I am not sure what a check-source is.....but there is a tester to make sure the unit is working when you turn the dial.

I'm not actually sure what you mean by "check-source". Please note, this unit is basically for gamma radiation only. To be calibrated it will need to be sent out. There they will adjust the individual controls for each corresponding range

Refer to the manufacturers owners manual online and get the model and serial numbers found on the unit to verify. It worked for me.

There is a certain amount of liability I would take by answering if your machine is accurate. I would suggest you do a charcoal test next to it to compare readings. Your first test that come back over 4.0 always makes you second guess any machine.

Yes. As Far As I Can Tell Via My Phone. I'll Check My Computer Records When I Get Home.(The One Nearest TheBulb Is The One I Replaced)

I don't think there is really a good way to tell. I just listen for the internal relay to click to let me know its ready.

Not positive, you can all check in the manuel. Sorry could ot be more help.

no unless you use the ohm meter function to check continuity. That could tell you if it's open or not.

It must be at home somewhere, assuming one came with the unit. I will look for it at home.

I don't thinks so,but you can always open the unit and look. Sorry if this is kinda vague but I don't try these type of things any more.

Truthfully I did not even check. If it did not work out of the box then I would have sent it back but otherwise the price was right. It has worked flawlessly but if it does fail it will already be out dated so I would just trash it and buy another.

Double check in the owners manual for hints. Or call the company for their take on this. If nothing else I concur with others, replace the unit.

I have no idea. I've had no trouble with this unit. I use it often with no issues.
