The TopDiag P180 is a versatile circuit tester for 9-30 V vehicles with AC/DC voltage, injector and battery tests, continuity testing and tone cable tracing.
Breakpoint detection (positioning)
The position of the open conductor can be quickly identified. Insert the tip of the probe into an open cable, send a sound signal to the cable, and follow the P181 wire finder from the wire to the tip of the probe to find the location of the breakpoint.
circuit breaker
Circuit breakers are short-circuit protected and their internal circuit breakers trip when they are overloaded.
AC RMS
This mode is used to measure AC voltages and can be used for any AC voltage or pulse waveform signal where RMS trimming voltage measurements are required.
AC-Pit-zu-Peak
AC peak-to-peak for any AC signal requiring peak-to-peak voltage measurement.
AC frequency
Frequency counter mode is used to measure the frequency or pulse width of AC signals for testing, e.g. MAF sensors, wheel sensors, etc.
Activate components
Can be used to activate starting fuel pumps, solenoids, blowers, cooling fans, headlights and other components.
Continuity test
Continuity testing is a quick way to see if the wiring in an automotive circuit system is connected or disconnected.
Injector test
This mode provides a full display of the injector circuit data so that the results of the injector test can be quickly displayed.
Voltage test
Extremely wide voltage range for various testing requirements. Supports 0-200 VDC voltage measurement and -100 VAC ~ +100 VAC voltage measurement.
Batteriediagnose
Multiple detection modes, more accurate detection data, safer travel.
Supports multiple languages
English, Simplified Chinese, Traditional Chinese, Japanese, Korean, French, German, Italian, Turkish, Polish, Indonesian, Spanish, Portuguese, Russian, Vietnamese, Thai, Arabic and many more.
