Two settings are available: Disabled or Enabled. By default, the
Temperature Alarm is non-latching. This means that the Alarm Action is
indicated only if the monitored Temperature reading exceeds the user-
specified conditions.

The DPM provides the user with two independent Programmable Flow
Totalizers. The total volume (mass) of the flowing fluid is calculated by
integrating the actual instantaneous fluid mass flow rate with respect to time.
Totalizer reading values are stored in the EEPROM and saved every second.
In the case of power interruption, the last saved Totalizer value will be loaded at
the next power on cycle, so the Totalizer reading will not be lost. Use the
“Totalizer Menu” to navigate to the “Totalizer #1” or "Totalizer #2" menu options.
The following settings are available for Totalizer #1 and Totalizer #2 (see
Figure

increments of 0.1%, from 0 - 100% FS.
c) Totalizer Action Volume (Numerical entry)
This option allows the user to activate a preset required action when the
Totalizer reaches a preset volume. Totalizer Action Volume value must be
entered in currently active volume- / mass-based engineering units. A
Totalizer Action Event becomes true when the Totalizer reading is more
than or equal to the preset "Totalizer Action Volume”. If the Totalizer feature
NOTE: Before enabling the Totalizer, ensure that all Totalizer settings are
configured properly. Totalizer Start values must be entered in the currently
active Volumetric or Mass flow engineering unit. The Totalizer will not
totalize until the Process Flow Rate becomes equal to or greater than the
Totalizer Start value. Totalizer Event values must also be entered in
currently active volume- or mass-based engineering units. If the Totalizer
Event (action) is not required at a preset total volume feature, set the
Totalizer Event value to zero (which is the default setting).
