DROK DC 8-100V Coulombmeter 100A Parameter Voltage: 8-100V Current: 0.05-100A Capacity: 0.1-99999AH Power: 50KW Voltage Precision: ±1% + 2 digits Current Precision: ±0.5% + 2 digits Measure Speed: 20 Times per Second Display Board Size: 86*53*17mm/3.39*2.08*0.67in Measure Board Size: 56*36*34mm/2.20*1.42*1.34in Function 1.CLR: current clear function. When no-load current is not zero, enter this function, Short press ▲ to clear the no-load current. 2.BAT: set battery total capacity. 3.BPC: set available capacity percentage. 4.LED: set LCD screen backlight brightness. Level 0-10 can be adjusted 5.STE: set screen turn off time. when working time is longer than the set time, screen will auto turn off. 6.STI: set current value for turning off screen. When measure current is lower than the set value, screen will auto turn off. When measure current is higher than the set value, screen will auto turn on. 7.BKC: set the screen display colors, total 2 colors to choose, black-white and colorful. 8.LAG: set the language(English/Chinese). 9.LVP: Low voltage alarm. When voltage is lower than LVP value, the capacity will auto clear. 10.LBR: turn on/off backlight alarm. After turning on LBR, when the remain capacity is lower than 20% or voltage is lower than LVP, the backlight will flashing to alarm. When charging current is higher than STI, the backlight will also flash. 11.ADS: Communication Address. 12.PAI: the value of current clear. After no-load current clear, the shunt might make current higher than zero, which can set PAI. When current is lower than the set value, the current value will zero. 13.OVP: the voltage value of max capacity. When battery voltage is higher than OVP, the capacity will auto fill up.
