4、 Basic functions of intelligent communication fat scale module
1. Weight parameters
1) Weighing unit: Kg
2) Maximum weight: 152.0 Kg
3) Lifting weight (minimum displayed weight, zero tracking range): 5.0 Kg ± 0.1 Kg
4) Zero range: 6.0 Kg
2. System functions
1) E2PROM (24LC02) detection: Check for 2402 when starting up. If there is no such parameter, the E2PROM error screen "ErrE" will be displayed;
2) Calibration detection: detects whether it has entered calibration mode, usually used before leaving the factory;
3) Low voltage detection during startup: When the voltage drops to 2.4V ± 0.2V, a low voltage symbol is displayed;
4) Display weight limit: Display maximum weight limit=maximum limit+10g, if overloaded, display overload screen "O-Ld";
5) If the weight is below 0, it will display "----";
6) When there is no button operation and the weight has not changed for a certain period of time, it will automatically enter sleep mode.
3. Key operation
1) On/Off button: Power on/off switch
When the system is in the shutdown state, press this button to display the LCD fully. After 3 seconds, it will enter the weighing mode and display the preferred unit "Kg" and weight "0.000"; Press this button to shut down while in the power on state, and it will not work when calibrating.
2) Unit key: Conversion of weight units
Each time this key is pressed, the weight units will cycle through the conversion process in the following order: Kg ->Lb ->oz ->Kg.
3) Calibration key (CAL): Enter calibration mode
Long press the On/Off key while quickly pressing the Unit key 4 times in succession to enter calibration mode.
