Morning...

After my last post about where to sound check my car, it was going to cost as much to drive anywhere as it was to buy one from ebay.

So i bought one... :)

It arrived yesterday, only prob is, I don't thyink it's calibrated correctly!?

Anyone know where or how I could calibrate it?

Thanks,

get a calibrated sound meter and test against that, or test against a known source, e.g. a hi fi at -58db etc
