Improvements and bug fixes

Now supports Windows 10.

Fixed: a bug potentially causing prolonged auto-recovery times after manual valve adjustment.

Changed: the allowed relative deviation of the inject flow rate was set to 7%. This prevents oscillations of the inject flow rate that were observed, on occasion, after large, abrupt changes in channel pressure when flowing organic solvents.

Please Note: A Windows 10 or Windows XP computer is required for this update. The firmware update tool is incompatible with Windows 8 operating system – using it with Windows 8 will render the Eclipse temporarily inoperable. Please contact support@wyatt.com for assistance.
