I lost the directions for my Mastercraft Pinless Moisture Meter. I cant seem to turn it on.Thought maybe it was the battery and thought I would change that but no luck. Maybe I am not turning it on correctly. I can give you the model number but unfortunately you don't have the product type listed. Is there anything you can send me showing or detailing how to turn it on so I can make sure I am trying to it right. Many thanks.
