With this key the data of VEGADIS 174 can be en-
quired. By pushing the key, the display indicates the
adjusted address. If you keep the key pushed, the
address and the DIS-number (channel) of VEGADIS
are alternately displayed.
Rotating switch VEGAMET ADDR. (1)
With the 16-step rotating switch (VEGAMET ADDR.)
you select the respective signal conditioning instru-
ment. The address number must be determined on the
respective signal conditioning instrument. VEGADIS
174 reads the data of the signal conditioning instru-
ment, to which it is addressed.
Rotating switch DIS No. (2)
With the 10-step rotating switch (DIS No.) VEGADIS is
set to the channel (DIS-number) of the respective
signal conditioning instrument. The DIS-number can
be selected on VEGAMET. If a processing system
VEGALOG is connected, the DIS-number must not be
connected. The rotating switch (2) is in any case
without function.
