It seems it's "rebooting" continually.
I have one, and it does show the test screen when I first switch it on, but then of course it stops and you can use it...
I can't help you any further, tho... I'm sorry, I'm not competent enough.
Edit: actually I have a question: is it brand new? have you ever seen it working properly?
Also, try to switch it on without test leads, who knows?
But then, if it's new it's better to send it back, it really shouldn't do that.
