KZYEE KM10 Product Function:
There are four modes to diagnose the electrical systems, which can be accessed by depressing the Mode Button and cycling through each one.
✔️DC voltage
While the tool in this mode, contact the probe tip to a circuit, then the LCD display will read the DC voltage with a resolution of 0.1 volt.
✔️AC voltage
While the tool in this mode, contact the probe tip to a circuit, then the LCD display will read the Max. voltage, the Min. Voltage and frequency.
✔️Resistance
While the tool in this mode, contact the probe tip to a circuit, then the LCD display will read the resistance between the tip and auxiliary ground lead.
✔️Diode
In this mode, the probe tip contact the positive terminal of the diode, connect the auxiliary ground lead to the negative terminal of the diode, the screen will display the forward voltage drop, indicates the forward bias. If exchange the probe tip and auxiliary ground lead, the screen will not display the voltage, indicates the reversebias.

KM10 Electrical System Circuit Tester Functions:
1. Perform these functions: power injection, measuring, ground testing, polarity checking, continuity testing and component activation.
2. Read the AVO meter, voltage, current, and resistance easily.
3. Press the power switch lightly and get the instant heat ground lead to energize the electrical components, such as the cooling fan, relay etc.
4. Activate the components by using the hot wire and ground lead simultaneously.
5. Determine the positive, negative and open circuit quickly.
6. Test the bad ground contacts quickly, follow and locate short circuits without wasting the fuse.
7. Test the continuity of the power switch, relay and diode quickly.
8. Protect the tool from overload through the inner circuit breaker.
9. Allow you to work in the dark area by using the built-in head light.
10. Operate the tool without looking at the menu once users are familiar with the tone. Test along the vehicle by the long cable.
Master Component Activation:
With a simple activation, you can power up components with ease – flip on lights, spin motors, swipe wipers, and get those radiator fans whirring and so on. This versatile electrical circuit tester is the ultimate DIYer’s dream, ensuring you save big on repairs by diagnosing issues firsthand. Experience the thrill of troubleshooting like a pro – all without leaving your garage. Invest in the KM10 automotive electrical tool and watch your car care worries disappear into the rearview mirror.
Short-Circuit Proof:
Protect your automotive investment with our advanced electrical circuit tester. When the load gets heavy, its internal circuit breaker trips, automatically shutting down to prevent damage. With a simple restart, you’re back in business, keeping your car’s electronics and your tester safe. Drive on with confidence – safety is now a standard feature in your garage!

Resistance Test: While the tool in this mode, contact the probe tip to a circuit, then the LCD display will read the resistance between the tip and auxiliary ground lead.
Diode Test: In this mode, the probe tip contact the positive terminal of the diode, connect the auxiliary ground lead to the negative terminal of the diode, the screen will display the forward voltage drop, indicates the forward bias. If exchange the probe tip and auxiliary ground lead, the screen will not display the voltage, indicates the reverse bias.
Signal Circuit Testing: Once you extract a DTC from the vehicle and realize that troubleshooting begins with some kind of sensor circuit, there is a quick test you can perform to verify the code. Testing your sensor is easy while using the tool.
Testing Trailer Lights and Connections: While the tool in DC Voltage mode, clip the auxiliary ground lead to the trailer ground , probe the contacts at the jack and then apply voltage to the probe tip. This lets you check the function and orientation of the connector and trailer lights.
Red/Green Polarity LED: The Red/Green Polarity LED lights up when the probe tip voltage matches the battery voltage within ±0.4 volts. It is added information that could be valuable to the technician.
Auto Circuit Breaker: The tool is short-circuit protected. Its internal circuit breaker will trip if it becomes overload. The circuit breaker is a valuable test tool as well as a safety measure to protect the tool from overload.
