Feature: 1. Automotive Circuit Tester: Automotive Circuit Testercan quickly detect various communication line signals, sensor signals, as well as various test lamp tests and voltage measurements, making it the best electrical tester for 0-45V circuit system detection and maintenance. 2. Convenient to Carry: TopDiag p50pro automobile circuit testing pen is compact, portable and easy to carry. The MiNi oscilloscope is small-sized, high accuracy, supports AC/DC signal mode, and a frequency range of 10Hz and 200KHz, making it easy to detect and repair various sensor faults in vehicles. 3. AC/DC Testing: Supports DC and AC voltage test, and can record the maximum and minimum voltage values during the measurement process, which is very convenient. 4. Multifunctional test light: Supports 5W power test light, LED test light, multiple test light modes, to meet different line testing needs. 5. Flashlight: Imported beads with high brightness and low power consumption, illuminate the working area in front of the probe in dark places.
