Electronic Digital Pressure Switch Upper Limit Alarm For Air Pump CE / CCC Certification
Digital pressure switch, also known as smart pressure switch, is an intelligent, high-precision pressure control device that integrates pressure measurement, display, and control.
The main functions of digital pressure gauges are simple operation, low price, anti-vibration, high control accuracy, and long service life.
The pressure switch has a delay control function, three display units can be arbitrarily switched, the error of a key to clear and other functions.
1.(ON/OFF) Run key: System run key, the parameter must be set to close the run key, otherwise the setting cannot be performed.
2. (SET) setting key: short press this key to enter the pressure upper and lower limit setting state, press and hold for 3 seconds to enter the system setting state.
3. Increase the key (▲): Press the key once to increase the number by 0.01MP. Press and hold for 2 seconds to increase the number by 0.1MPa.
4. Decrease the key (▼): Press the key once to decrease the value by 0.01MP. Press and hold for 2 seconds to decrease the value by 0.1MPa.
