1、 Function
1. Working voltage: DC: 3.0V
2. Working current: ≤ 1000uA (excluding current for spotlights and backlights)
3. Static current: ≤ 5uA
4. Power on display mode: three and a half digits 1.8.8.8 or three digits 8.8.8
5. Measurement range: 3-150PSI; (Can be set)
6. Measurement accuracy: 1% FS
7. Resolution: 0.5psi or 0.1psi (optional)
8. When the pressure is zero, display: 0.0PSI or 00.0PSI; 0 kpa or 000kpa
9. Working temperature: -10 to 50 degrees Celsius
10. Pressure units: PSI, BAR, KPA2, KG/CM2 (optional)
11. Unit saving: The unit can be saved when turned off, but not when powered on. The default unit can be set (without 24C02)
12. Peak Lock: Reset to zero 10 seconds after displaying pressure value (reset time optional)
13. Alarm function: Display "ERR" when the maximum pressure is exceeded, with the option to flash or not flash
14. Low battery prompt: Battery voltage<2.5 ± 0.15V, low battery symbol flashing or LO
15. Shutdown time: 20 seconds shutdown (optional)
16. Backlight time: 20 seconds off (optional button switch or backlight time). When the pressure returns to zero and then refills, if the backlight goes out, you can choose to turn it back on again
17. Spotlight function: Spotlight time is optional and can be switched on and off through buttons.
18. Key functions: Confirm key (for unit switching, power on/off, press and hold for 3 seconds to enter the predicted value, only one option can be selected for both shutdown and predicted value functions), UP and DOWN keys (for adding or subtracting predicted values, press and hold for 3 seconds to enter the predicted value)
19. Predicted pressure: 3~100 PSI cycle (adjustable range) with steps of 1.0 PSI or 0.5 PSI
20. Buzzer (optional): It will sound once before or after the full display is turned on, with a button sound. If it is less than the predicted value, it will sound 3Bi, and if it is greater than the predicted value, it will sound Bi (or if it is within ± 1PSI range, it will sound 1Bi, and if it is not within the range, it will flash 3 Bi). The LCD can also flash an alarm at the same time.
21. Reset function: You can choose to press the reset button to reset (shared with the UP button)
