Automotive Circuit Tester KM10 Professional Power Circuit Probe Kit - DC/AC Current Resistance Diodes Vehicle Voltage Signal Diagnostic Activating Components Tools for 12V to 24V Electrical System

Funciona todo bien menos que no mide resistencias solo sirve para comprobar continuidad

PackagingThe tester came in a cardboard outer sleeve. Once removed you will find a hard-plastic case that holds the tester unit and the accessories.Upon opening the box you notice how well the unit is fitted in there with a nice thick foam insert in the lid.First LookLooking at the unit you see how well it looks and some of the nice design features it has with the colour screen and the removable probe along with a massive 20ft extension cable.It has all the connections you need, Direct from the battery or from the included lighter socket adapter.First useThe unit was powered by the lighter socket and booted up into the menu in a second.You are presented with a nice clear colour display and 4 menu options at the top of the screen. The unit has 2 led's on the top of it giving you some light to work with.You select the menu option with the round menu button on the device.The menu runs through the following settingsDC Voltage, AC Voltage, Resistance and DiodeJust press the menu button until you see the correct screen.With the probe in DC Voltage it allows you to read the DC Voltage of a circuitThe AC Voltage does the same but for AC VoltageThe Resistance mode enables you to check the resistance between the tip and the Aux ground Lead.In this mode you can check the voltage drop from positive to negative on a diodeI used the probe to check a few headlight bulbs I had lying around not knowing if they were out or not.I connected the Aux cable from the probe to the negative on the bulb and touched the tip to the positive, this allowed me to check the circuit. The screen went green confirming no issues with the continuity of the bulb I then pushed forward on the toggle switch and applied voltage to the bulb lighting it up.A quick two-minute task is completed with the tester saving a lot of time and effort.My Thoughts,All in all a solid bit of kit with easy to use features and a easy to use menu. A Good design aesthetic and all stored in hard plastic case. a must for anyone who works on electrical systems.

Das Gerät kommt in einem Plastikkoffer, was sehr praktisch ist.Im Lieferumfang sind:- der Tester selbst,- die Messspitze, die in dem Gerät verstaut wird,- ein Verlängerungskabel,- zwei Kabel für Stromversorgung des Gerätes: eins ist für Zigarettenanzünder und das zweite mit Klemmen ist für Anschließen direkt an die Batterie,- eine englische Anleitung.Alle Teile sind gut verarbeitet und sind aus robusten Materialien hergestellt.Das Gerät dient zum Überprüfen der Spannung des Bordnetzes, Messung der Widerstände, Prüfung der Dioden und für die Suche des Spannungslecks (Voltage Drops).

I had used it for about a year, no major issues. My only issue with the design is the length of the grounding cable, just a bit short for what I usually need it for, but I've been able to make it work with an extra wire. The only real problem I came across was when I had made the mistake of trying to apply power or ground to a wire when it had the other already active. User error, really. But it was when I kept doing it when I had to apply one of the two before making contact, like in a tight space. It would normally shut down and restart if you made a mistake, like normal. But I had done it quite a few times in a row and it had shut down completely. Few days later, it starting working again, but sometimes when you power it, it doesn't show or do anything on the screen but a blank background. Again, user error caused it. But other than that, having it as a mobile mechanic has saved me so much time, being able to see what is actually happening. I only have the KM10, but I honestly might upgrade to see what I can use the nicer model for. It was well worth the price.

Very good packagingTool came with a plastic case. I found this tester very convenient for a few applications that weren't readily usable with a regular multimeter. Being able to activate electrical components remotely on my Jeep was extremely cool. I like that it had such a long cord included. I can see where that will be usefulLove this tool.
