DESCRIPTION
Description:

TF03K is a kind of high accuracy current type battery indicator, TF03K can test the voltage, current and capacity of lead-acid/lithium-ion battery, and display them with intuitive battery symbol and percentage. Users can know the state of battery in time. TF03K has function of memory. This battery indicator is suitable for mobile and portable equipments, ups, electric vehicles, ebike, battery cars, balance cars, cleaning machines and so on.
      TF03K is different with voltage type battery indicator, TF03K has high accuracy and high reliability. So it is expensive than voltage type battery indicator like LY4,LY6......

Install:
 
1. In the device panel to open a rectangular hole and two screw holes,
2. Then install the battery indicator from the front of the panel and place the indicator housing into the rectangular opening.
 
Connect:
 
1. Prepare a shielded wire and a wire (0.3-0.75 mm2);
2. One end of the wire connects to B+ of battery;
3. Another end connects to B+ of sampler (any one is ok);
4. The B- of sampler connects to B- of battery;
5. P- of sampler connect to P- of output;
6. Finally connect sampler to indicator by the shielded wire.

Use setting:
 
Capacity and voltage setting:
1. Press the "OK" key for 3s to enter the setting menu;
2.Click the “up”or“down” key to select the setting items:       

CAP—capacity setting: an initial capacity has been set at factory, please set it according to the real capacity;
       FULL U—full voltage setting: when the voltage is higher than it the percentage will be 100%;
       ZERO_U—zero_voltage setting: when the voltage is lower than it the percentage will be 0%, backlight off , if you keep discharge the LCD flicker, the alarm indicator display and buzzer warning;
       Alarm—alarm setting: when the capacity is lower than it the LCD flicker and buzzer warning.
       Note: Generally the FULL U and ZERO_U do not need to set. The default is 0V, which is the invalid. If you want set, please understand the actual charge and discharge voltage of battery firstly. 
3. Select“CAP”and click“OK”key to enter the capacity setting; The set bit flicker, click the“OK”key can select other bits, click the“up”or“down” key to plus and minus the value; after this click the“back”key to quit capacity setting;
4. We can set other items with the same method as capacity. When all the items are set and all the values are correct, click the "back" key to save the set and quit the setting menu;
5. Cut off and Re-power, it will work normally.

Package included:

1 x coulomb counter
1 x sampler
1 x 1M shielded wire
