Say doc I have always wanted to see that industry standard medical measuring device that you guys use to determine our sanity.

Any chance you have the model number of that device or maybe even a manual laying around we could peruse through?

How is that device calibrated and how long is the training, testing, and certification to be qualified to operate this said industry standard measuring device?

If you get trained and certified on brand A can you legally operate brand B? Do you need to be trained and certified on both brands?

How long does your certification last and what do the recurrent training classes include?

Asking for a friend.
