MENU 8 - POWER MANAGEMENT

When used with the internal battery option (type PB/PC), the user can expect reliable measurement
over a long period of time. The F114-P has several smart power management functions to extend
the battery life time significantly. Two of these functions can be set.

Enables the setting of alarm levels in Operator mode.
The backlight brightness can be adjusted from 0% (off) to 100% (full
brightness) in steps of 20%.
Sets the backlight functionality during alarm condition.
The calculation of the display-information influences the power
consumption significantly. When the application does not require a fast
display refresh rate, 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 signals will be generated in the normal way.
At a key press, the display refresh rate will switch to FAST for 30 seconds.
When 'OFF' is selected, the display goes off after 30 seconds after the last
key press. The display temporarily comes on after a key press.
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.
The F114-P has two modes: operational or shelf.
After "shelf" has been selected, the F114-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 F114-P again, press the SELECT/▲ key two times.
With this setting the type of output of flowmeter A is selected. The settings
with LP (low-pass) filter are used to apply a build-in noise reduction.
Selections "active pulse" offer a detection level of 50% of the supply
voltage.
