17. Page 17 © Oxford Instruments 2012 CONFIDENTIAL The Business of Science ® Constant flow:15 l / h Flush:120 l / h The UV-Pro needs to be purged for approx. 30 minutes before recalibration. The flow timer is preset to 40 minutes and switches automatically from purge mode to constant flow. When using the UV-Pro on a regular (daily) base, the flush time might be less than mentioned above. Storing the UV-Pro for a longer time (weeks or months) will increase the flush time significantly. It might last 3-6 hours until consistent values are obtained. The reference element is P because it has the shortest wavelength. Argon flow PMI-MASTER PRO
