The Com port used to communicate with the electrometer has to be defined (usually COM2) together with the default values for standard temperature and pressure factors for the correction factor for the ion chamber sensitivity. The characteristic of the kV, mA and delivery time for the QA Test beam are set together with the expected Baseline output from the test electrometer. Local rules for acceptability prior to treatment can be defined and these are typically 3% for simple acceptance and 5% for advisory acceptance. If required, the baseline value can be **normalised to unity** by the application of a calibration factor.
