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

Sensationell gutes Gerät für die Fehlersuche bei der Kfz Elektrik. Strom durch die Leitung schicken, Durchgabgsprüfung und Spannung auf + / - kann gemessen werden.

Packaging The 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 Look Looking 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 use The 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 settings DC Voltage, AC Voltage, Resistance and Diode Just 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 circuit The AC Voltage does the same but for AC Voltage The 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 diode I 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.

Great tool easy to use

Works good
