3.3.4 EXPLANATION OF SETUP-MENU 3 - POWER MANAGEMENT
When used with the internal battery option, the user can expect reliable measurement over a long
period of time. The F011-P has several smart power management functions to extend the battery life
time significantly. Two of these functions are available.
SETUP FUNCTIONS AND VARIABLES
3 POWER MANAGEMENT
3.1 LCD NEW
The calculation of the display-information influences the power
consumption significantly. When the application does not require a
fast display update, it is
strongly advised to select a slow refresh
rate. Please understand that NO information will be lost; every pulse
will be counted and the output signal will be generated in the normal
way. The following can be selected:
Fast - 1 sec - 3 sec - 15 sec - 30 sec - off.
Example battery life-time with a coil pick-up:
•
1kHz pulse and FAST update: about 2 years.
•
1kHz pulse and 1 sec update: about 5 years.
After a button has been pressed by the operator - the display refresh
rate will always switch to FAST for 30 seconds. When "OFF" is
selected, the display will be switched off after 30 seconds and will be
switched on as soon as a button has been pressed.
3.2 BATTERY MODE
The F011-P has two modes: operational or shelf.
After "shelf" has been selected, the F011-P can be stored for several
years; it will not process the sensor signal; the display is switched off
but all settings and totals are stored. In this mode, power consumption
is extremely low.
To wake up the F011-P again, press the SELECT/

key twice.
3.3.5 EXPLANATION OF SETUP-MENU 4 - FLOWMETER
The F011-P is able to handle several types of input signal. The type of flowmeter pickup / signal is
selected with SETUP 4.1. Read also paragraph 4.6.1 Terminals 1-3: Flowmeter input.
