1pcs 1.2-12V battery capacity tester external load discharge capacity test 18650

 

Detailed parameters:

 
Power supply voltage: DC4.5-6 v (micro USB interface)
 
Working current: no more than 70 ma
 
Discharge voltage: 1.00 V to 1.00 V resolution of 0.01 V
 
Termination voltage range: 0.5 to 11.0 V
 
Supported by current: 3.000 A maximum resolution of 0.001 A
 
Maximum error voltage measurements: 1% + 0.03 V
 
Current measuring maximum error: 2% + 0.010 A
 
Maximum range of battery capacity: 9999 ah ah (1 = 1000 mah) value is through the larger decimal point shift switch， when less than 10 ah is shown as 7.0.x.x XX， reach more than 10 ah shown for XX， XX， and so on.
 
Circuit board size: 50 mmx34mm
 
Finished size: 50 mmx36mmx17mm (length X width X height maximum position size， contains copper foot height)
 
 
 
Method of use:
 
1. The measured battery should be charged in the first place.
 
2. Connect the battery to be tested is the positive to the input， the cathode to anode， input cannot meet the (load after the may damage the circuit). Connect the load to the output positive and negative， to the tester for micro USB communication work power (do not use a desktop or laptop USB power supply)， the battery voltage at this time.
 
3. Direct start test just need to press the "OK" button， automatically according to the battery full charge pressure tester is able to develop appropriate termination voltage， and then launch the test will display flashing 3 times. Need artificial formulated only requires termination voltage battery voltage display state， press the "+" or "-" buttons to modify， termination voltage display for ps， on behalf of the voltage value behind， and the resolution is 0.1 V， set after press "OK" to start testing.
 
4. Load test after the start of tester is available to control the electronic switch， the testing process according to data on discharge capacity (Ah)， the discharge current and battery voltage (V) (A) between the wheels. When the battery voltage to set after termination voltage tester to cut off the load control switch， and display the data stays above the capacity (Ah) and fast with corresponding indicator light flashing， displayed the actual discharge capacity is the capacity of the battery， press the "OK" may terminate flashing let data stability， according to press the "OK" button to return to again just on electricity state can replace the battery test in the next section... 
The error code and meaning:
 
Err1: the battery voltage is higher than 15 v
 
Err2: the battery voltage is lower than set end voltage
 
Err3: the battery cannot afford to load or discharge current line resistance is too big
 
Err4: current is too large (current over 3.1 A)
 
 
Secondary calibration operation (to run after calibration， represents to abandon the warranty) :
 
Three keys to hold down the tester electricity at the same time， enter the calibration mode， the first number after calibration records to show into formal calibration show 0 u0a sampling program， the sub input is negative after press the "OK" button， complete show J10u， to 10.00 V dc voltage applied between the input is negative after press the "OK" button， displayed after J2.0 A， anode (flow direction) to the output and input the cathode (flow direction) 2.0 A constant dc voltage applied after press the "OK" button to complete the calibration. Tester will to pre-approval of calibration data， if the calibration data， will in turn show four calibration after several exit， if pre-approval think data unreliable， it discards the data out.
