KM10 Circuit Tester Key Features

1.Highly reliable and extremely easy to use with 6m long strong cable
2.Built-in flashlight enables you to work in the dark
3.LED screen allows you to read voltage, current and resistance at the fingertip​​
4.With 6 Meter long electronic cable, convenient to test from the front to the rear of the car
5.Test mode contain AV Voltage, DC Voltage, Current Resistance, LED, including most car circuit test system
6.Including Cigarette Lighter adaptor, battery test clips, easy to get battery supply from the car
7.Circuit Breaker Protection: Ability to Power Up Components. Automatically shut-off if current exceeds 5 Amperes, it design to protect an electrical circuit from damage caused by over-current, typically resulting from an overload or short circuit.
Warm Note: This probe is very sharp on the pointed end, easily to get hurt. Better to be more careful when performing.

Comparison between KM10 and PS100:

PS100 test without the diode but only the sound
PS100 transforms sound waveform when testing the alternating current (AC) adapter, the sound varies as waveform changes, while KM10 directly displays that.

KM10 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.

Signal Circuit Testing

For example , you suspect there is a problem with your M.A.P ? sensor circuit, then follow the procedure involved with testing this sensor.
*Set the tool in AC Voltage mode, using the probe tip with chassis ground or the auxiliary ground lead.
*Connect vacuum pump to MAP sensor
*Connect the probe tip to the MAP sensor ,
Positive terminal and observe the LCD readings which should be a sine wave in normal condition,
*Apply vacuum
*Release vacuum and observe the LCD readings
