How to change from point-to-point to multidrop mode
• Enter supervisor mode.
• Go to Advanced Setup > Output 1 (HART) > HART Address
Advanced Setup > Output 1 (HART) > HART Address Advanced Setup > Output 1 (HART) > HART Address Advanced Setup > Output 1 (HART) > HART Address.
• Enter a value between 1 and 15 and push [^ ^ ^ ^] to confirm (see the caution below).
• Push the Escape buttons ([>>>>] + [    ]) until you get the save/cancel screen.
• Select save.
• Push [^

6.4.3 Linearisation
You can use the Linearisation Table Linearisation Table Linearisation Table Linearisation Table (menu item C.1.22) to make sure that readings are
consistently accurate.
• Go to Supervisor > Advanced Setup > Installation Setup > Linearisation Table Supervisor > Advanced Setup > Installation Setup > Linearisation Table Supervisor > Advanced Setup > Installation Setup > Linearisation Table Supervisor > Advanced Setup > Installation Setup > Linearisation Table.
• Type in the number of reference points (up to 50 points). Push [^ ^ ^ ^].
i This shows the linearisation table with default values.
• Push [>>>>] to type in new data. The device reading is given on the second line Device distance Device distance Device distance Device distance.
• Fill the tank to any given level.
• Make an appropriate reference measurement. Type this data on the line Real distance
Real distance Real distance Real distance.
• Repeat these steps until all the cells in the linearisation table are completed.
• Push [^
^ ^ ^].
• Push [>>>>] and [    ] (Esc) at the same time to exit to the "save settings" window.
• Select Save Save Save Save and push [^ ^ ^ ^].
i The device will go back to operator mode.
6.4.4 Distance measurement
The device displays distance measurements when an output is set to distance.
Menu items related to distance measurement are:
• Output Function (C.3.1 or C.4.1)
• Tank Height (C.1.2)
CAUTION!
Make sure that the address for this device is different from others in the multidrop network.
