Entering Transducer Parameters (cont.)

Note: The choices made earlier in the Transducer and Pipe
options determine the prompts available later. If the
PT878GC does not scroll to a particular parameter, it is
not necessary for tha t transducer or pipe type.
2. The next prompt asks you to enter the transducer number , or to
specify that you are using a special application transducer.
a. From the Type prompt, press the [T] key to reach the
Transducer prompt, and press [ENTER].
b. A drop-down list of transducer numbers opens, if you have
selected clamp-on in the previous prompt. Press the [T] or
[S] keys to scroll to the appropriate number, or scroll to
“Special” for a special application transducer. To speed
scrolling, you can press the [X] key to scroll down by a
page, or the [W] key to scroll up by a page.
c. Press [ENTER] to confirm your selection.
The program now varies, depending on whether you have
selected preprogrammed or special transducers.
If you have selected a transducer from the list of
preprogrammed shear clamp-on transducers (#301 to 315), the
PT878GC comes programmed with the needed parameters.
You only need to enter the wedge temperature.
a. From the Wedge Angle prompt, press the [T] key to reach
the Wedge Temperature prompt, and press [ENTER].
b. Use the numeric keys to enter the wedge temperature (in
degrees) and press [ENTER].
Note: For highest accuracy, measure the wedge temperature on
the transducer wedge.
Pressing the [T] key thus returns the meter to the Transducer tab
at the top. Go to page 4-7 to continue programming.
However , if you have selected a special application transducer ,
turn to the next page.
