Instrument modification
6 Instrument modification
6.1 Interchanging adjustment
modules
The modular construction of VEGABAR allows
retrofitting, interchange or removal of adjust-
ment modules and the indicating module.
Retrofitting may be necessary e.g. when a
VEGABAR with factory settings should be
adapted to modified measurement condi-
tions. Data already saved (e.g. adjustment
values) are not saved in the adjustment mod-
ule but in an EEPROM of the oscillator and re-
adjustment is therefore not necessary.
The connection of the modules is made:
- on the adjustment module via a 4-pole plug
connection
- on the indicating module via screw termi-
nals.
Exchange of the adjustment module
Removal of the adjustment module
1
Separate VEGABAR from the power
supply
2 Loosen the screws on the cover of
VEGABAR or VEGADIS 10
3 Loosen connection cable from the termi-
nals
4 Loosen screws of the adjustment cover
5 Remove adjustment cover and plug con-
nection
Insertion of an adjustment module
6
Plug the connection of the new adjust-
ment cover to the plug-in socket of the
oscillator
7 Fasten new adjustment cover
8 Fasten connection cables to terminals
9 Close cover of VEGABAR or VEGADIS 10
10 Connect VEGABAR to power supply
Retrofitting of an indicating module
1 Separate VEGABAR from power supply
2 Loosen screws on cover of VEGABAR or
VEGADIS 10
3 Remove cover
4 Connect indicating module to the screw
terminals via the four lines (note “3.3
Connection plan“)
Note:
Step 4 is facilitated when the indicating mod-
ule is temporarily (carefully) mounted with two
screws.
5 Place indicating module in the correct
position on VEGABAR or VEGADIS 10
6 Tighten screws of the cover
7 Connect VEGABAR to power supply
