PERFORMANCE TEST
2.1 Acceptance Test/2.2 Self Dignostic Test
Chapter 2 Testing
This chapter describes the following tests.
2.1 Acceptance test
2.2 Self Diagnostic test
2.3 Performance test
2.1 Acceptance Test
This section describes the procedure to perform the acceptance test.
1 Read the preface, to the user’s manual, “Checking the Package Contents” and verify
that you have all of the contents.
2 Make sure to understand the operating procedures as described in the user’s
manual.
3 Check each function using the user’s manual.

2.2 Self Diagnostic Test
The DX is provided with complete self diagnostic functions to enhance reliability in
measurement and serviceability.
When you turn ON the power, the DX will automatically execute the following types of
diagnoses alternately and display the results. After these tests are completed, the DX is
ready for use.
1 Main ROM sum test
2 Main RAM write/read test
3 A/D and A/D ROM sum test
4 Acquisition memory test
Table 2 shows the order and results of the self diagnostic tests.
