active,
(frequency range limit)
The measuring range is exactly bounded by
the selected frequency-measuring-range-limit.
When exceeding or shortfalling of the limit the
device will display the lower or upper display-
range-limit.
[e.g. humidity: when shortfalling or exceeding,
the device will display 0% or 100%]
Hint:
When exceeding the maximum range limit (10kHz) independently from the limit setting an error message will
be displayed (“Err.1“).
-
Press button 1 to validate your selection. The display shows “
Li
“ again.
-
When pressing button 1 again, the display will show “
FiLt
“ (Filter
= digital filter
).
-
Use button 2 or button 3 to select the desired filter value [in sec.].
Usable values: 0.01 ... 2.00 sec.
Explanation: this digital filter is a digital replica of a low pass filter.
-
Press button 1 to validate your selection. The display shows “
FiLt
“ again.
-
When pressing button 1 again, the display shows “
InP
“ ('INPUT') again.
Now your device is adjusted to your input signal.
-
Press now button 4 to exit the input configuration menu.
4.5. Measuring of rotation speed (TTL, switching-contact)
This chapter describes how to configure the device for measuring rotation speed.
This instruction demands that you selected “
rPn
“ as your desired input type like it is explained in chapter 4.1.
The device has to display “
InP
“.
-
When pressing button 1 the device will display “
SEnS
“.
-
Use button 2 or button 3 to select the desired input signal.

Notes
ttL
TTL-signal
nPn
Switching contact, NPN
For direct connection of a passive switching
contact (e.g. push button, relay) or transmitter
with NPN output.
A pull-up-resistor is internally connected.
Hint: when using push-buttons or relays, they must
be bounce-free!
PnP
Switching contact, PNP
For direct connection of a transmitter with
PNP output.
A pull-down-resistor is internally connected.
Hint:
For the connection of a frequency-transmitter, please follow the instructions given in chapter 3.3.6
When connecting a switching-contact-transmitter with increased frequency range (= with external circuitry)
you have to select TTL as your desired input signal.
-
Press button 1 to validate your selected input signal. The display shows “
SEnS
“ again.
-
When pressing button 1 again, the display will show “
diu
“ (divisor).
-
Use button 2 or 3 to select your desired divisor.
Set the divisor to the pulses per rotation the transmitter supplies.
-
Press button 1 to validate your selection. The display shows “
diu
“ again.
-
When pressing button 1 again, the display will show “
dP
“ (decimal point).
-
Use button 2 or button 3 to select the desired decimal point position.
Use the decimal point position to change the resolution of your measurement. The more the decimal
point position is on the left, the finer the resolution will become. Please note that you lower the maximum
value that can be displayed, either.
