|---|---|---|
| ອຸປະກອນບໍ່ເປີດ | ແບັດເຕີຣີຕາຍ ຫຼື ຕິດຕັ້ງບໍ່ຖືກຕ້ອງ | Check battery polarity or replace with a new 9V battery. |
| Inaccurate readings / Zero drift | Environmental factors or sensor drift | Perform one-button zero calibration by long pressing the HOLD button. Ensure ports are open to atmosphere during calibration. |
| Display shows "Err0" | Exceeds positive pressure range | The measured pressure is above the maximum positive range. Reduce pressure or use a device with a higher range. |
| Display shows "Err1" | Exceeds negative pressure range | The measured pressure is below the minimum negative range. Reduce vacuum or use a device with a wider negative range. |
| Backlight ບໍ່ເຮັດວຽກ | Backlight off or low battery | Press the °C/°F button to toggle backlight. Check battery level and replace if low. |
| Auto-shutdown occurs too quickly | Normal operation (15 minutes inactivity) | This is a power-saving feature. The device will shut down after 15 minutes of no operation. |
