Automotive Multi-function Tester
This Automotive Multi-function Testeris a practical auxiliary tool designed for automotive electricaand line maintenance and testing.Can be used to test battery voltagevalue, voltage polarity, conductivity, check lamp, check motor, heel Traceand locate faults such as short circuits and poor ground contacts
Tips:Only applicable to 3.5-36V DC environment, do not use for all AC andgreater than 36V source environment
Polarity Detection Function:
Contact the tester probe with the unknownpolarity of the battery contact to be measured.if the LED on the instrument is bright red,Represents the measured contact with positivevoltage; Jo instrument the upper LED is brightgreen, indicating that the measured contact has anegative electrode voltage
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
Polarity Indicator:
LED Red light: The probe output positive "+voltage or test positive "+" voltage; LED Green light: The probe outputnegative "_" voltage or test is negative "_" voltage; LCD display: blue digitaldisplay, representing the current voltage value
Stainless Steel Probe
Use the advanced high-sensitivity probe to quickly and accurately detect electrical system problems
Drive switch:
Press "Up"end, probe output positive "+" power supply;Press "Down" end, probe output negative "_" power supply
Power Clip
Clamp the input power when it is used
Line length:14.7Ft
Covering the front to the rear of the vehicle, making it easy to test the entire vehicle circuit system
Grounding clamp
Can be used asgrounding,Can also be used withoutput negative
How to use:
( 1 ) Unplug the tester connection wire.
( 2 ) The red clip is connected to the positive terminal of the battery, andthe black clip is connected to the negative terminal of the battery;thereupon the blue digit shows the current battery voltage value, and turnon the front light; Connect inversely,The voltage value is not displayed,but the lamp is still on

Love this toolUse it any chance I get on my classic car with fuel injection ls swap. Let’s me know if my computer or even just a light wire is ground or positive 12vLet’s see see if my battery is charging. Let’s me test my electric fans etc awesome tool.Don’t just send power to just anythingUse with caution amd learn your car.

This little tool is great, the value is awesome considering the cost of name brand. Its super useful for testing curcuits, the only issue i have and im not sure if its by design or not but my lead maintains a constant voltage (around 1v) when just attached to the battery, (aka the tip has 1v at all times when not hitting the richer switch)So maybe not great if you’re working with sensitive electronics.Otherwise seems well built and easy to use!

I did not order this for me. I'm a retired electronics tech and I still have my standard tools for this.This was ordered for a friend that deals with strictly mechanical and vehicle wiring issues. He got back to me today and told me the reasons he considers this a fantastic tool and how he considers it well worth the money. He personally considers it a great tool and well worth the money.

Love the probe. It’s replacing a none led display unit. Easy to use.
