9.1.8.1 Setting up the Measurement Mode
The PT878GC can take measurements in four different ways:
Skan is a low resolution technique for locating the acoustic signal and for high velocity measurements. It is more
robust in a noisy environment than the Measure technique.
Measure is a more precise technique best used for low velocity measurements. You can choose from Skan/Measure
Count (the default technique) or Skan/Measure Integrate (the traditional Skan/Measure mode). A variation, the
Skan/Correlation mode, is used primarily for liquid flow measurement.
Note: Do not change the measurement mode or values unless recommended by Panametrics Sensing.
From the Signal Parameter tab, press the [

] arrow key to move to the Meas Mode tab. The window appears similar
to Figure 145 below.

in the Signal Setup Option
The first prompt asks for the measurement mode detection method. Use the [

] and [

] arrow keys to move to the
appropriate radio button and press [ENTER] .
You must now enter the setup data covered on page 50, if you have not already done so. Pressing the [

] key takes
you to “Skan/Measure Setup.” Press [ENTER] to open the Skan/Measure option and enter the parameters discussed
on page 55.
You have completed entering data for the Measurement Mode. To leave this window,
• Press the [

] key to return to the Measurement Mode tab, and the [

] arrow key to move to the Signal
Parameter tab or the [

] arrow key to move to the Pulse/Code tab.
• Press [F2] (Cancel) to return to Operate Mode without confirming the changes.
• Press [F3] (OK) to confirm the new data and return to Operate Mode.
