Performance Parameters of Body Scale Scheme
Startup mode: automatic weighing and startup, weighing 5.0kg+0.1kg.
Unit and display graduation: support two units kg and Ib, and the corresponding graduation 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 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, namely 50kg, 100kg and 150kg.
Low power prompt: When the battery voltage is lower than 2.4+0.1V, the LCD displays "Lo", and it will automatically standby after 4 seconds.
Overload prompt: When the weighing value is greater than 183.0kg, the LCD will display "oL".
Automatic standby time:
After locking weight: 10+1S;
Unstable shutdown: 20+1S;
After starting up and returning to zero: 10+1S;
Reset to zero: reset to zero after the full display is stable; In weighing state, the weight is less than 3kg and automatically returns to zero when it is stable;
Temperature and humidity characteristics: chip operating temperature is - 40 ° C~85 ° C Relative humidity: ≤ 90%.
Working voltage: 2.4V~3.6V power supply
Memory range: 3 groups of memory values, memory range is 0.3+-0.1kg
Backlight: the backlight is on when the machine is turned on or weighing is on, and the backlight is off when the weighing is stable or there is no operation for 10s
