POWER MANAGEMENT
5.1
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 - off.
Example battery life-time:
•
FAST update: about 3 years.
•
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.
5.2
BATTERY MODE
The F013-A has two modes: operational or shelf. After "shelf" has
been selected, the F013-A 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 F013-A again, press the SELECT/
key twice.
