Eagle tree data logger amp ?

[Shark413]

Hi, I have the Eagle Tree Elogger3 150amp version and I have seen spikes as high as 180amps on it. I sent numerous e-mails to Eagle Tree asking if this would damage the logger but they have not responded. When I first bought the logger I assumed it would stop recording once it hit 150amps, but it kept going all the way to 180amps. It would be nice if they would spell out the max amperage, I mean does 150amps mean it can take a constant 150amp reading with spikes up to ?? or what?
