【HAS LONG TEST LEAD】Electrical System Analyzer has long test lead. The cable length is about 5m(16ft) which allows you test any electrical system easily.

【OVERLOAD PROTECTION】Car Electrical Diagnostic Tool Overload Protection: When the current exceeds 8A, the unit will disconnect the current automatically.

【WIDELY APPLICATION】Auto Circuit Breaker Tester can test for continuity. Test for polarity of a voltage. Check switches, relays and the on-off of diodes, fuses and circuits . Test for polarity of electric cables and plugs. Track and locate short circuits. Test for bad ground contacts.

【LONG TEST LEAD】 Automotive Diagnostic Scanner, the cable length is about 5m(16ft) which allows you test any electrical system easily. Operation Instrcution: Unroll the unit's cable. Clamp the red clip to the positive terminal of the vehicle's battery. Clamp the black clip to the negative terminal of the vehicle's battery.

【WITH AN ALARM SOUND】Auto Electrical Diagnostic Scanner made by the item indicates that the circuit breaker trips off. After the circuit breaker trips, it will reset automatically within 3 to 5 seconds. After an alarm sound, if this item is still connected with the testing object and you keep pressing down the switch, the circuit breaker will repeat the process of trip and reset automatically.

【LOCATING OPEN CIRCUIT】Open Wire Detector, powered by 2pcs*9V Batteries. It detects and alerts you immediately where a circuit is open. You can quickly and easily Locate short circuits, open connections, broken wires, current leaks and even trace wires. Transmitter and receiver LEDs show open or short circuit conditions.

【CHECKING SHORT CIRCUIT】Short Circuit Finder Automotive,you can also find intermittent circuit problems by flexing wires or connectors and listening for a change in the receiver tone, 7 inch Flexible Probe Help Reaching Wires in Congested Places.

【SUITABLE FOR DC 6~42 Volt CIRCUIT POWER】Electrical Circuit Tracer will work on all kinds of circuits with voltages between 6 and 42 volt DC. (such as those found in automobiles,trucks,tractors,boats,RVs,etc...With its wide working voltage range.).

【EASY TO USE & CARRY】The multimeter seems to work great and it is a perfect size to keep in your glove box/travel tool box or where ever you may need it.

【MULTI-FUNCTIONALS】Mini digital dc voltmeter is great little DMM, it has all the needed functions.DC Volts, AC Volts, Ohms, Amps and continuity testing with tone.

【MANUAL & REMOVE TAPE】The small multi meter is no auto off and not auto-ranging, before operating the first time, you need to remove the tape insulating the battery.

【ACCURATELY MEASURES】Pocket Multimeter Mini designed to measure DC and AC voltage, DC and AC current, resistance, continuity, diode, capacitance, and frequency, data hold, and automatic power-off. Sampling Rate is about 3 times/sec.

【NON-CONTACT AC VPLTAGE DETECTION】Mini Tester NCV Sensor used in non-contact ac voltage detection. It is located at the mark " NCV " which is just beside the LCD display.

【100% Safety Assurance】Pocket Electrical Meter built-in 500mA/250V Fuse. Overload Protection on all ranges. Max. Allowable Input Current: 400mA; Frequency Range: 40Hz to 400Hz.

【POWER SUPPLY】The power probe is powered by the circuit under test. Power Supply by 5 to 15V battery. Power Supply protection is 20VDC/VAC.

【LED LIGHT&AUDIO INDICATIONS】This logic troubleshooting instrument will give visual (LED light) and audio indications for logic levels and pulses.

【PULSE WIDTH】The test light automotive can capture pulse width as short as 30 nanoseconds on frequency 20KHz-20MHz. Maximum Input Voltage is 40VDC/VAC(duration<25 seconds.

The device is useful in vehicle¡¯s fault diagnosis and service: battery load test, cold temp.effects, battery load test analysis, charging voltage test (12V system only), starter motor test (12V system only).

Test batteries from 300-1000 CCA, operating range from 6-12 volts.

Compared with other pointer type battery tester, our bright digit LED display is great for bright- or low-light environment, which is easy to read the measurement result.
