Hi please could someone tell me where I can find the drain check ,I downloaded the beta version and loaded it onto pc but still don't see the drain check .
Regards
Danny
I followed one of the links in Steve,s post ,in library under guided tests it gives a parasitic drain check under guided diagnostics in beta format. I downloaded the latest beta but cannot find it in beta diagnostics nor the beat automotive .
It was just something I wanted to try as I had mondeo draining today .
I ended up reverting to clamp and meter it just looked a great test.

There have been a few articles on this topic. Using the Amp Clamp has limitations as ambient temperatures and the Amp Clamp Battery will drift over time. Especially if you are testing over extended periods of time - overnight for instance.
You can the scope the Volt Drop across the resistor on one channel and the battery voltage on another. Next create a Math Channel using ohms law to determine Current ( a stable voltage battery support unit is a good optional extra to the test)
Then it is a case of Current = Voltage / Resistance which the correctly configured Math Channel will display for you.
Here is a thread that goes into some detail topic9482.html
Hope that helps
