ADM-870C 07/14/098
IN ± n.nnnn
Indicates that the result represents a differential pressure measurement (in wc).
Metric Units
Bar n.nnn
Indicates that the result represents an absolute pressure measurement (bar). (One bar = 100 kPa).
/ C ± nnn.n
Indicates that the displayed result represents a temperature measurement (
/ C).
LSc ± nnnn
Indicates that the result represents an air flow measurement (L/s). "C" indicates that the result has been
compensated for backpressure effects.
LSu ± nnnn
Indicates that the result represents an air flow measurement (L/s). "U" indicates that the result has not been
compensated for backpressure effects.
Pa ± nnn.nn
Indicates that the result represents a differential pressure measurement (Pa).
MS ± nnn.nn
Indicates that the displayed result represents a velocity measurement (m/s).
4.3 FUNCTION READOUTS
The following prompts and messages are listed in alphabetical order.
$ $ $ $ $ $ $ $
Blocks of pixels will be displayed to test the operation of the display each time the meter is turned on.
nnc nnnn
Displays the number of backpressure compensated readings in memory and the average of just the backpressure
compensated readings taken during a FlowHood reading sequence. If there are no backpressure compensated
readings in memory, the display will read nnc NONE.
nnc NONE
Displayed if there are no backpressure compensated readings in memory during a FlowHood reading sequence.
nn
R n.nnnn
Displays the current reading and its place in the reading sequence during an automatic or manual STORE sequence.
Number of decimal places will vary.
nn
R NP 0
Indicates that the current reading in an automatic or manual STORE sequence is a negative pitot tube reading.
nnRc nnnn
This message indicates that backpressure compensated air flow readings are being stored. The display shows the
current reading and its order in the reading sequence during an automatic or manual STORE process.
nn
Ru nnnn
This message indicates that nonbackpressure compensated air flow readings are being stored. The display shows
the current reading and its order in the reading sequence during an automatic or manual STORE process.
nn
S n.nnnn
Displays a reading in memory and its place in the stored reading sequence. Accessed using forward or reverse
RECALL keys. Number of decimal places will vary.
nn
S ERASED
This message indicates that the current reading displayed in RECALL (nn
s
) has been erased.
nns NP 0
This message is displayed when a stored negative pitot tube reading is accessed using a RECALL key.
