100 has rich functions, please check the following introduction:

4 modes to diagnose the electrical system: DC voltage, AC voltage, resistance, diode.

Voltage & Polarity Test: According to the LED light and sound after the probe tip touches the circuit, it can accurately judge the positive, negative, and open circuits.

Continuity Test: While the tool is in Resistance mode, using the probe tip with chassis ground or the auxiliary ground lead, continuity can be tested on wires and components attached or disconnected from the vehicle’s electrical system.

Signal Circuit Test: When the vehicle has a fault code, in order to quickly determine whether the fault is caused by a certain sensor circuit, you can use this tool to quickly draw a conclusion.

Find Short Circuit: A short can manifest itself as a blown fuse or a tripped electrical protection device. Use the probe tip to activate and energize each fuse contact. The contacts that trip the circuit breaker are shorted.

Find Bad Ground: Probe for suspected ground wires or touch probe tips. If the breaker has tripped, the circuit is most likely grounded.

Activate Component in your hand/ in the vehicle/ W/Ground

Test Trailer Lights and Connections: Check function and orientation of connectors and trailer lights

Red/Green Polarity Indicator: The red/green polarity LED illuminates when the probe tip voltage matches and is within ±0.8 volts of the battery voltage. It is additional information that may be of value to a technician.
