电气参数：
电源：两节AAA电池供电，间断使用可持续超过三个月
工作电压：2.4V～3.5V
工作电流：<=5mA
关机电流：<=2uA
操作说明：
开/关机：将电子秤放在水平的地方，按“ /T”键开机，此时显示“8888”检测零点，待稳定后显示零重量即可进行重量秤量。如果再长按 “ /T”键并保持2秒钟则关机。若无重量称量且无任何按键操作120秒状态，电子秤会自动关机；
单位转换：在正常秤量中，按“UNIT”键可以进行“千克(kg)→盎司(oz)→磅(lb)”之间的重量转换，1千克=35盎司=2.2磅；
去皮：当使用容器装散装物品称重时，可先将容器置于秤上，短按“ /T”键，待重量窗显示零后再装入物品称重，就可得到物品的净重值；
校准：当感觉产品秤量重量不准时，可以自己重新校准。首先要先准备要标定量程的砝码，先将电子秤关机，按“ /T”键开机瞬间立即按下“UNIT”键并松手，进入标定状态后，按“UNIT”可以按照“7000g”->“5000g”->“3000.0g”->“1000.0g”的顺序选择不同标定量程，确定后按“ /T”键进入显示内码，称盘要保持空，待到内码平稳后再按下“ /T”键，显示“CAL0”->“标定量程”->“内码”表示标定零点完成，然后将标定砝码放到称盘上面，待内码数值平稳后再按下“ /T”键，显示“CAL1”->“PASS”后自动关机表示标定成功。
注意事项：
1.秤量大于额定重量的105％会显示“O－Ld”超载，此时应立即取下物品并减轻物品重量再进行称量，持续加重会造成产品不可恢复性的损坏；
2.开机显示“LO”，表示电池电量不足，应及时更换电池；
3.如果产品长时间不使用则应取出电池，避免因电池漏液导致产品损坏。
WH-B Series Portable Electronic Scale User’s Manual
Description
WH-B series electronic kitchen scale is a new production made by WeiHeng Electronic Scale Ltd. with high precision.Used in family kitchen food weighing, common Traditional Chinese Medicine weighing, etc. With the characters of fine shape, high precision, multi-unit conversion, fast response, stable weighing, etc.
Range/Precision
7kg/1g, 5kg/1g, 3kg/0.5g, 1kg/0.1g
Electronic Characters
Power: 2 AAA batteries, over 3 months in intermittent used.
Working Voltage: 2.4V – 3.5V
Working Current: <=5mA
Power Off Current: <=2uA
Instruction
Power On/Off: Put the Scale in a vertical position and press “/T”, it would power on that display “8888” and catch zero weight, you should keep stable and don’t weight until display zero weight. If press “/T” and hold 2 seconds in working state it will power off , or do not any operate in 120 seconds it will power off automatic as well.
Unit Convert: In working state, press “UNIT” could convert the unit of “kilogram(kg)-> ounce(oz)->pound(lb)”, 1 kilogram=35 ounces =2.2 pounds.
Tare: In working state, press “/T” would remove the tare, display zero weight, press “/T” again would add to the tare.
Calibrate: If the scale inaccurate, you may calibrate it. You need a weight which in calibrate range. Then shut down the scale, and press “UNIT” the moment of power on, enter the calibrate state. You can choose a calibrate range of “ 7000g”->”5000g”->”3000.0g”->”1000.0g” by press “UNIT”. Press “ /T” enter calibrating, keep scale plate empty and press “ /T” to calibrate zero point, it would display “CAL0”->”range”, then put the weight on the scale plate and press “ /T”, it would display “CAL1”->”PASS” indicate calibrate successfully.
Caution
1. When the scale goods over rated range’s 105% it would overlord and display “O_Ld”, you should remove the goods and reduce the weight when weigh it again, increase the weight would damage the scale.
3. Display “Lo” when power on indicate low power, you should replace battery.
4. You should remove the battery from scale when do not used in a long time, or the battery would leakage.
