Navigating and Customizing Your FP-25

Averaged Data in Standard Mode

The averaging screen of Standard Mode displays averaged data for all flow 

parameters simultaneously. Flow data is measured at a rate of 1000 readings 

for every second of measurement time. Press the button above or below any 

of the four flow parameters to highlight its value in the center of the screen, 

even after an averaged measurement has finished. Engineering units cannot 

be changed from the averaging screen. 
•  When an average is running, the screen displays Running Avg at the top, and 

all parameter values update in real time until the average has completed. 

When the countdown timer stops, the screen displays Final Avg at the top. 

Note: If you have chosen the time remaining to be highlighted in the 

center of the display, this parameter will disappear once the averaged 

measurement is finished, just as its smaller counterpart in the top right 

of the display disappears and becomes 

START AVG

. The time remaining 

parameter will reappear in the center when you start a new average.
