Application Description:

CNBJ-823 is a practical auxiliary tool designed for automotive electricaland line maintenance and testing. Can be used to test battery voltage value, voltage polarity, conductivity, check lamp, check motor, heel Trace and locate faults such as short circuits and poor ground contacts.

Product features :

1 . Front lighting: Only need to put the red and black clips on the positive and negative clips on the car's battery the electrode can be used, which is convenient for detection and maintenance in the dark place, and can also be used as a lighting lamp.

2 . Voltage display : the red and black clips can be printed on the positive electrode " + " and      negative electrode " - " . the voltage value of the storage battery is displayed in blue digits;

3 . Voltage polarity test: Without pressing the key on the tester, it can be used before the tester the surface probe probes the unknown polarity contact ( contact ) on the car to check whether it is charged or positive Polarity ( LED bright red ) or negative polarity ( LED bright green);

4 . Polarity output : Press the ammonium bond on the tester ( front pressure "▲" or back pressure "▼"  ). Make the probe on the tester with a positive voltage ( LED bright red ) or a negative voltage ( LED bright Green ) . At this time, the dimensional device can be checked     according to the electrical polarity of the device to be repaired and test components grounding status; For example, with the negative electrode " one " auxiliary power supply clip (black small crocodile wire clip), you can test the components offline, as well as detect the electrical wiring of the components On off.

5 . Overload power off protection: If the current is too large or the load is too large in the power distribution process, the LED will be instantaneous Change from red to green with a buzzer warning that should be disconnected or tested for protection storage battery;

6 . Super long test cable: The cable length is about 4.5 meters, which allows you to easily test any part of the car electrical system.

Tips and Warnings

1 . Only applicable to 3.5-36V DC environment, do not use for all AC and greater than 36V source environments;

2 . In the process of use, the probe may spark, please do not exist around the flammable gas body, dust and flammable and explosive environment use;

3 . If the pen or test wire is found to be damaged during use, please stop using;

4 . The tip of the probe is sharp, and pay attention to safety during use and storage.
