10. Self-Test Before Use
Before testing the circuit or auto parts, please make sure that the tool is
good and passes the self-test.
Self-Test Steps
：
1. Connect the device to the car battery. (as shown in the figure 1)
2.Connect the probe pin to the positive electrode of the battery, and the
foggy bi-color LED light should be red. The buzzer makes a rapid sound. (as
shown in the figure 2)
3.Connect the probe pin to the negative terminal of the battery, and the
foggy bi-color LED light should be green. The buzzer makes a low-frequency
sound. (as shown in the figure 3)
4. Activate the output function switch. When you press the power switch
forward, the probe will output positive battery power. The foggy bi-color LED
light should be red. The buzzer makes a rapid sound. Release the switch, the red
light should be off and the sound disappears. The probe's positive output
vanishes. (as shown in the figure 4)
5. Activate the output function switch, when you press the power switch
backward, the probe will output negative battery power. The foggy bi-color LED
light should be green. The buzzer makes a low-frequency sound. Release the
switch, and the green light should be off and the sound disappears. The probe's
negative output vanishes.
After the above self-test, if your tool can work normally, then you can use it
without worry.
