Functional parameters of the weight scale scheme:
Power on mode: Automatic weighing and power on, with a weight of 5.0kg+0.1kg.
Unit and Display Scale: Supports two units, kg and Ib, with corresponding scale values of 0.1kg and 0.2lb,
Turn the switch to change the unit.
Weighing range: 3.0kg~183.0kg
Voltage and current: During normal operation, the sensor is supplied with a voltage of 2.3V, a working current of 6mA, a standby current of 1uA, and a scanning current of 200uA.
Calibration: Three point calibration, namely 50kg, 100kg, and 150kg.
Low battery prompt: When the battery voltage is below 2.4+0.1V, the LCD displays "Lo" and automatically enters standby mode after 4 seconds.
Overload prompt: When the weighing value is greater than 183.0kg, the LCD will display "oL".
Automatic standby time:
After locking the weight: 10+1s;
Unstable shutdown: 20+1s;
After turning on and resetting to zero: 10+1 seconds;
weight scale solution
Zeroing: Reset to zero after the full display stabilizes upon startup; Weighing status, the weight is less than 3kg and automatically returns to zero after stabilizing;
Temperature and humidity characteristics: The working temperature of the chip is -40 ° C~85 ° C, and the relative humidity is ≤ 90%.
Working voltage: 2.4V~3.6V power supply
Memory range: 3 sets of memory values, with a memory range of 0.3+-0.1kg
Backlight: The backlight lights up when the machine is turned on or weighed, and the backlight goes out after 10 seconds of stable weighing or no operation
