Automobile instrument

Instrument technical parameters

• ambient temperature

• operating temperature: - 40 ℃ ~ 75 ℃ (except TFT screen)

• LCD temperature: - 30 ℃ ~ 75 ℃

• storage temperature: - 40 ℃ ~ 90 ℃ (- 40 ℃ for 48 hours, 85 ℃ for 48 hours, 90 ℃ for 1 hour)

• voltage

• normal working voltage: 9V ~ 16V (when the voltage is outside this range, it will not be taken as a concern)

• network communication voltage: 6.5V ~ 18V

• test voltage: 13.5V

• nominal voltage: 12V

• can network working voltage: 6.5V ~ 18V

• ground wire drift: at the non analog input terminal, the ground wire drift is less than 0.5V

• minimum effective voltage of high level signal: 9V

• maximum effective voltage of low level signal: 1V

• power off hold time (EEPROM stored data): 4S

• quiescent current

• dark current: < 1mA (test voltage 13.5V, ambient temperature 25 ℃± 5 ℃)

• sleep wake up

• only can network and ign on can wake up the instrument. When these two wake-up conditions do not exist, the instrument will remain in sleep state (power saving mode)
