HL-GBJC*0　Pulse High Voltage Short Circuit Plate Short Circuit Tester
 
General introduction:
 
HL-GBJC*0 Plate short circuit tester provides unique test method to measure the safety distance between positive plate and negative plate duringassembly process. Short circuit can be dectectd duringassembly process before charge so that battery quality can be highly upgraded and loss from returned batteries caused by short circuit can be greatly lowered.Traditional high-voltage AC can also detect the problem by dielectrics test, but this way will easily damage the humid battery parts for the hotness.In order to overcome this limitation, Jinfan researched and developed a special tester for dielectrics test which can produce high voltage with short test time, thus average energy can be greatly saved and high voltage can be produced so that current can break down places with defects.Thistechnology can reliably detect battery with short circuit but will not cause damages to battery for the hotness.
 
Tester can have peak output of DC ***0V to meet requirements of different plates.Durable solid-state switch guarantees stability forfrequent operations, digital meter can display voltage and quality visually.The tester will indicate OK/NG only with simple steps, and operator does not need to make anyanalysis.The equipped safe high-voltage test probe will guarantee operators safety.When the tester has detected a defective battery, the high voltage will automatically switch off and at the same time the test will give an audible and visual alarm to tell operator to handle the defective battery.
Test characters:

This tester is used to testseparator insulation of each single cell and judge if a battery is qualified or not.
The maximum output voltage is ***0(adjustable and displayed byvoltmeter, which is nota sine curved wave，the tester can generate ahigh voltage and a high current pulse which can last for a short time**5, when the power is of *0hz, it will generate *0 pulses per second,*0pulses per second for *0Hz, each pulse can last *0 microseconds.Although each pulse generate a very high instant energy,but for the short time and each pulse control，so a good high voltage needed for the testing has been produced,which has helped with saving a high-powered test and ridding the problem of over-hot of batteries. 
Control and display：
1．输出电压(Voltmeter)：Display output voltage（0～***0V），which is the true peak
Voltage. when output terminals are connected with load，this voltage would be
Different for different loads，if short circuit happens，maybe this value will become zero，but this tester is still in working status.
2．电压调整(Adjust V)：used for adjusting output testing voltage（0～***0V），clockwise for increasing, anticlockwise for decreasing.
3．调零控制(Balance)：to make quality meter conformed to actual testing, usuallywhen without load, slowly adjust the knob，quality display will be**0.
4．试验键(Experiment)：For checking the leakage current on the Quality(质量).when the output voltage is ***0V without load, pressExperiment(试验), on the  Quality（质量）a current value will be displayed on the screen，this value should be **0, and theæ•…éšœ(alarm indicator) will not light.,
5．Trip level-灵敏度设置：this is used for setting differentdexterity for different battery or different plates, this is used for setting the plates insulation value
 
二、Principle of the tester
（1）Note:the tester has a three-pin plug(with grounding wire), it has been connected to a adaptable socket, otherwise it has to be grounded with an extra wire(from back—PE.
（2）After receiving the tester, carefully unpack the package and inspect anyhiding defect.Togetherwith the tester,there are quality certificate, operation manual, test lead, power line.To effectively check the operation of the tester and adjust the voltage to be 0, connect it with single phase power supply, connect red test lead with high voltage+ and black test lead with high voltage -，switch on the power supply.
For Voltage adjustment there should be values on the voltmeter, rotate the voltage knob, the value will become bigger, until the value reaches between ********0V, usually small-capacity battery will use this voltage for the test.Customers can also adjust the value accordingtheir requirement.With the setting ofbalance, quality meter will display a value，which is possibly positive or negative, anyway, rotate knob ofbalance to adjust the value to be nearly **0. for voltage ***0 or ****0V, also adjust this way when changing testing voltage.
（3）Make the red test lead short circuit with the black test lead, then operateset knob clockwise slowly, when you hear the ringing for the first time, this value is just the maximum insulation resistance ,namely the lowest sensitivity,counterclockwise rotate the knob to set the sensitivity according your specific requirement, but influence brought by some other factors such as batterychange or moisture should be allowed，if the testing happens under low moisture level, adjust the insulation resistance to be a little bigger, namely lower sensitivity, otherwise, higher sensitivity for the testing.
 
（4）connect the 2 test leads with cell（ignoring positive or negative），a spark will appear even for qualified cell when the leads touch it, which is just normal phenomenon.
（5）if everything is normal, readings onthe voltmeter and quality meter will also change, which is also quite normal.The tester will alarm (ringing) for metal particles on the plates, burrs, big holes inseparators, sunken and broken plates and disorderlyarrangement of plates. 
（6）ordinary high-voltage tester will damage insulation layer for the fact that it generates many high-voltage pulses per time, which will make the insulation layer become hot easily and burn separators, differently ,*****3.0 tester only release single interval high-voltage pulse, it can provide enough time for the separator to dispense heat, thus the separators will not be punctuated.
（8）the most difficult to found out are plate holes，cracks, all other defects can be figured out.
（9）some times the battery plates have been formed(plates are electricity conductive), sometimes have not(plates not electricity conductive) , for the latter, the test will be difficult, because the defect has to exist somewhere between positive plate and negative one，if the plates are not electricity conductive, there will be no spark caused by short circuit, so the short circuit will not be found out.
（*0）the tester will not test a single plate, it only test between a positive one and a negative one. 
 
三、safety and maintenance：
（1）This test has to be grounded，training to the operator is also very important and effective, which canto the maximum improve the safety and test accuracy. 
（2）each shift has to regulate the test at least one time
（3）check test leads everyday to guarantee no damages
 
 
 
Kilovolt meter: display preset high output voltage(*****0V)
Quality meter: before testing terminals contact battery, it is preset to be ZERO, When the battery is tested by tesing terminals, the lower this displayed value is, the worse the battery quality is. It is between *****0.
 
BALANCE: Preset quality value,  before testing it should be 0 Usually.
 
 
First you have ****2 qualified reference value from good batteries.and record the quality value of each battery.
For example
The quality value of the *0 qualified batteries are : ***0， ***5， ***0， ***5， ***1， ***0， ***5， ***5，***8， ***7。amongh them, the maximum value is**1， so （trip level）should be higher than***1，like,***5。The actual setting can be nearer to ***1, but reasonable tolerane and moisture should be taken into consideration., If quality value reachs or exceeds the preset scale(Trip level), the tester will give alarm.
