will be displayed on the second line of the LCD (#241 is for example only, actual
number may be different).
b) Event Log Configuration
If Event Log configured to “Loop Off” mode, the Event Log file will be locked
(disabled) when last event with index 511 is recorder. If Event Log configured to
“Loop On” mode, when last index (511) is reached, the firmware “wraps around”
Event Log index back to 0 and new records will overwrite old Events records.

with LCD bit code 9, #13 with LCD bit code D, #15 with LCD bit code F are masked
with asterisk. In order to change Log event mask settings user should press Enter
button. The flashing cursor will appear on the left of the LCD screen (on the 0
event position). Use Dn [Cursor] button to move to desired event code. Use Up
button to change mask status (asterisk represent masked event). Use Enter but-
ton to accept and save new Event Log mask settings in flow meter’s non volatile
memory.
d) Clear Event Log
In order to reset (clear) Event Log File press Ent button. Following screen will
appear just for two seconds.
NOTE: System Events (see table 5.2) can not be masked therefore will
be always recorded in to the Event Log File.
