Information:
The metal parts of the instrument (antenna, transmitter, concentric
tube, etc.) are conductive connected with the inner and outer ground
terminal on the housing. This connection exists either directly metallic
or with instruments with external electronics via the screen of the
special connection cable. You can find specifications to the potential
connections within the instrument in chapter "Technical data".

5.3 Switch on phase

After connecting VEGABAR 12 to power supply or after a voltage
recurrence, the instrument carries out a self-check:
Internal check of the electronics
l
4 ... 20 mA output jumps to the failure signal 3.6 mA
l
Then VEGABAR 12 delivers a current of 4 ... 20 mA to the cable. The
value corresponds to the actual level as well as to settings already
carried out, e.g. the factory setting.
