I picked up a Motion Pro a while back to use in place of my Ancient Mercury Manometer. All has been well until today. I noted that the fluid, over time was gradually traveling higher and higher in the tubes and that #4 was now at it's adjustment limit. Calibration was one of the big selling points for me. I know what needs to happen. I need to add fluid so there is a smaller air gap to the adjusters. There never was enough fluid installed to have that set correctly.
Motion Pro claims that this is a proprietary fluid and has to be used. Has anyone tried a different fluid, like motor oil or another antifreeze? I never liked the word proprietary and always attempt to get around it...
Thanx.....
