Plus will start to beep slowly,
approximately once every 2 seconds, when the reading is within 50%
percent of the target reading, and it will beep faster, once every second or

within the designated percentage the beep will change to a chirp, several
beeps per second, informing the user that the setpoint window has been
reached. Press a second time, while in
BALANCE MODE,
to display the
difference between the real flow rate and the target flow rate on the large
digits. Negative values appear when the real flow is below the target flow
rate.
