What problem does it solve? Engineers maintaining the HT9045 test handler often struggle to trace how Contact Force is computed across cContact.cpp and ContactForce.cpp, including Min/Max Force limits, Compliance Unit factors, and EP pressure alarm conditions. This Skill consolidates that knowledge into a single reference so questions about force calculation, cylinder diameters, and alarm codes can be answered without reading 19,000 lines of source code. ## Core Features & Use Cases - Force Calculation Reference: Documents the full chain from ShowArmAndDeviceForce through CalculateTotalAirForce, GetMinForce, and GetMaxIndexForceLimit, including formulas for per-device force, D28 diameter-based limits, and SLK class defaults. - Configuration Lookup Tables: Provides quick-reference tables for Kit Diameter Min Force, Compliance Unit positions, Index Press Type limits, DutCount/HeadCount per TestMode, and D04/D27/D28 config switches. - EP Alarm Diagnostics: Explains WAR1605 EP pressure deviation checks, ADAM_Alarm_Kg tolerance tiers, proportional valve voltage alarms WAR16322/WAR16323, and EP Leakage compensation. - Use Case: When a customer reports that a 30mm kit cannot reach the expected force, use this Skill to determine that the D28 limit with EP_MAXKPA≤500 caps the force at roughly 9.01 kg per Compliance Unit. ## Quick Start Ask how the maximum contact force is calculated for a 40mm SLK cylinder on an 85 kg index press machine.
