CALIBRATION
Press

Calibration
and
to enter. Use
or

menu item and
to enter. When settings are completed press
to store and
return to the Calibration menu.
20mA at
Press
then
or
to change the numbers and decimal
point. Use this menu to set the corresponding flow rate
that will be represented by 20mA analog output. If
maximum flow is unknown, enter an estimated flow rate
and observe actual flow to determine the correct
maximum value. Any velocity or flow rate up to +40
ft/sec (12.2 m/sec) may be selected.
4mA at
Press
or
to set the flow rate corresponding to 4mA
analog output. This setting may be left at zero flow (or
velocity or can be raised to any value less than the 20mA
setting, or lowered to any velocity or corresponding flow
rate down to -40 ft/sec (-12.2 m/sec).
Min Flow
Flow rates below this setting will be displayed as zero
flow.
Damping
Increase damping to stabilize readings under turbulent
flow conditions. Decrease for fast response to small
changes in flow. Damping is shown in percentage
(maximum is 99%). Factory default is 20%.
Press
