We use it in vehicle AC systems, as well. It's not harmful to the AC system and won't contaminate it, and it allows you to spray the system with soap and water without running the risk of it getting into the refrigeration system low side, since the entire system is charged to 250 psi of positive pressure.
It depends on what type of circuit board, the symptoms and the application of the board. Otherwise, most technicians will use a good test meter and/or an oscilloscope, or a plug-in diagnostic system (computerized or stand alone).
A virtual machine will provide generic hardware that can be found in many other computers. Having a virtual machine eliminates the need to have either a second system, or to reboot to test their operating system.
Yes, I had this test also.

The Demand Test is NOT part of the DURCH test. WHOEVER WROTE THAT ANSWER IS A GIANT LIAR! REAL ANSWER: The Compliance Test is NOT part of the DURCH test. I know that this is correct because i just took a test and this answer made me fail that question.
It depends we test the lines with 300 PSI nitrogen, leak check system, and at times let it sit for 24 hours. Then come back and evacuate system before opening charge.

the most sensitive method for a quantifiable leak test depending on the service of the system.
Pressure test system and watch for leak
pressure test the cooling system
A coolant pressure test is used to detect a leak on the coolant system.
A vacuum

Your heater core has a leak, have the station pressure test your cooling system if it does not hold pressure you a leak in system
Pressure test system to determine where leak orginates to determine fix
Well if that is the code you are getting when using a scan tool , it means there is a leak somewhere in the fuel/evap system. To actually pinpoint the leak, you would have to do a "smoke test" to see where the actual leak is taking place. That type of test really needs to be done by a mechanic that has the equipment to do it.
