 Autel PS100 4 Working Modes

There are four modes to diagnose the electrical systems, which can be accessed by depressing the Mode Button and cycling through each one.

1. DC Voltage: While the tool in this mode, contact the probe tip to a circuit, then the LCD display will read the DC voltage with a resolution of 0.1 volt.
2. AC Voltage: While the tool in this mode, contact the probe tip to a circuit, then the LCD display will read the Max. voltage, the Min. voltage, frequency and duty cycle.
3. Resistance: While the tool in this mode, contact the probe tip to a circuit, then the LCD display will read the resistance between the tip and auxiliary ground lead.
4. Tone On/Off: While the tool in this mode, just do a quick press of the mode button to toggle the tone on or off. While quickly pressing (a quick press and release) the mode button, if a short high beep is heard, this means the audio tone is turned on. If a short low beep is heard, the audio tone is turned off. This function is invaluable when working in bright areas where LED illumination alone is not sufficient. The audio feature may be disengaged when desired, such as for applications where the tool will be connected to circuits for long periods of time and the audio could become annoying.
