DC voltage mode. The DC mode is used to test the DC (DC) voltage. Voltage testing is as easy as touching the probe tip with the circuit and reading the display. DC mode is a mode in which KM50 can power the battery or ground by pressing the rocker switch.

Connect the tip of the probe to the positive terminal of the diode and the auxiliary ground wire to the negative terminal of the diode. The screen will display a forward voltage drop, indicating a forward bias. If you swap the probe tip with the auxiliary ground wire, the screen will not display the voltage, which indicates that the

The fuel injection mode is specifically set up for quick and easy injector circuit diagnosis. Quickly connect to the circuit and KM50 will display all required injector test information. To reset the maximum and minimum values, press the mode button twice. In this mode, if a valid injection pulse is not detected, a bar symbol will be displayed.
