5.4 Measuring of frequency (TTL, switching-contact)
This chapter describes how to configure the device for measuring frequency.
This instruction demands that you selected “FrEq“ as your desired input type like it is explained in chapter 5.1.
The device has to display “InP“.
- When pressing button 1 the display will show “SEnS“.
- Use button 2 or button 3 (middle or right button) 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.
When connecting a switching-contact-transmitter with increased frequency range (= with external
circuitry) you have to select TTL as your desired input signal.
- Validate your selected input signal by pressing button 1. The display shows “SEnS“ again.
- When pressing button 1 again, the display will show “Fr.Lo“ (frequency low = lower frequency range limit).
- Use button 2 and button 3 to select the lowest frequency that may occur when measuring.
- Press button 1 to validate your selection. The display shows “Fr.Lo“ again.
- When pressing button 1 again, the display will show “Fr.Hi“ (frequency high = upper frequency range limit).
- Use button 2 and button 3 to select the highest frequency that may occur when measuring.
- Press button 1 to validate your selection. The display shows “Fr.Hi“ again.
- When pressing button 1 again, the display will show “dP“ (decimal point).
- Use button 2 and button 3 to select the desired decimal point position.
- Press button 1 to validate your selection. The display shows “dP“ again.
- When pressing button 1 again, the display will show “di.Lo“ (display low = display at lower frequency range limit).
- Set the value the device shall display at the lower frequency range limit by pressing button 2 or button 3.
- Press button 1 to validate your selection. The display shows “di.Lo“ again.
- When pressing button 1 again, the display will show “di.Hi“ (display high = display at upper frequency range limit).
- Set the value the device shall display at the upper frequency range limit by pressing button 2 or button 3.
- Press button 1 to validate your selection. The display shows “di.Hi“ again.
- When pressing button 1 again, the display will show “Li“ (limit = measuring range limitation).
- Use button 2 and button 3 to select the desired measuring range limitation.

Active, (displays error)
The measuring range is exactly bounded by
the selected frequency-measuring-range-limit.
When exceeding or shortfalling of the limit the
device will display an error message.
