To enter results from laboratory analyses, the date of the analysis should first be entered in the
“Sample date” field. The daily average gas concentrations of the MSENSE® DGA 9 are then deter-
mined and displayed in the “MSENSE® DGA 9 value” fields. After the results of the laboratory analy-
sis have been entered in the “Laboratory value” fields for H

, the key is rendered active. After pressing the key, the new correction factors are
calculated. Following a short calculation time, as indicated by the hourglass symbol, the following
message appears on the LCD display: “Determination of DGA adjustment successful.”
The new values are saved and activated by leaving the menu using the “Save and exit” key .
The new correction factors are now applied to the following measured values.
6.10.2 Settings – analogue outputs
This MSENSE® DGA 9 device has 10 analogue current outputs, which can be operated with 0 ... 20
mA or 4 ... 20 mA. These can be used as outputs for the gas-in-oil concentration, oil moisture, temper-
atures and for all additional sensors.
The standard factory setting / assignment is as follows:
Output #1: Mode: 4 ... 20 mA Sensor: H

In the menu, test currents can be set which override the current values. These are used for checking
the installation. When exiting the menu, the current values are then re-issued.
