7.4.2 General settings
Proceed in accordance with the description in the MESSKO®MSET param-
eterization software operating instructions in order to adjust the following
listed settings where necessary.
Measurement interval setting
The measurement interval is the time between two measurements (in hours).
The shortest measurement interval is three hours.
Measurement interval
Standard value 6hours
Maximum value 24hours
Minimum value 3hours
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 68]).
Time stamp
Make a note of the time stamp of the oil sample extraction for the laboratory.
This is needed for the water content (H2O in ppm) calibration. The time
stamp is updated with service code 1: sample extraction.
Once the sample has been analyzed by a laboratory, the time stamp must
be entered together with the analysis results for adjustment via the
MESSKO® MSET parameterization software. To do so, use the service
code 33.
