Tobacco stem function testing machine
Product Introduction:
1.Conduct semi-automated testing, with manual loading of materials. Automatic switching should be achieved between test items. The test results should be automatically judged, and the test output should be automatically counted and the yield rate displayed. Eight products should be tested each time.
2: The test output and input need to be optimized to a copper column compression contact test.
| Item | Specifications |
|---|---|
| Sensitivity Test | 1. Connect a voltmeter between D+ and D-. Trigger the microphone at an airflow rate of 12 ml/s and observe the voltage change on D+.2. The voltage on D+ varies between 2.45–2.65 V. |
| Draw Resistance Test | 1. Connect an atomizer (simulated) and test draw resistance at an airflow rate of 14 ml/s.2. Draw resistance of 0.8–1.1 kPa is acceptable. |
| Protection Test - Overcurrent Short Circuit | 1. Apply a 0.2 Ω load between D+ and D-, blow air toward the microphone and observe the LED status.2. The red LED flashes 3 times when blowing air. |
| Flow Rate | 30 ml/sec, Accuracy: ±0.1 ml/sec |
| True RMS Voltage | 10 V, Accuracy: ±0.01 V |
| Resistance | 1/0.2 Ω, Accuracy: ±2% |
| Draw Resistance Range | 5000 Pa, Accuracy: ±6 Pa |
