and a logic
analyzer).
