H2O reference setting
The analysis results of the MESSKO® oil laboratory or an equivalent labora-
tory can be entered here in order to make a comparison between the water
content (H2O in ppm) of the MSENSE® DGA 2/3 analysis and that of the
laboratory. A field comparison for the gases H2 and CO is performed in the
service area of the MSET software (see chapter Maintenance [►Section 10,
Page 67]).
