4.4 Adjustment with HART ® handheld
The VEGAFLEX sensors can be set up with
any HART
® handheld. A special DDD (Data
Device Description) is not necessary. Just
connect the HART
® handheld to the signal
cable after having connected the sensor to
power supply.
Note
If the resistance of the signal current circuit is
less than 200
Ω
, a resistor of 250 … 350
Ω
must be connected to the signal/connection
cable during adjustment. Simply loop the
resistor into the sensor connection cable
(see figure).
