3.1.2 Change Line Size (i.e., pipe diameter)

The CMS instruments are configured at the factory for the line size specified. This is shown in

SECTION 8 - CUSTOM INFORMATION. If the probe is moved to a pipe with a different diameter
then it is important to change the line size so that the instrument will adjust the measured velocity and
report the correct volumetric flow rate. This is accomplished using the “Change Line Size” option.

The change line size menu can be accessed through the 3 button menu. Use Left and Right to

scroll through the options until Change Line Size is highlighted as shown in Figure 14. Then either wait
for the timer to expire or press Enter.
