9.2 Taking a Static Pressure (SP) Measurement
Four readings are shown on screen and pressing the Up and Down Keys will scroll up and down to view the
readings. Scroll down to use the SP (Static Pressure) function.
Press the right soft key to begin sampling.
Zero the readings by pressing the Middle Soft Key (Zero).
Press the right soft key to stop sampling.
To measure the Static Pressure connect the Flow Sample pipe to the SP connection as shown in the diagram above.
The flow sample pipe is the section of pipe without the filter. This can be separated from the Gas Sample pipe at
the quick release coupling.
Connect the male fitting to the "SP" connection.
IMPORTANT: It is important to complete the zeroing in an environment where there is no flow or pressure
and ensure that the end of the flow tube is not exposed to any external flows or pressures.
