WIKA DI15 - Manual (Page 14)

Operating Instructions Digital Indicator DI15
V1.3 • 02/2011 - 14 -
- When pressing button 1 again, the display shows “outP“. (output)
For configuring the outputs of the DI15, please follow the instructions shown in chapter 4.8.
For setting the offset and for setting the slope-adjustment, please follow the instructions given in chapter 6.
4.4. Measuring of frequency (TTL, switching-contact)
This chapter describes how to configure the device for measuring frequency.
This instruction requires that you selected “FrEq“ as your desired input type like it is explained in chapter 4.1.
The device has to display “InP“.
- When pressing button 1 the display will show “SEnS“.
- Use button 2 or button 3 (middle resp. right button) to select the desired input signal.
Display Input signal Note
ttL TTL-signal
nPn Switching contact, NPN
For direct connection of a passive switching
contact (e.g. push button, relay) resp. Trans-
mitter 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.
- 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 resp.
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 resp.
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.
