VEGA VEGADIS 12 - Manual (Page 17)

l
The requested function is selected with the rotary switches
l With the [+] and [-] keys the signal current or the
integration time is set or the indication is scaled
l
The respective rotary switch is finally set to position
"OPERATE"
The set values are transmitted to the EEPROM memory and
remain there even in case of voltage loss.
Proceed as follows for adjustment with VEGADIS 12:
1 Open housing cover
2 Connect hand multimeter to terminals 10 and 12
3 Meas. range begin: Set rotary switch to "zero"
4 Empty the vessel or reduce process pressure
5 Set a current of 4 mA with the [+] and [-] keys
6 Meas. range end: Set rotary switch to "span"
7 Fill the vessel or increase process pressure
8 Set a current of 20 mA with the [+] and [-] keys
9 Operation: Set rotary switch to "OPERATE"
10 Close the housing cover
The adjustment data are effective, the output current 4 … 20 mA
corresponds to the actual level or pressure.
Information:
The corresponding current values must be calculated and set
respectively for adjustment with part fillings or emptyings.
Example: For a part emptying of 25 %, a current of 4 mA +
4 mA = 8 mA must be set, for a part filling of 75 %, a current of
4 mA + 12 mA = 16 mA. VEGADIS 12 then calculates the
values for full and empty.
Proceed as follows for the adjustment of the integration time
with VEGADIS 12:
1 Open housing cover
2 Set rotary switch to "ti"
3 Make sure that the integration time is set to 0 sec by
pressing the [-] key 10 times.
4 For every 1 sec. requested integration time, push the [+]
key once.
