The TopDiag P100 is a circuit tester designed for diagnosing 6V to 30V electrical systems in vehicles. The device is equipped with a TFT color screen for clear display of measurement values. The P100 can perform various measurements, including testing DC voltage up to 65V, AC voltage with display of frequency and duty cycle, resistance up to 200 KΩ, and diode testing.
This circuit tester offers the ability to activate components by supplying positive or negative voltage directly through the probe. Features such as detecting short circuits and checking for poor ground connections are integrated. The device is protected against overload with a self-resetting thermal fuse of 8A. The interface is adjustable in multiple languages and the device comes with a 10-meter long extension cable for a wide working range.
Application and functionality:
The P100 is developed for performing various measurements and tests on the electrical circuit of vehicles.
- Voltage and polarity testing: For measuring DC and AC voltage, identifying positive and negative circuits, and checking ground connections.
- Resistance and continuity testing: For measuring wiring, switches, relays, and other components for breaks or resistance.
- Component activation: For directly driving electrical components such as fans, motors, and lamps by supplying power or ground through the probe.
- Short circuit tracing: For locating short circuits in wiring without having to remove fuses.
- Trailer lighting testing: For checking the functionality of trailer lighting and connections.
Measurement ranges and functions:
The device features various measurement modes for broad applicability.
- DC voltage measurement: Measures direct voltage in a range of 0 to 65 volts.
- AC voltage measurement: Measures alternating voltage and displays minimum and maximum voltage, frequency, and duty cycle.
- Resistance measurement: Measures resistance in a range of 0 to 200 KΩ.
- Diode test: Checks the functionality of diodes.
- Overload protection: An integrated, self-resetting thermal fuse protects the device and vehicle circuit at a current of more than 8 amperes.
