Mic Head Sensitivity Test Machine (Computer Version)

Description:

This machine uses a programmable power supply to simulate battery power supply, and a suction tube is drawn out through a piston pump to simulate manual suction for testing.

Advantage

1. Can test the static current, detect the power supply to the microphone head when the static current is not suction, accuracy of 0.1μA

2. Can test the load current, test the microphone head suction process after accessing the load current, accuracy of ± 8Pa

3. Can test the microphone head sensitivity, detection of the microphone head suction to the ability of the output voltage of the trigger when the negative pressure, accuracy of ± 8Pa

4. Test the microphone head voltage value when the work of the accuracy of ± 0.01v

5. Test the microphone head release pressure, when pressure falls off the pressure value 6. Test microphone head release pressure, when the pressure drops when the pressure value of the microphone head off

6. The test can be real-time monitoring of the output voltage of the microphone head, real-time suction, and generate real-time analysis curve, can also generate a cycle of testing the fatigue analysis of the microphone head sensitivity

curve

7. With the test data storage and export functions, and can be exported to generate Excel data tables or data analysis reports

8. With RS232, RS485 Communication function (optional)

9. Provide embedded intelligent PC monitoring system.
