  • Page 47 The long-life reference material is placed in a well inside the module, between sections A and B. The optical system periodically measures the reference and the results are monitored by the VIDAS to ensure that optical drift is minimal. Every 12 hours, the VIDAS carries out a calibration check, consisting of three readings of the solid standard.
