These are instructions from the Pullman site
* Place the internal measurement fingers of the callipers inside the basket
* Open out the callipers and wriggle them up and down slightly while trying gently to open the callipers as far as they will go, making sure the fingers are vertical and parallel with the inside of the filter basket.
* Take the reading when the callipers wont open any more with gentle force
* If your basket has a ridge for the portafilter spring to lock in to, take measurements both just above and just below the ridge
* Take 6 readings of each measurement, rotating the basket about 30 degrees each time. When you submit your order, include the smallest measurement from both above and below the ridge.
