A Turn down 4 mA
B Turn down 20 mA
Subfunction: "4 mA threshold" - for Current span = 4 to 20 mA
It is possible to switch on the 4 mA threshold in this subfunction. The 4 mA threshold
means that the current never is below,4 mA even if the measured value is negative.
Options:
• Off
The threshold is switched off. Currents under 4 mA can occur.
• On
The threshold is switched on. The current is never below 4 mA.

7.6.2 Submenu: "HART setting"
Function: "HART settings"
Subfunction: "HART address"
In this subfunction, specify the HART communication address for the device.
Possible values:
• for standard operation: 0
• for multidrop operation: 1 - 15
In multidrop operation, the output current is 4 mA as standard. However, it can be
changed in the "mA value" function.
Subfunction: "No. of preambles"
In this subfunction, specify the number of preambles for the HART protocol. Increase the
value if there are communication problems on the lines.
Subfunction: "Short TAG HART"
Here, you can enter the TAG name for HART communication in the device.
