About VAMKHA Legal Scale Checker
Streamline Weighing Instrument Compliance and Verification
The Scale Verification & OIML Compliance Tool is a high-utility utility designed for metrologists, scale manufacturers, service technicians, and quality control inspectors. It eliminates manual math mistakes by instantly evaluating compliance boundaries for weighing instruments according to international legal standards (OIML R76).
🎯 KEY FEATURES
• Term-Accurate Metrics: Designed specifically to track Scale Divisions (n), Maximum Capacity (Max), and Verification Scale Interval (e).
• Smart Parameter Solver: Input any two known values (Max, e, or n), and the tool instantly computes the missing third value.
• Auto-Formatting Inputs: Built-in usability tools scale integer inputs seamlessly to legal fractional values (e.g., automatically shifting "5" to "0.005 kg" on blur) to save time and reduce typing errors.
• Dynamic Multi-Unit Conversion: Swap natively between mg, g, and kg. The calculator auto-adjusts stored values instantly without losing calculation integrity.
• Instant OIML Evaluation: Automatically assesses and flags your values against legal minimum and maximum division restrictions for Accuracy Classes I, II, and III.
• Maximum Permissible Error (MPE) Tables: Generates complete dynamic step tables showing statutory limits and uncertainty boundaries (±0.5e, ±1.0e, ±1.5e) optimized for your specific configuration.
⚖️ COMPLIANCE TRACKING
• Class I: Enforces ultra-precise limits (50,000 min divisions to Infinity max).
• Class II: Dynamically shifts limits based on intervals (supports 100 to 100,000 max division ranges).
• Class III: Standard commercial scale validation tracking.
🔒 PRIVACY & SAFETY ASSURANCE
• 100% Client-Side Execution: Your data never leaves your device. All mathematical calculations happen locally within the extension environment.
• No Remote Scripts: Built purely with secure local scripts to ensure strict adherence to Google's Extension manifest safety requirements.
• Zero Tracking / Zero Telemetry: We do not collect, store, or transmit your device metrics or calculation histories.
