6 Instrument modification
6.1 Exchange of adjustment mod-
ules
The modular construction of VEGABAR allows
retrofitting, interchange or removal of the
adjustment and display modules. Data previ-
ously saved (e.g. adjustment values) are not
stored in the adjustment module but in an
EEPROM of the electronics module and
therefore readjustment is not necessary. The
connection of the modules is made via a 4-
pole plug connection.
Exchange of the adjustment module

supply

nection of the display module
• Remove the two screws of the adjustment
module
• Remove adjustment module and pull out

justment module into the plug-in socket of

essary, also the cable from the display
