The light and compact pulse checker is a must have for any auto-electrician, as it's main purpose is to quickly test the pulse output of any electronic component in the vehicle without the need for expensive equipment such as oscilloscopes.
It can quickly diagnose Crank Angle Sensor pulses, Cam Sensor pulses, Distributor Magnetic and Hall sensor pulses, as well as Ignition Coil Pulses and Injector Pulses for Pulse Presence, Frequency and Voltage level.
It can also be used to check various computer signals for voltage levels and pulsing. Due to its design containing an internal battery, it is also able to test trailer and light wiring without connecting to the car battery.
