This setting can be set to display differential total or rate.
• When 'total' is selected, total is shown with the large digits together
with flow rate with the smaller digits. When SELECT is pressed, the
accumulated total is shown temporarily.
• When 'rate' is selected, only flow rate will be shown with the large
digits together with its measuring unit. When SELECT is pressed, the
total and the accumulated total are shown temporarily.
DISABLE Only differential total can be shown in Operator mode
ENABLE Differential and accumulated totals for flow A and B can be
shown in Operator mode.
The backlight brightness can be adjusted from 0% (off) to 100% (full
brightness) in steps of 20%.
When the F115-P is only loop powered, the backlight is disabled. An
external power supply is required to supply the backlight.
3.3.7 MENU 6 - 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 F115-P has several smart power management functions to extend
the battery life time significantly. Two of these functions can be set.
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 F115-P has two modes: operational or shelf.
After "shelf" has been selected, the F115-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 F115-P again, press the SELECT/ key two times.
With this setting the type of flowmeter A output 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.
