EXPLANATION OF SETUP-MENU 5 - POWER MANAGEMENT

When used with the internal battery option, the user can expect reliable measurement over a long
period of time. The F073-T has several smart power management functions to extend the battery life
time significantly. Two of these functions are available.
SETUP FUNCTIONS AND VARIABLES

5.1 LCD NEW
5.2 BATTERY MODE
The small 8mm digits can be set to display height, percentage or
nothing (off).
This function determines if the level alarm values can be set at both
Operator level and SETUP-level or SETUP-level only.
If SETUP has been selected, the alarm values are still visible for the
Operator but cannot be changed.
The functions below will only affect the optional LED-backlight.
If a LED backlight has been supplied, it can be turned on or off.
In case the F073-T generates a level alarm, the backlight can be set
to change to red. Following selections are available:
OFF: during level alarm display is according to SETUP 4.3
ON: during level alarm the color is red.
FLASH: during level alarm the color flashes red.
The backlight brightness is adjustable. The following can be selected:
1 – 5 (where 1 is minimum and 5 is maximum brightness)
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:
•
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.
The F073-T has two modes: operational or shelf. After "shelf" has
been selected, the F073-T 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 F073-T again, press the SELECT/ key twice.
