MilliporeSigma/Direct-Q 3 - Delay in water dispensing
I'm using the Millipore Direct Q 5 UV water system, and am trying to calibrate the flow rate. There is a delay in the water dispensing which is causing the "flow rate calculation" to be lower than it should be. Does anyone know how to fix this? Advise this member.

Ramsey/Autocheck 4000 - Communications
Currently receiving reports and free run messages from ports A and B, respectively. Noticed that serial ports have both Tx and Rx lines which indicates the possibility of sending commands and/or changing parameters remotely. We would like to send "print report" commands remotely. Is this possible? Advise this member.

Braun/Biotech Fermentor System - Water recirculation
I have a Biostat C bioreactor. The water recirculation pump was replaced a few months ago. The pump seems to not be working again only after a few runs. The pump turns slowly, and there's a low grinding sound. Has this happened to anyone before? What things can I do (if any) to prevent this happening again? Advise this member.
