9-28 Servicing the PT878GC
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 GE Pana metrics.
From the Signal Parameter tab, press the [X] arrow key to move
to the Meas Mode tab. The window appears similar to Figure
9-17 below.
