49iQPS Plumbing Bulletin: (49iQPS Zero air plumbing)
Thermo Scientific 49iQ Ozone Primary Standards shipped prior to 06/01/2019 were manufactured with a minor zero air plumbing configuration error that can affect the operation of the calibrator depending on the zero air pressure supplied to the calibrator.
49iQPS Plumbing update: (Addition of a second sample capillary in the 49iQPS)
We have received feedback that some Thermo Scientific 49iQPS instruments are exhibiting erroneous ozone concentrations. This appears to be related to long pieces of tubing connected to the vent, resulting in back pressure that impedes flow through the unit. A solution has been identified and all new units have this modification installed. Units in the field can be retrofitted by installing an upgrade kit.
ePort Software: (iQ Firmware update from V1.6.11 using ePort software)
The USB firmware update method will not work on instruments currently running iQ Series firmware version 188.8.131.52737. To upgrade any of the iQ instruments from version V184.108.40.206737, you must use ePort software to do a firmware update.
