4.0 DISPLAY MESSAGES AND PROMPTS
4.1 READ PROMPTS
The following ten prompts all include the term READ, which is a signal for the operator to press the READ key
to trigger the actual measurement.
English Units
CF: READ
This display indicates that the meter has been placed in the air flow function (cfm) and will appear
automatically upon power up (following FLO-HOOD) if the flaps plug of the FlowHood is connected to the
meter.
/ F: READ
This display indicates that the meter has been placed in the temperature function (
/ F).
FP: READ
This display indicates that the meter has been placed in a velocity function (fpm).
Hg: READ
This display indicates that the meter has been placed in the absolute pressure function (in Hg) with reference
to a vacuum.
IN: READ
This display indicates that the meter has been placed in the differential pressure function (in wc).
Metric Units
Bar: READ
This display indicates that the absolute pressure readings will be displayed in bars (1 bar = 100 kPa) with
reference to a vacuum.
/ C: READ
Display indicates that the temperature readings will be displayed in degrees Celsius (
/ C).
LS: READ
This display indicates that the meter has been placed in the air flow function and will read in liters per second
(L/s).
MS: READ
This display indicates that the velocity readings will be displayed in meters per second (m/s).
Pa: READ
This display indicates that differential pressure readings will be displayed in Pascals (Pa).
4.2 MEASUREMENT READOUTS
In the following 12 examples, n indicates a number in the displayed result. If no sign is displayed, the result is
a positive number. A negative sign indicates a negative number. English and metric units are shown for each
example.
English Units
CF:c ± nnnn
Indicates that the result represents an air flow measurement (cfm). "C" indicates that the result has been
compensated for backpressure effects.
CF:u ± nnnn
Indicates that the result represents an air flow measurement (cfm). "U" indicates that the result has not been
compensated for backpressure effects.
