With differential inputs
All TiePie engineering automotive oscilloscopes, like the Automotive Test Scope ATS610004DWXMSG, have differential input channels. The ground terminals of the inputs are not connected to each other and also not connected to the ground of the PC. When the instrument is accidentally connected wrong, no short circuit is created, there will flow no short circuit current and expensive extra repairs because of damaged car electronics are history.
Using additional tools
When besides the automotive oscilloscope also e.g. a fault code scanner is connected to the computer, differential inputs on the
automotive oscilloscope are even more important.
The fault code scanner is connected to the ground of the car battery and also to the ground of the computer. With a standard
automotive oscilloscope, the input channels are connected to the ground of the battery. When the fault code scanner is connected
to the car, and the ground of an input channel of the automotive oscilloscope is accidentally connected to a point carrying a
voltage, not to ground, a short circuit is created. The car wiring, the computer and the fault code scanner can be damaged by the
very large current that will flow.
When using a TiePie engineering automotive oscilloscope with differential inputs, no short circuit will be created, so no large
current will flow and no damage will occur.
Conclusion
Always use an automotive oscilloscope with differential inputs to prevent damage on your car caused by a connection mistake,
because differential inputs have the following advantages:
the ground terminals of the input channels are not connected to each other
both input and ground terminal of each input channel have a high input impedance
It is therefore highly recommended to always use an automotive oscilloscope with differential inputs to avoid short circuits and
expensive damage to the car electronics.
