    Scoping AC Pressures instead of gauges

    Seems like a lot of modern Air Conditioning Systems now, use a pressure transducers on the high pressure side that you should be able to t into with an oscilloscope and view the AC compressor output pressure changes as little humps in order to better see that a 5 cylinder AC compressor might have a even work load or internal issue if you already know you have a full charge and your high side gauge appears to flutter and pressure seem a little off. Is Anyone doing this, or are these AC pressure transducers garbage on most not responsive enough to provide useful data? Also If you got the front bumper fascia off the front of the car and have a thermal image r, It might be able to prove to customer whether some of the Condenser capillary tubes have become clogged up and whether or not you need a condenser or not before you sell the compressor job
