5.5.6 Setting the pulse repetition frequency (on the 3102/3105)
Screen display: Prf
Default: 1.0
The rate of pulses transmitted is set to a factory default value of once-per-second.
The pulse repetition frequency may be changed to overcome cross talk problems if more than
one ultrasonic transmitter is mounted in the same tank.
The transmitter may be set to transmit faster or slower at selectable repetition rates between
0.5 and 2.0 times per second.
Note
This menu option is in the engineering menu “Eng”. See “Accessing the engineering menu (on
the 3102/3105)” on page 62 or see Figure C-5 on page 106 for a map of the menu structure.
To change the pulse repetition frequency:
1. After entering the “Eng” menu (see the note above), press the green button
repeatedly until “Prf” is indicated.
2. Press the blue button
to enter the pulse frequency menu.
The display indicates the present frequency value.
3. If this pulse frequency is correct, press the red button
and then press the green
button
to get to the next menu option. Otherwise, continue with step (4).
4. Press the blue button
to start the editing mode. The pulse repetition frequency
flashes to indicate it can be edited.
5. Press the green button
repeatedly to scroll through the available options (0.5 to 2.0).
6. Press the blue button
to confirm the new setting. (The flashing stops).
7. Press the red button
to save the new setting if it is correct, or press the blue button
to not save. Afterwards, depending on the button pressed, either the “Prf” menu or the
next menu appears.
Note
There is an increased risk of a Lost Echo condition if this parameter value is set to too high.
