Standardised Disc Sensitivity Method involves measuring the diameter of zones of inhibition with a ruler, with callipers, or with an automated zone reader

However, zones of inhibition may also be measured in relation to zone templates.

The Renaissance artist Giotto de BonDone was able to draw a perfect circle freehand. The less gifted may use this program to generate their zone templates.

How to add templates to a controlled document: This document contains instructions for adding templates to controlled Standard Operating Procedures (SOP).
