PAT Check Boxes and Calibration
Over the years we have had added support for all PAT Testers that we have encountered into SimplyPats, this process requires that we cross check the data sent out from each PAT. One way of doing this was to make up our own individual check boxes with known values as pictured below.
You can also purchase off the shelf check boxes (similar to the one shown in the picture below)

Or if you really want to blow some cash, you can even go as far as to purchase your own purpose built Calibration Machine similar to our Transmille 3200A.
