Product Introduction:
Conduct semi-automated testing, with manual loading of materials. Automatic switching should be achieved between test items; automatic judgment.
The test results should automatically count the test output and display the yield rate. Eight products are tested each time.
The test output and input need to be optimized to a copper column compression contact test.
| Item Name | Specifications |
|---|---|
| Static Current | 1. Shutdown current < 15μA2. Connect 3.7V battery to B+ and B-, measure with microammeter in series; after 5s without pressing the power button and non-charging state, the value < 15μA. |
| Output Test - Atomizer & Working Status | 1. Atomizer detection and working status test2. Microphone detection |
| Output Test - LED & Voltage | 1. Connect 1Ω resistor between D+ and D-, observe LED status, then press the button to check output voltage.2. With 1Ω resistor connected, white LED turns on during smoking (fades in 2000ms at start, fades out 2000ms at stop, stays on during puff). |
| Output Test - Microphone Voltage | 1. Connect 1Ω resistor between D+ and D-, blow air toward the microphone and observe voltage change on D+.2. At airflow rate 14ml/s, voltage on D+ varies between 2.45–2.65V. |
| Protection Test | 1. Overcurrent short-circuit test2. Low-voltage test3. Over-puff protection |
| Overcurrent Short-Circuit Test | 1. Apply 0.2Ω load between D+ and D-, blow air toward microphone and observe LED indication.2. Red LED flashes 3 times. |
| Low-Voltage Test | 1. When input voltage < 3.0V, observe LED status.2. White LED flashes 10 times (200ms on / 200ms off), smoking prohibited. |
| Over-Puff Protection | 1. Continuous puff time: 5s ± 0.5s2. White LED flashes 3 cycles (200ms on / 200ms off), output disabled. |
| Charging Function Test | Charging test |
| Charging Test Details | 1. Connect 5V charger, observe LED status and ammeter reading.2. White LED breathing indicates charging; charging current < 670mA (18–45℃). |
