The weighing scale scheme has the functions of automatic weighing and starting, two unit kg, LB display, low power prompt, overload prompt, zeroing, etc. The accuracy measurement can be accurate to 0.1g, which will not miss the existence of every piece of meat on your body. When the scale scheme works normally, the power supply voltage of the sensor is 2.3V, the working current is 6mA, the standby current is 1uA, and the scanning current is 200uA; when the standby time is more than 1 minute, the power will be cut off automatically to reduce the battery loss.
1、 Weight scale scheme function parameters:
Starting mode: automatic weighing machine, weight is 5.0kg + 0.1kg.
Unit and display index: support two units kg and IB, and the corresponding index values are 0.1kg and 0.2lb,
Toggle the switch to change the unit.
Weighing range: 3.0kg ~ 183.0kg
Voltage and current: in normal operation, the power supply voltage of the sensor is 2.3V, the working current is 6mA, the standby current is 1uA, and the scanning current is 200uA.
Calibration: three point calibration, 50kg, 100kg and 150kg respectively.
Low power prompt: when the battery voltage is lower than 2.4 + 0.1V, LCD displays "Lo", and it will automatically stand by after 4 seconds.
Overload prompt: when the weighing value is greater than 183.0kg, the LCD will display "ol".
Auto standby time:
After locking the weight: 10 + 1s;
Unstable shutdown: 20 + 1s;
After turning on and returning to zero: 10 + 1s;
Return to zero: return to zero after the start-up full display is stable; in the weighing state, the weight is less than 3kg and returns to zero automatically after it is stable;
Temperature and humidity characteristics: the chip operating temperature is - 40 ° C ~ 85 ° C, relative humidity is ≤ 90%.
Working voltage: 2.4V ~ 3.6V power supply
Memory range: three groups of memory values, memory range is 0.3 + - 0.1kg
Backlight: power on or weighing backlight is on, weighing is stable or no operation 10s backlight is off
