Display flowrate / total or flowrate
This is the main display information of the F113-A. After selecting any other information, it will
always return to this main display automatically. Total is displayed on the upper-line of the
display and flowrate on the bottom line.It is possible to display flowrate only with the large
17mm digits; in this instance press the SELECT-key to read the total.
When "-------" is shown, then the flowrate value is too high to be displayed. The arrows 
indicate the flowrate trend.

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 reset at this stage, press
another key than CLEAR or wait for 20 seconds.
Reset 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 flowrate alarm values
Note: This function might not be immediately accessible due to a configuration setting.
When the SELECT-key is pressed a few times, following flowrate alarm values are displayed:

low-low flowrate alarm (lolo): enter here 20 L/min for example,

low flowrate alarm (lo) : enter here 40 L/min for example,

high flowrate alarm (hi): enter here 200 L/min for example,

high-high flowrate alarm (hihi): enter here 250 L/min for example.
To change the alarm value, the following procedure must be executed:
1) Press PROG: the word "PROGRAM" will flash or a password will be requested,
Use  to select the digits and  to increase that value,
2)
3) Confirm the new alarm value by pressing ENTER.
Fig. 4: Example of display information during programming minimum flowrate.
When data is altered but ENTER has not been pressed yet, then the alteration can still be
cancelled by waiting for 20 seconds or by pressing ENTER during three seconds: the former
value will be reinstated.

Flowrate alarm
When the actual flowrate is outside the allowed range, an alarm message will be displayed
indicating the type of alarm: "LO RATE", "HI RATE", "LO-LO RATE" or "HI-HI RATE".
The alarm is terminated automatically as soon as the flowrate is within its range again.

Low-battery alarm
During operation the battery voltage drops. When the battery voltage becomes too low, the
battery indicator comes on to show that the operation and indication become less reliable.
When the battery indicator is on, install a fresh and new battery (as soon as possible) to keep
a reliable operation and indication.
