Key features

• •【Polarity Recognition & Test/Activation Components & Grounding performance test】Power probe can automatically identify the positive and negative poles, such as the polarity of the test voltage, cables, and plugs.Circuit tester can also quickly check and activate components,detect ignition plugs,sensors,and check switches,relays and the on-off of diodes,fuses and circuits.It can also test the grounding performance and find the wrong ground connection immediately.
• •【Continuity test & Jumper Lead test & Tracking/Locating Short Circuit】Circuit tester can use the auxiliary ground lead to detect the on-off of the circuit,when encountering a control switch or open circuit,black clamp and auxiliary ground wire can be directly connected through the equipment for testing.When the component is short-circuited or overloaded, and lead to blown fuse or circuit breaker tripping, Circuit tester can help you trace the problem wires until the short is located.
• •【Overload Protection&Buzzer Warning&Double Insulation Protection】Overload protection of the electrical tester ensures the safety of the user and the battery by disconnecting the circuit and buzzing alarm.When the current exceeds 10A,it will automatically disconnect the current.circuit tester uses insulating materials that have passed the National Safety Compulsory Certification (CCC) to provide insulation protection,prevent electric shock,and measure with confidence,which is safe and reliable.
• •【Highly Sensitive Pen & Strong Bite Force Clip & 4 Meters Long Wire】Continuity tester has a high-sensitivity pen tip,made of sharp stainless steel,which can pierce the wire insulation layer to check the circuit.LED signal light of the circuit tester can better help you to test,the display is clear and clear at a glance.Red/black clip and the auxiliary ground lead clip have a strong bite force and are not easy to fall off during testing.Provide about 4 meters of electrical wire for easy use.
• •【Quick Self-Check & Easy Operation & Suitable For 6-24V Dc Test】Before starting to test circuits or components,you can quickly complete the self-check to determine the tool's functional usability.After a simple hook-up of the unit to the automotive tools's battery,automotive technician can conduct a positive or negative battery current to the tip by rocking the power switch forward or backward.The kit is suitable for 6-24V DC test,so please do not use it on AC voltage.
