WZX-I steering wheel parametric tester

WZX-I type to parametric tester Introduction I. Overview WZX-I type to parametric tester is Zibo Micro-Electronics Co., Ltd. independently developed high-performance microprocessor core road test instrumentation for automotive, tractor , construction machinery and other wheeled vehicles steering Performance Test. The instrument can measure the angle of the steering wheel is free, in-situ steering force, steering torque / steering force, angle, and other static and dynamic parameters and with the RS232 interface with computers and other detection equipment constitutes a flexible, intelligent detection system together. Instruments whole circuit design using a microprocessor as the test data processing unit, high-brightness LED display as the test data, test data have precise, intuitive display, stable performance characteristics; and an optional wireless transmission module can be easily and Other computer wireless data communication; instrument looks, easy to use; the test results can be displayed directly from the display output can be sent to the RS232 interface to computer processing output from the host computer, the whole process of connecting flexible and easy to operate by. The tester automatically stored and maximum angle of torque in this test procedure and its time corresponding corner and torque values ??in the test. The user can also be stored in real time during the test current test values ??(after the shutdown, the data is still there, unless boot, press the "Clear" key, the data cleared). The instrument's digital display, with fifteen brightness can be adjusted via software. Instrument displays both torque (Nm), can also be switched to display force value (N). The instrument complies with GB7258 "the safe operation of motor vehicles technical conditions" requirements. Second, the main technical parameters 1, the internal power supply: DC 8.4V (Section 2 # NiCad battery 7). 2, measuring range: steering wheel torque:. ≤100 Newton meters. Steering wheel turning force: ≤1000 Newton steering angle: ≤1080 degrees. 3. Resolution: steering wheel torque: 0.1Nm wheel angle 1 ° (serial output resolution of 0. 1 °) 4, Accuracy: steering wheel torque / force: <2%. Steering angle: ± 1%. 5, the standard 9-pin RS232 interface. (3 feet signal output, 2 feet signal input, 5 feet signals, baud rate 9600, 8 data bits, 1 stop bit, no parity).
