1.KM601 is ONLY for 12-24V vehicle battery electrical systems, and should NOT be used to test 110/220V household electric appliances; or, it will be damaged.
2. The LED and LCD pull no more than 100 milliamps of current, therefore when using this device as a test light or multimeter, it is safe for computers and airbags.
3.When powering-up components, you can increase the life of rocker switch in the tool if you first press the switch, and then contact the tip to the component. The arcing will take place at the tip instead of the metal contacts of the rocker switch.
8 Functional Modules
1. Oscilloscope (Oscilloscope) Test Module
Oscilloscope test function is mainly to test a variety of voltage signals, contains four kinds of functions, respectively, DC
voltage test, AC voltage test, frequency test, duty cycle test, except DC voltage, the other three are
Except DC voltage, the other three have waveform display mode, which is part of the oscilloscope function.

2. Multimeter Test Module
The multimeter test function module mainly tests resistor resistance and diode forward voltage. Among them, the resistance
measurement function also contains a continuity test function, i.e., when the resistance of the tested wire is less than 30 ohms, the host
When the resistance of the tested wire is less than 30 ohms, the buzzer of the main unit will alarm, which is used to measure whether the wire is disconnected or not.
3. Fuel Spray Nolle Test Module
Injector test function module is mainly to test the parameters of the injector signal, and can be switched by pressing the key
Waveform display and digital display mode.
4. Relay Test Module
The Relay Test Function Module tests and helps to identify whether a vehicle relay is functioning correctly, primarily through relay test cables, auxiliary earth wires and probes.
5. Battery Test Module
Battery test function module is mainly to test the car battery system, contains 3 functions, respectively, battery health test, battery start test, battery charging test, etc., so as to test the good or bad of the car battery
