Automotive Oscilloscope Use (French)

CP5950

The LK9155 Oscilloscope trainer has been designed to provide a platform on which automotive technicians can be trained to use an oscilloscope to capture and diagnose automotive waveforms. The unit is capable of generating several basic waveforms, sine, triangle, square wave, as well as a number of pre recorded waveforms. The unit also generates CAN bus signals – high and low.

The desk mounted unit is powered from an external plug top 12V power supply. It has a graphical  LCD display and two signal selection UP and DOWN button switches to the left of the display. Two additional button switches on the right of the display are used for waveform properties sub-selection for individual waveforms. The unit can be used with traditional oscilloscope probes or with 4mm ‘banana plug’ wires and connectors. The unit is housed in a rugged plastic case.

There are 4 outputs on the unit: Out 1, Out 2, CAN 1, CAN 2. Once the user has selected an appropriate waveform using the button switches and the LCD then the outputs signal(s) appear on the outputs.

The output signals at the time of release are:

 

  • Out 1: Sine wave – variable frequency
  • Out 1: Triangular wave – variable frequency
  • Out 1: Sine wave, Out 2:  irregular repetitive wave
  • Out 1: Camshaft
  • Out 1: Exhaust pressure
  • Out 1: Fuel pressure
  • Out 1: Fuel pressure regulator
  • Out 1: Injector current
  • Out 1: MAF sensor
  • Out 1: Turbo actuator
  • Out 1: Crankshaft
  • Out 1: ABS analogue
  • Out 1: Camshaft, Out 2: crankshaft
  • Out 1: PWM30%  – adjustable between 10% and 30%

CAN1 and CAN2 permanently give out repetitive CAN bus signals.
