When your LLT100 is on a network, you can set multiple
connection parameters from the Communication menu.
13.6.1
Editing the instrument address
To modify the instrument address:
1. From the Communication menu, select Device Address.
2. Edit the address and press OK.
13.6.2 Selecting the loop current mode
Should you connect multiple LLT100 instruments in a loop
linked to the same power supply (a.k.a. multi-drop mode), you
must set the loop current mode to a fixed value and not to the
4–20 mA mode.
