•
The total flow is displayed in milliliter [ml] with three digits when the value is below one liter (<1 l).
–
When the value is ≥ 1 l, the unit is changed to liter [l]. In this case, the maximum displayed total flow is
999.9 liter, whereas the digit stating the ml-value is the one after the full stop.
–
When the sum exceeds a value of 999.9 liters, the lower left corner shows 1 m
3
and the totalizer will
continue to operate.
–
The maximum digits for the m
3
counter is three digits, which corresponds to a maximum of 999 m
3
.
•
The totalizer has two limits. Either a totalizing time of 999:59:59 hours (approximately six weeks) or a
totalized flow of 999 m3 or 999.9 l.
–
Whenever one of these limits is reached, the totalizer is stopped and the string "OVR" (=Overrun") is
shown on the display.
–
The values for Totalizing Time and Total Flow are held and shown on the display until the user resets the
totalizer, turns off the power, or disconnects the sensor.
•
When entering the totalizer screen, the screen shows:
–
"Hold", when the totalizer is running
–
"Run", when the totalizer has not been started, yet, or when the totalizer was stopped.
By pressing the enter button, the user is able to start/stop the totalizer. Entering other menus of the
device while the totalizer is running will not have an effect on the totalizer.
•
When the totalizer is running and the enter button is pressed, the totalizer is stopped. The display will
show the value for the total flow at this point and indicate "Run" status.
•
Pressing the enter button again will resume the totalizing process, starting with the Totalizing Time and
Total Flow before stopping. Additionally, the Totalizing Time value will stop flashing.
•
While in the totalizer menu, the totalizer is reset by pressing the Zero/Reset button. The resetting can
be performed while the totalizer is in the Hold or Run status. When the totalizer is reset during run, it
continues working, starting with a zero value.
•
In case of insufficient coupling (<50 %) during the run of the totalizer, an exclamation
mark is shown next to the string "Total Flow" (Indication for the user).
•
While the coupling is insufficient, the Totalizing Time is stopped and the Total Flow value
is not changed (no further summation).
•
If the coupling increases back to ≥50 % (e.g. after a bubble has passed), the totalizing
process resumes with the values of before the drop in coupling occurred. The exclamation
mark will stay on the screen until zero is pressed.
•
If a sensor is disconnected during the totalizer run, the data is deleted.
•
Please note
that the totalizer information is not transferred through the RS-232 interface.
