The KZYEE KM50 (Upgrade of KM10) kit is the most revolutionary circuit tester to date, which works off of 12-24 Volt sources, featuring DC Voltage, AC Voltage, Frequency, Duty Cycle, Fuel Injection Circuit Detection, Resistance, and Diode Especially, in AC Voltage, Frequency, Duty Cycle, and Fuel Inject Modes, users can long-press the mode button to switch between Waveform Display Mode and Digital Display Mode. Theis indeed the ultimate in power and affordability, allowing users to check circuitry in one single step. An absolute must for every technician who is looking for a fast and accurate solution to electrical systems diagnostic.

TIPS:

1.KM50 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.

Activating Components

In Your Hand or In The Vehicle

With a flip of the power switch, you have a hot instant/grounding for voltage & polarity testing. It powers up components such as windows, lights, starters, wipers, and so on. Simultaneously uses the hot lead and the ground wire to activate elements right in your hand.

Frequency Mode Press mode button to enter the menu and short short press the down button to place the cursor in the frequency mode, and short press the mode button to enter the frequency waveform display mode. The LCD display will show the min frequency, max frequency and display the signal waveform in real time.	Fuel Inject Mode Fuel Inject Mode is specifically set-up for fast and easy injector circuit diagnosis. One quick connection to the circuit and the KM50 will display all the needed fuel injector testing information. To reset the maximum and minimum values, press the mode button twice. In this mode, if it fails to detect a valid injection pulse, a bar symbol will display instead.	Duty Cycle Mode Press mode button to enter the menu andshort press the down button to place the cursor in the Duty Cycle mode, and press the mode button to switch it to waveform display. The LCD display will show the min duty cycle, max duty cycle, and display the signal waveform in real time.

UPDATED FEATURES


DC Voltage Mode DC mode is for testing DC (direct current) voltages. Voltage testing is as easy as contacting the probe tip to a circuit and reading the display. DC Mode is the mode that the KM50 can supply battery power or ground by pressing the rocker switch.	AC Voltage Mode The auxiliary ground wire is connected to one end of the circuit under test, and the probe contacts the other end of the test circuit. The LCD will display the max and mini voltage value, and display the signal waveform in real-time. You can adjust the sampling frequency by pressing the Up/Down Button.	Resistance Testing Mode The probe contacts one end of the measured resistance, and the auxiliary ground lead is connected to the other end of the measured resistance. The LCD will display the resistance between the tip and auxiliary ground lead. When resistance value is less than 30Ω, the instrument buzzer will alarm and the green LED will light. This function can be used as continuity test.	Diode Testing Mode Contact the probe tip to diode positive terminal, connect the auxiliary ground lead to the diode negative terminal, the screen will display the forward voltage drop, which indicates forward bias. If swapping the probe tip with auxiliary ground lead, the screen will not display voltage, which indicates reverse bias. It also displays the max and mini values during measurement.
