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 that 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 [
Transducer prompt, and press
b. A drop-down list of transducer numbers opens, if you have
selected clamp-on in the previous prompt. Press the [

You only need to enter the wedge temperature.
a. From the Wedge Angle prompt, press the [
the Wedge Temperature prompt, and press
b. Use the numeric keys to enter the wedge temperature (in
degrees) and press
Note: For highest accuracy, program the wedge temperature to
the average of the gas and ambient temperatures. For
example, if the gas temperature is 350°, the wedge
temperature is (350+70)/2 = 210°F.
Pressing the [
