Setup

4.4 Setup with HART

handheld

Sensors with electronics versions I, K and L

can be set up with the HART

handheld. A

special DD (Data Device Description) is not

necessary. Just connect the HART

handheld

to the sensor signal cable after you have

connected the sensor to supply voltage.

Note:

If the resistance of the voltage supply is less

than 250 Ω, a resistor must be looped into the

signal/connection cable during adjustment.

The digital adjustment and communication

signals would otherwise be short-circuited

through insufficient resistance of e.g. the

supply voltage source or the processing

system. Simply connect the adjustment resis-

tor in parallel to the connection socket of the

HART

handheld.
