Taidacent 48V Lithium ion Battery Capacity Meter Lcd Voltage Tester Monitor Charge Indicator for Automotive Lead Acid Battery
★ TK15 is a kind of high precision current type battery capacity tester(also known ascoulometer)，which can test the voltage，current and capacity of battery to help users know the state of battery in time. TK15 has memory function. It is suitable for mobile and portable equipment、e-bike、balance car、cleaning machine、instrument、ups and so on.
★TK15 is suitable for lithium battery，lithium iron phosphate battery ， lead-acid battery and nickel-metal hydride battery which working voltage is from 8V to 100V.
Attention：The size and function of TK15 are the same, but the internal parameters are different, so it must match correct sampler, and cannot exchange.
Working interface description
１．First, series connect the sampler to the negative circuit of your battery. B- of sampler connects to B- of battery. P- of
sampler connects to P- of output or C- of charge.
2．Then take a wire of 0.3-0.75 mm².One end of the wire
connects to positive of battery，another end connects to B+ of sampler (any one is ok).
3．Finally connect sampler to TK15 by the shielded wire. Afterconfirm and power on, TK15 will be work normally.
★ Preset capacity and voltage setting：
1. Press the“ ”key for 3s in the main interface to enter
2. Press“ ”or“ ”key to select items;
CAP—preset capacity：an initial capacity has been set at
factory，please set it according to the real capacity of your
FULL V—full voltage：when the voltage is higher than it the
percentage will be 100%；
ZERO V—zero voltage： When the voltage is lower than it the
percentage will be 0%， and backlight off.
DRIFT—Current Zero Calibration: Current Zero Deviation
Connection diagram of 50A sampler
Attention：Please connect as shown strictly. The sampler
must be series connected to the negative circuit， it is forbidden
to connect to the positive circuit. If you want to extend the
shielded wire， you must use 4 lines of same specification.
Connect the load，when the discharge current is higher than backlight on current，backlight on (if backlight blinking， means B- and P- of sampler are inversely) indicate batter discharging. Besides，display discharge current and remaining discharge time. The time will fluctuate if the current fluctuate greatly.
Break the load，and connect the charger. When the charge current is higher than backlight on current，backlight blinking (if backlight on，means B- and P- of sampler are inversely) indicate battery is charging. Besides ， display charge current and remaining time.
When the charge or discharge current value is less than backlight off current，TK15 enter a low power state and backlight off. And TK15 will save the capacity(memory function). Click any one of the keys，backlight on 10s.
