Velocity* **
(SFPM)
– Standard feet per minute
(M/S)
– Meters per second
Flow* **
(SCFM)
– Standard cubic feet per minute
(M3/S)
– Cubic meters per second
*The displayed reading is based on standard conditions – dry air at 70° F and a
barometric pressure of 29.92 inches of mercury.
**The control will automatically switch to x10 or x100 for velocity or flow when
the reading exceeds four digits. This will be indicated on the LED by alternating
the flow or velocity reading with the “
α
10” or “
α
100” symbol. The maximum
displayed velocity or flow will be 9999 x100 regardless of units.

Resolution (Res)
– The pressure reading on the LED display can be shown
with 3 or 4 digits. In some cases, the fourth digit is outside of the accuracy
of the product and insignificant. If the fourth digit is used and is
insignificant, there may be fluctuations in that digit.
3 Digit (3 dig)
– 3 digit display
4 Digit (4 dig)
– 4 digit display
Display (Dis)
– In addition to the selectable units for pressure, velocity, and
flow, the display can also be configured to read as a percent output.
Standard (std)
– Displays selected engineering unit
Percent (pct)
– Displays 0-100% instead of the selected engineering
unit
