Clear total
The value for total can be re-initialized. To do so, press CLEAR twice. After pressing CLEAR
once, the flashing text "PUSH CLEAR" is displayed. To avoid re-initialization at this stage, press
another key than CLEAR or wait for 20 seconds.
Re-initialization of total DOES NOT influence the accumulated total.
•
Display accumulated total
When the SELECT-key is pressed, total and accumulated total are displayed. The accumulated
total cannot be re-initialized. The value will count up to 99,999,999,999. The unit and number of
decimals are displayed according to the configuration settings for total.

Programming the flow rate alarm values
This function might not be accessible due to a configuration setting.
When the SELECT-key is pressed a few times, flow rate alarm values are displayed:
Fig. 4: Example of display information during programming minimum flow rate.
•
Flow rate alarm
When the actual flow rate is outside the allowed range, an alarm message will be displayed
indicating the type of alarm: "LO RATE", "HI RATE".
The alarm is terminated automatically as soon as the flow rate is within its range again.
•
Low-battery alarm
When the battery voltage drops, it must be replaced. At first "low-battery" will flash, but as soon
as it is displayed continuously, the battery MUST be replaced shortly after!
The remaining lifetime after the first moment of indication is generally several days up to some
weeks. See paragraph 6.3 for further information on battery replacement.
