and
B
ref
on Chart 4
(‘Drystar 5500/5503 Geometric Consistency Control Chart’). Refer to ‘Charts
for general radiography QC’ on page 242 .
These charts will be used for the annual quality test. For more information, refer to

Make sure to measure distance A from the left edge of the left line to the
right edge of the right line and distance B from the upper edge of the
upper line to the lower edge of the lower line.
We strongly recommend using a 30 cm (12 inch) machinist scale with
0.5 mm divisions (1/64 inch).
