Clearing the current gauge volume calibration table data
1.
Go to fct. 1.7.3 DELETE TAB.
2. Press “right” to enter the data set field. This will read “SURE No”.
3. Press “up” to select “SURE Yes”.
4. Press “enter” to confirm clearing the “strapping table”.
5. Go to fct. 1.7.2 INPUT TAB. to enter new values into an empty table.
3.4.4 Network Configuration – digital outputs and gauge identification : RS 485, multi-drop...
Example procedure 6:
• turn off analog current output to read a digital signal *, **
• give each gauge an address and device number

6 Enter function. A number will be
displayed (default value: 000- no
network) → 000
7 Change address to 001. →,→,↑ 001
8 Enter to confirm and exit to function.
Go to fct 1.4.4 to give the gauge a
device number (displayed on a remote

9 Enter data set field. (default value:
00000.001). A 9-keystroke
alphanumerical code may be entered
using “up” to scroll through the choices
and “right” to change digit → 00000.001

*Ignore steps 2, 3 and 4 for HART® outputs. Leave the analogue output “on”.
**Use local display interface only to configure each BM 100 A meter for network integration.
Communication Rate
Use fct. 1.6.1 BAUD RATE to optimise communication with the remote work station when using
RS485 interface. HART/ SMART networks are set at 1200 baud.
