Product Overviews

This is a kind of high precision current type battery capacity tester(also known as coulometer)，which can test the voltage，current and capacity of battery to help users know the state of battery in time. It have memory function. It is suitable for mobile and portable equipments、e-bike、balance cars、cleaning machines、instruments、ups and so on.

It is suitable for lithium batteries, lithium iron phosphate batteries, lead-acid batteries and nickel-metal hydride batteries which working voltage is from 8V to 100V.

Connect

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.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). Finally connect sampler to battery monitor by the shielded wire. After confirm and power on, it will be work normally.

Using steps

1. Connect and check the current

Power on after complete the connection as shown, the screen should display capacity percentage. If the screen has no response, please check the connection. Then charge or discharge the battery, and check whether the display current is equal to the actual current. If the deviation is large please check the connection.

2.Capacity reset

On first use, the percentage and capacity are not the actual value, you should reset the capacity: discharge the battery totally and hold the”V”key for 3 seconds to set the capacity zero or charge the battery fully and hold the ” %”key for 3 seconds to set the capacity full. And it doesn’t need to do this again later, except replace the battery.

3.Check and reset the actual capacity

If you find the display capacity don’t match the actual capacity，please check and reset the actual capacity：discharge the battery totally and hold the”V “key for 3s to set the capacity zero，then set the capacity value as large as possible. Then charge the battery fully，and the display capacity is the actual capacity. Finally set the display capacity as preset capacity (Please refer to use and setting).

Use and setting

Attention

When charging or discharging，the coulometer must be at work. Otherwise the capacity will not be accurate. When the charge or discharge current is less than backlight off current, coulometer enter a low power state and backlight off. And it can memory the capacity.Because of high sensitivity，when the coulometer is in standby mode (battery has no input or output current)，if it is interfered by electromagnetic radiation (open or close inductive loads，such as the motor) nearly，the backlight will shortly open. When the current changes frequently the date acquisition may produce error，and it will affect the accuracy.The tester cannot be exposed in the sun for a long time or in the environment with large amounts of ultraviolet radiation when using or storing，particular in winter (＜-20℃) and summer (>60℃) otherwise it will shorten the life of LCD.

Other description

2. Connect the load，when the discharge current is higher than backlight on current, the backlight on (if backlight blinking，the RS+ and RS- are inversely), and display discharge indicator ,indicate battery is discharging. (Picture 1)Break the load, and connect the charger. When the charge current is higher than backlight on current, backlight blinking (if backlight on，the RS+ and RS- are inversely), and display charge indicator ,indicate battery is charging.
