You will need a 150mm Vernier caliper, a 150mm set square and a 100mm set square.
A straight faced piece of profile the same height as the Z section or taller or a piece of steel straight edge or the like; then lastly a Z section profile for measuring.
Place the long face of the 100 mm set square vertically between the Z section and the straight edge as shown in the picture. Lay the short edge of the 150 mm set square along the top face of the Z section. This will support the 100 mm set square’s short edge and stop it falling over - as shown in the picture.
Using the 150 mm vernier caliper, place one end of the internal measurement faces against the 100 mm set square, then wind out the vernier scale until you reach the end of the top rebate leg of the Z section with the other vernier internal measurement face - as shown in the picture. This will give you an accurate measurement to 0.1mm of the section width to allow you to set up Y notching accurately.
