Hall EffectCoulometer
This Hall Effect Coulometer can measure all kinds ofbattery percentage of residual electric quantity.It could display “Percentageof residual electric quantity”“Charging capacity”“Discharge capacity”“current”“voltage”.The power supply voltage range isDC5～120V.It can be very convenient for power supply,youcan connect directly to the battery for supply and measure.Hall EffectCoulometer of WLS-DVA050 and WLS-DVA100 are produced by WOOLIIS TECHNOLOGYCO.,LIMITED.
1.Connection description
（1）The red power line is connected to thepositive electrode of the battery,the black power line is connected to thenegative electrode of the battery.（Note:Supplyvoltage can not exceed 120V ）.
（2）The electric wire by pass it through thehole of hall current sensor to measurepassing current.Make the triangle mark on the sensor point to the direction ofcharging current。When the sensor is installedcorrectly, the positive current is displayed when the battery is charging, andthe negative current is displayed when the battery is discharging.If not, thenyou put the direction of the sensor to do the opposite, you just have to turnthe sensor on the other side.
2.Display instructions
3.Button instructions
Buttonaccording to the length of time,there have three kinds of functions:
【1】Short press：Press the button time: T<1S.It is used to switch the display mode。
【2】Long press：Press the button time: 1S<T<4S. It is used to: clearcurrent/clear accumulation capacity/fill percentage of residual energy to 100%or clear to 0%.
【3】Super long press：Press the button time: T>4S。It is used toenter setup menu.
4.Display mode switching method
Instandby state, short press the button, you can switch for difference displaymode.
【1】Short press the button, the screen will display “A”two seconds.Indicatesnow is the current display mode.The right of the LED will display the currentunit “A”when in the current display mode。The currentunit of“A” does not blink when the positive current is displayed, and thenegative current is constantly flashing.
Inthe current display mode, the long press of button will be cleared the current.(Note: It must be at zero current when cleared).
【2】Short press the button again, the screen will display “AH” two seconds.Indicatesnow is the display mode of the cumulative capacity of the forward current.Whendisplay the positive capacity the right of the LED will show “C”,and this"C" won't blink.(Note: the unit of the capacity value is AH).
Whenthe positive capacity value is displayed ,the long press of button can be clearcumulative positive capacity.
【3】Short press the button again, the screen will display “- AH” two seconds.Indicatesnow is the display mode of the cumulative capacity of the negative current.Whendisplay the negative capacity the right of the LED will show “C”,and this"C" will keep flashing.(Note: The unit of the capacity value is AH).
Whenthe negative capacity value is displayed ,the long press of button can be clearcumulative negative capacity.
【4】Short press the button again, the screen will display “PC” two seconds.Indicatesnow is the display mode of the percentage of residual electric quantity.Whendisplay percentage of residual electric quantity the right of the LED will show“?”.It will horse race lam when the charging current ismore than 0.5A .
Whenthe percentage of residual electric quantity is displayed ,the long press ofbutton will be clear percentage of residual electric quantity to 0% or fill itfor 100%.
【5】Short press the button again, the screen will display “A PC” two seconds.Indicatesnow it is rotation display mode,it will rotation display the percentage ofresidual electric quantity and current .The cycle is three seconds.
5.Thebattery rated capacity value setting method and the battery percentageautomatically fill voltage value setting method
Instandby state, super long press the button(Note:more than fourseconds) then after release the button you will entering the set menu.Inthis menu you could short press button to switch “1-C”or “2-U”.Its function isto set the battery rated capacity of“1-C”.Its function is to set automatic fill power voltage of“2-U”.And long press button your willenter the function menu of your select.
【1】Enter“1-C”the battery rated capacity settings menu，LEDwill blink display of “XX.XC”.And then press the button the value will alwaysincrease.Then Release the button, press the button again the value will alwaysdecrease.Until set to the value of you need.When don't press the button withinfive seconds, the screen will stop flashing and save the rated capacity data.
【2】Enter“2-U”the battery percentage automatically fill voltage value settingsmenu，LED will blink display of “XX.XU”.And then pressthe button the value will always increase.Then Release the button, press thebutton again the value will always decrease.Until set to the value of youneed.When don't press the button within five seconds, the screen will stopflashing and save the voltage value data.Suggest this voltage value is set tothe highest voltage value when the battery is charged with full power.When thisvoltage was set up, after a full charge, the remaining battery power willautomatically fill percentage was 100%.This function can be removed from theuser to manually fill the battery percentage for 100%.
Why is itnecessary to have automatic fill? Because of the charge and discharge ofconsumption does not equal, so the cycle charge discharge after a few times ofthe remaining battery power percentage is not accurate, so it is necessary toautomatically fill function.
