1、GM DAEWOO Auto & Technology EDS Engineering, GM DAEWOO Auto & Technology Standards TRANSIENT ANALYSIS TEST (EMC-41) Do Not Use on New Programs. Being Replaced by GMW3091 EDS-T-5009 ISSUED DATE: 1993. 08. 10 REVISED DATE: 2008. 11. 04 VERSION: 3 (Superceded) EDS-T-5009TRANSIENT ANALYSIS TEST (EMC-41)

2、 PAGE: 1/6 ISSUED DATE: 1993. 08. 10 REVISED DATE: 2008. 11. 04 VERSION: 3 GM DAEWOO Auto & Technology Note: This standard may be applied only for current project (incl. Variant Program). It is Superceded for all future projects and replaced by GMW3091. 1. PURPOSE Transient analysis test is to pick

3、up and analyze transient that is produced by electrical loads of the vehicle. This test is conducted at a time of evaluation or failure of electric components or for inspection and diagnosis of peculiar electric problems. 2. TEST EQUIPMENT 2.1. Transient digitizer 2.2.

The type of the test (evaluation, inspection, repair of trouble, certification) is specified by the tester and determines or affects the test point matrix. (See Attachment 1) 3.2. The test point matrix repres

5、ents the accessory, test point pin number, voltage current waveform, test equipment, etc. 3.3. Transient is produced by operating electric components of the vehicle. 3.4. Current/voltage transient is monitored at the specified test points in the system, subsystem and components (always at connector)

6、. If transient meets the pre-determined standards, it is the largest among the groups stored by the controller during test and may be raised up to 70. 3.5. Upon completion of transient analysis, hard copies are created by the controller that represent necessary items of each transient waveform. 3.6.

7、 Tabular summary stored in each floppy disk is created by the controller. Transient is obtained from the test vehicle while the vehicle is in the following operating modes: EDS-T-5009TRANSIENT ANALYSIS TEST (EMC-41) PAGE: 2/6 ISSUED DATE: 1993. 08. 10 REVISED DATE: 2008. 11. 04 VERSION: 3 GM DAEWOO
