DECIMALS
This setting determines for engine speed the number of digits
following the decimal point. The following can be selected:
00000 - 1111.1
2.2
K-FACTOR
With the K-factor, the Tachometer pulse signals are converted to
an engine speed (RPM).
The K-factor is based on the number of pulses generated by the
Tachometer per RPM. The more accurate the K-factor, the more
accurate the functioning of the system will be.
2.3
DECIMALS K-FACTOR
This setting determines the number of decimals for the K-factor
(SETUP 2.2). The following can be selected:
0 - 1 - 2 - 3 - 4 - 5 - 6
Please note that this SETUP - influences the accuracy of the K-
factor indirectly. This setting has NO influence on the displayed
number of digits for "engine speed" (SETUP 2.1)!

Page 15
FW-F093-P-M_v0404_01_EN.docx
2.4
CALCULATION
The engine speed is calculated by measuring the time between a
number of pulses, for example 10 pulses. The more pulses the
more accurate the engine speed will be. The maximum value is
255 pulses.
This setting does influence the update time for the analog output
directly (maximum update 10 times a second). If the output
response is too slow, decrease the number of pulses.
The lower the number of pulses, the higher the power
consumption of the unit will be (important for battery powered
applications).
For low frequency applications (below 10Hz): do not program
more than 10 pulses else the update time will be very slow.
For high frequency application (above 1kHz) do program a value
of 100 or more pulses.
2.5
CUT-OFF
With this setting, you determine a minimum RPM requirement
threshold, if during this time less than XXX-pulses (SETUP 2.4)
are generated, the engine speed will be displayed as zero.
The cut-off time has to be entered in seconds - maximum time is
999 seconds (about 15 minutes).

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 - 30 sec - off.
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.
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 F093-P has two modes: operational or shelf.
After "shelf" has been selected, the F093-P can be stored for several
years; it will not process the sensor signal; the display is switched off
but all settings and running hours are stored. In this mode, power
consumption is extremely low.
To wake up the F093-P again, press the SELECT/key twice.
