The deadband threshold (DISPLAY AS ZERO) is the value below which the ow
controller displays all ow readings as "0" (no ow). This function also applies
to gauge pressure readings when using the optional barometer. By default,
ow controllers ship with a deadband value of 0.25%, so on a 20-slpm
instrument, all readings below 0.05 slpm would display as 0 slpm.
Note: Deadband settings do not aect the values reported in the serial
data frame.
The AVERAGING button opens a submenu for adjusting
the ow and pressure averaging, which are changed
independently. Values roughly correspond to the time
constant (in milliseconds) of the averaged values. Higher
numbers generate a greater smoothing effect on
rapidly fluctuating readings (max 255 ms).
