Description It is used for measuring handrail belt, steps and pallets speed,start and brake acceleration,stopping distance ,as well as handrail belts and step/pedal speed synchronization rate of escalators and moving walks. It can also test the escalator/moving walks handrail belt deviation protection function and overspeed and anti-reversal protection function. Functions Measuring the speed of two handrail belts and steps/pallets at the same time. Test the speed deviation protection function of handrails of the escalator/moving walks. Test overspeed protection and anti-reversal protection function of escalator and moving walks. According to the speed data of the handrail belts of both sides and pallets of escalators/moving walks, 7-inch intelligent terminal automatically calculate the synchronization rate and speed deviation, braking deceleration, average speed, stopping distance, overspeed protection response time,Anti - reversal protection action response time etc. Wireless data transmission is adopted between the intelligent terminal and the main control box. Setting parameters on colour touch screen. automatically display test results, easy to operate. Two trigger mode selection Running direction correction function On-site Bluetooth printing function Parameters Speed range: 0.2-9.99 m/s (1-9999 rpm) Speed accuracy: 1% Speed resolution: 0.001m/s (1 rpm) Overspeed protection speed range: 0ï½?9.99m/s Unintentional reversal protection speed range: 0ï½?9.99m/s Display: 7 inch colour touch screen,Hand input.
