FM4/FM5 IPSRSYS - 6 UCB, May 5, 2006 Performance Tests Instrument Suites have gone through numerous CPTs/LPTs. Over 80 CPTs/LPTs have been completed on all units. THM-SYS-PROC-005 Instrument CPTs (2-3 per Suite): Initial Run at Instrument Suite Level, Pre-Environmental, Post-Environmental Runs on Probe THM-SYS-PROC-006 Instrument LPTs (over 15 per Suite): Pre-TV, 2 Cycles every Hot/Cold ESA/IDPU TV, 6 Cycles every Hot/Cold Suite TV, Post-TV CPTs/LPTs are also performed as necessary pre- and post- workmanship vibes, thermal re-tests, rework, etc. Performance Tests on F2 Probe CPT/LPT procedures have been successfully run through ITOS on the Probe Procedures and ITOS data base have been reviewed for conversions, limits and logic Performance Tests
