1) The measuring ranges which are thus marked are to be used exclusively with clean and non-corrosive gases.
2) For measuring instruments with a max. measuring range of up to 2 bar, the working order in the vacuum measuring range is limited to -350 mbar.
(The measuring ranges -1 ... +1 bar and -1 ... +2 bar are excluded.)
3) CPGLog data logger evaluation software is required for the utiisation of the logger functionality.
