The user manual should be enhanced by examples. Review: Funciona - EL sensor, versión modbus, funciona perfectamente, aunque al principio fue un poco difícil, puesto que la documentación inicial y el código de ejemplo no acababa de funcionar del todo bien. AL ponerme en contacto con el soporte técnico, el mismo día lo tuve resuelto, con una información más correcta y un código de ejemplo ejecutable perfectamente. Si no se conoce cóomo funciona el protocolo Modbus puede resultar dificultoso entender cómo operar con él. ## Features - 【 High Performance 】Rock-solid data output: 3-axis magnetic field, built-in Magli2c 13156 sensor + 13101 sensor + 13104 sensor + 13104 sensor - 【 Robust Design 】 Magnetic field measurement range: ±800uT, Low power consumption, fully compliant with RoHS standards - 【 Low-noise Level】 15 nT@200 cycle count, High-resolution: 13 nT@200 cycle count - 【 WITMOTION Advantage 】8-year Professional Attitude Measuring Solution Provider, sensors integrated R&D dynamic fusion algorithm and Kalman Filtering ensuring stable data output and excellent bias stability, low noise level, increasing measurement accuracy - 【 Worry-free Support 】12-month warranty, lifetime friendly customer service by WitMotion team.
