. A more accurate K-Factor (more decimals, as set in decimals
K-Factor) allows for a more accurate operation of the system.
DECIMALS K-FACTOR
25
This setting is used to set the amount of digits behind the decimal point for the
K-Factor.
CALCULATION
26 The flow rate is calculated by measuring the time between a number of
pulses, for example 10 pulses. The more pulses the more accurate the
flow rate will be. The maximum value is 255 pulses.
This setting does influence
the update interval for the flow rate and
thus, indirectly the update interval of the analog output..
(maximum
update 10 times a second). If the output response is too slow, decrease
the number of pulses. For low frequency applications (< 10Hz): do not
program more than 10 pulses, else the update time will be very slow.
For high frequency applications (> 1kHz): do program 50 or more pulses.
CUT-OFF
27 This setting is used to set the threshold for a minimum flow. If during this
time less than XXX-pulses are generated (refer to Calculation), the flow
rate will be shown as zero. The cut-off has to be entered in seconds.
LOW FLOW RATE
ALARM
28 This setting is used to activate the related alarm condition and to set the
threshold value for a this flow alarm. The setting 0.0 disables this alarm.
HIGH FLOW RATE
ALARM
29 This setting is used to activate the related alarm condition and to set the
threshold value for a this flow alarm. The setting 0.0 disables this alarm.
DELAY TIME ALARM
2A This setting is used to set a delay time for the related alarm. When the
alarm condition is still valid after the delay time, an alarm is given.
3.1.3. EXPLANATION OF SETUP MENU 3 - DISPLAY
LIGHT
33 The backlight brightness can be adjusted from 0% (off) to 100% (full
brightness) in steps of 20%.
When the F133-P is only loop powered, the backlight is disabled. An
external power supply is required to supply the backlight.
BL ALARM
34
This setting is used to set the behavior of the backlight (bl) during an alarm
condition.
3.1.4. EXPLANATION OF SETUP MENU 4 - 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 F113-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.
BATTERY MODE
42
The F113-P has two modes: operational or shelf.
After "shelf" has been selected, the F113-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 F113-p again, press the select/

key two times.
