Communication Protocol: Body Fat Scale Cloud Protocol. Lipid measurement: Bia Analysis. SUPPORT APP: core OKOK international version, domestic version. System Support: Android 4.3, ios 7.0 + . Bluetooth Support: Bluetooth 4.0 + . Connection tip: LCD Screen Flashing Display“Bluetooth Logo” connection, the connection successfully shows Bluetooth logo. 2、Main performance indicators 2.1 BOOT mode Start up the scale, the boot weight is 5.0kg 0.5kg. Press the unit key to boot. 2.2 Unit and display Three KG/LB/ST units are supported, with a default of KG. 2.3 Scale 0.1kg/0.2LB/ST:1LB。 2.4 Weighing range 1.0kg～183.0kg。 2.5 Voltage range EB8204：2.4V-3.0V。 2.6 Operating Current The operating current (18mA at 3.0 v) and the average standby current ≤10uA (actual minimum 5.2UA) . 2.7 Calibration The three-point calibration is 50kg, 100kg and 150kg respectively. 2.8 Overload indication When the weight is greater than 183.0 kg, the LCD will display“Err”, indicating the user's current weight overload (not calibrated, no overload function) . 2.9 Automatic shutdown time BOOT BACK TO ZERO: 10 seconds; EB8204 Instruction manual 第 3 页 共 6 页 2018-06-09 After Weight Lock: 10 Seconds; UNSTABLE SHUTDOWN: 15 seconds; Weight Hold: 10 seconds. 2.10 Return to zero Power-on full display after automatic return to zero (no range limit) ; Weighing status, the detection of weight ≤3kg, 1.0 kg and stable flicker 3 times after the display“C” 2 seconds to zero;； Standby status, regular chase zero every 4 hours for a return to zero processing: Timing catch zero conditions: With the same boot low-frequency AD acquisition, weight range in +/-0.5 kg, beyond the non-return to zero, AD to stability. Timing Zero Requirements: Can Not turn on Bluetooth, can not turn on display, can not turn on backlight, in the chase zero period, press the unit key can be normal boot, in 3 seconds if unconditional return to zero, enter the low-power shutdown state, starting from now on, the next 4 hours are timed by repeating the cycle. Each cycle is timed from automatic shutdown to boot. 2.11 Temperature and humidity characteristics Operating temperature: 0 ° C ~ 40 ° C. Relative humidity: ≤90% . 2.12 Back Light White backlight with black lettering on blue background. 3. Power supply EB8204：3.0 v Battery Powered (2 * Aaa Battery) . 4. weighing step 4.1 Power on, please put the scale on the level of hard plane for zero, zero time about 3 seconds, zero can be completed after the weighing, if the power has been unstable, LCD display. 4.2 In standby or on-line state, people can directly stand on the scale for weighing. 4.3 When the weight value is more than 3.0 kg and stabilized, the weight value flickers 3 times, and shows the stable weight all the time. If the weight is less than 3 kg, then zero treatment, and less than 3 kg and more than 1 kg, then zero treatment, then show: “C” shows zero in 2 seconds. However, when the weight is zero, the weight is negative need to chase zero processing (the greater the negative value is expressed as a smaller) display chase zero should not be prompted. EB8204 Instruction manual 第 4 页 共 6 页 2018-06-09 Notes: After zero, when the weight is locked under the scale to lift the scale, at this time for negative weight, you can chase zero processing, but can not unlock the locked weight, put down the scale can not unlock the lock. Only when weighing the weight to determine the stability will track zero tips, such as: On the scale to lock the weight, found on the next scale & Lt; 3.0 kg or found that the weight of the Negative Show Zero Weight; direct Weighing & Lt; 3.0kg •1.0kg • weight locked after zero-tracking • FLASH AFTER TREATMENT: “C”. When displayed as 0 Weight, lift the Scale & Lt; 3.0k (including negative weight) shows can chase zero, chase zero directly after the show zero weight, do not display: “C”. 4.4 Weight stability, the cumulative weight of more than 5kg re-weighing, unlock the weight of the lock. 4.5 BOOT more than 10s without on-scale action or weight stability more than 10s without under-scale action, into standby mode. 4.6 When the weighing value overload, LCD display“Err”, after the weighing value back to the normal range, LCD display normal weighing value. 4.7 The memory range above 10kg is 0.3 kg (more than 0.3 kg updated display) , no memory power. 4.8 Display“C” status: Weight & Lt; 3kg, $1kg, display“C” after zero. 5. Calibration procedure 5.1 Access calibration method: 5.1.1 First calibration, weighing the state, placed 100kg weight on the scale after the stable into the calibration; 5.1.2 Non-first calibration, power-on (that is, the first battery installed) , weighing state, put more than 100 kg weight onto the scale plate, stable and then placed 50 kg, into the calibration;. 5.1.3 Press the unit key is“Three short one long” into the calibration; 5.1.4 Short-connect calibration jumper into the calibration (PCB need to do a pair of pads, for tweezers touch) ; 5.2 Lift all the weights on the scale, the weight back to zero and stable 0.75 seconds, LCD display“50.0kg”; 5.3 Put 50kg weight onto the scale plate, to weig…
