Airflow Test (1) Airflow Range: (0.0625～310)g/s (standard conditions)
(2) Airflow Accuracy: ±0.5%Measurement of Throttle Body Outlet Pressure The measurement of throttle body outlet pressure is performed using a precision vacuum gauge with a range and accuracy of (-0.1～0) MPa and ±0.25%, respectively. Measurement of Throttle Plate Opening The opening is measured using a photoelectric encoder. Measurement range of the photoelectric encoder: (0～110)° Resolution: 5000 P/r TPS Power Supply DC power supply for TPS: (5±0.05) VDC 1A Active Electronic Throttle Plate Drive Parameters Control signal frequency setting range: 100Hz～2000Hz
Control signal duty cycle setting range: 2%～100%
Duty cycle control accuracy: 0.2%Power Supply for Electronic Throttle Body Throttle Plate Drive Motor Voltage/Current Range: (0～30)V/(0～10)ADC
Resolution of voltage/current set value: 10mV/10mA
Resolution of voltage/current displayed value: 10mV/10mA
