Frequency - Bosch MTS 5200 LAB SCOPE Manual

BOSCH MTS 5200 LAB SCOPE
Presented by Bob Pattengale
We just looked at a voltage waveform for a TPS using the MTS 5200 connected to a
demonstration board. Now let's look at a frequency waveform. A frequency waveform would be
useful in diagnosing such things as a MAF sensor on Ford vehicles or even a CKP signal during a
no start condition.
Pictured above you can see that waveform has a nice steady flat line. This flat line indicates that
we are measuring a solid signal that has been processed using average amounts.
In the screen capture above you can see that as the instructor turns the knob on the
demonstration board the frequency increases and then decreases. This action is simulating a
MAF sensor signal as the accelerator pedal is depressed then released.
