SW/Alarm min The alarm current is defined by the setting in
the operating menu.
("Setup" -> "Extended setup" ->
"Curr. output" -> "Output fail mode")
The alarm current is 3.6 mA regardless of
the setting in the operating menu.
The following switches only for Deltabar M:

The output characteristics is defined by the
setting in the operating menu.
• "Setup" -> "Measuring mode"
• "Setup" -> "Extended Setup" -> "Current
output" -> "Linear/Sqroot"
The measuring mode is "flow" and the
output characterisitcs is "Square root"
regardless of the settings in the operating
menu.
