Dial-A-Pipe Step 2: Navigate to the “Insertion Depth” screen. Use Table 3: Calibration Sub-
Menu for guidance.
Pipe insertion depth is automatically set to the pipe centerline unless adjusted here. For some
large pipes where centerline placement is not possible. An insertion depth of 5 inches is
suggested.
The display will show probe insertion depth in the same units as the selected Dial-A-Pipe ID units
in the step above. In the example below the insertion depth of the probe is 2.013000.
Press enter

to cause the first digit (the 2 in 2.013000 in our example) to begin flashing. Use
the up

and down

arrows to select the value 0 to 9. Once done, use the right key to move on
to the selected significant digit. Once the Insertion Depth value is selected, press enter

to
accept this value.
It is vital to use the correct Insertion Depth of the probe where the instrument is located.
Dial-A-Pipe Step 3: Pipe roughness does matter. The friction losses of the gas moving through
the pipe are a major factor in the instruments calculation of the flow profile. Navigate to the
“Pipe Type” screen. Use Table 3: Calibration Sub-Menu for guidance.
Use this menu screen to complete entering Dial-A-Pipe data. The display will show pipe
roughness and the “type” of pipe. See example below:
Press enter

and the type of pipe will begin flashing. Go to the next level down with the
