Totalizer Rollover Functions
Your flow totalizer has been configured to report a maximum of 7 digits. By
default, the placement of the decimal is the same as the live flow rate. The
totalizer can be configured at the time of order for the following behaviors.
• Rollover
(default)
:
Totalizer resumes
counting from 0
as soon as the
maximum count has
been reached.
• Freeze:
Totalizer
stops counting at
max count, until it
is reset manually.
• Error:
Displays
OVR
status message when
maximum count
has been reached;
compatible with
Rollover and Freeze.
The time counter has a maximum value of 9999:59:59 (h:m:s) (416 days, 16
hours). If flow is still being totalized at that point, the timer freezes, regardless
of totalized flow settings.
Option: Collecting Totalized Flow Data
Your flow meter may have been purchased with an optional flow totalizer.
This displays the total amount of mass or volume that has flowed through
the instrument since its last reset, like a gasoline pump. You can access
the totalizer screen by pressing
TOTAL/MENU
on the Main Display.
