Finished size: 50mm x 37mm x 17mm (long x wide x high position size, including copper foot height)


Method of use:
-the battery being tested should be filled first with electricity.
-connect the positive to positive, negative to negative, non-opposable battery (with load and counter-reaction may damage the circuit)Connect the load to the output positive and negative poles, supply the tester micro usb to work power (not available on desktop or laptop usb), when the battery voltage is displayed.
-direct start test only requires clicking ok button, the tester can automatically set the appropriate stop voltage according to battery full voltage, and will flicker display 3 times to start the test.The termination voltage will only need to be fixed manually by pressing+or-button modification in battery voltage display state. the termination voltage will be shown at the beginning of p, followed by voltage value, resolution 0.1v, and then click ok to start testing.
-the tester is connected to the electronic switch that controls the load after the test starts, and the test process data show a rotation between the diskharge capacity (ah), the current diskharge current (a) and the battery voltage (v).When the battery voltage reaches the set termination voltage, the tester diskonnects the load control switch and displays the data at capacity(Ah)Above and with the corresponding indicator, the display capacity is the actual diskharge capacity of the battery, click ok can stop flashing to stabilize the data, press ok button to return to the new electrical state can replace the battery test next section...
Error code and meaning:
Err1: battery voltage above 15v
Err2: battery voltage below set termination voltage
Err3: battery cannot withstand load diskharge current or circuit obstruction
Err4: excessive current (current above 3.1a)
Secondary calibration operations:
Press three keys to power the tester,Access to calibration mode,First show the number of calibration records and then enter the formal calibration sampling program to display 0u0a,Click ok button after short input positive or negative pole,Completion of display j10u,Press ok button after applying 10.00 v standard dc voltage between input and negative poles,Later display j2.0a,Negative output pole(Direction of inflows)And input negative poles(Direction of outflow)Apply 2.0 a constant dc current and press ok button to complete c
