Tester: [ZHANG]
Objective: Evaluate the timekeeping accuracy of CALIN rail meters under different temperature conditions.
Preparation: Confirmed proper installation and functionality of three rail meters (A, B, C) in low (-20°C), high (60°C), and ambient (25°C) temperature environments. Standard clocks were set for comparison.
Results:
Mid-term inspection showed no significant deviation in time displayed on rail meters compared to standard clocks.
Final analysis revealed total time errors of ±0.1 seconds for rail meter A (low temperature), ±0.2 seconds for rail meter B (high temperature), and within ±0.02 seconds for rail meter C (room temperature).
Conclusion: CALIN's rail meters maintained high time accuracy under extreme temperature conditions, with outstanding performance at room temperature. This meets industry standards and surpasses similar products, demonstrating CALIN's excellent technical level in meter manufacturing.
