8. Store a series of measurements
Thanks to the zero pressure compensation of the FlowFinder, it is possible to measure the air flow at a
part of the diffuser. Because the FlowFinder actively compensates its own resistance, the flow through
the other (free) part of the diffuser will not or hardly be influenced.
This way, as an example, the flow through a line diffuser can be measured by moving the FlowFinder
across the diffuser evenly after every measurement, and adding the measured values.
1. Make sure there is a micro SD card in the micro SD card
slot to be found at the right lower side of the display. If

2. Execute a measurement in “Validate” mode as described
in chapter 8

6. Touch the button of your choice and a numerical
keypad will show.
7. Here you can type in a 4-digit numerical identifier
which is then added to the record of this
measurement. This number can be a house number
or some number from a plan or some clever
combination. You are free to design your own data-id
system.
