Command Response Description
O7E
Model
description
Enables flow mode.
O7D Model
description
Enables speed mode (default).
O8E Model
description
Sets m
3
/min as flow unit of measurement .
O8D Model
description
Sets L/s as flow unit of measurement.
CK n.n…
&
Sets the Pitot or Darcy tube coefficient to the value n.n…
The value must be between 0.6 and 1.2 (default = 1).
RK
n.nnnnn|
Reads the value of the Pitot or Darcy tube coefficient set in the
transmitter.
D nnnn
nnnn mmq |
Sets and reads the duct section in mm 2 .
CD n.n
&
Sets the “Debimo” blades coefficient to the value n.n (default=0.8).
CB
nnnn.nn…
&
Sets the barometric pressure to the value nnnn.nn… mbar. The val-
ue must be between 500 and 1500 mbar (default = 1013.25 mbar).
RB
nnnn.nnn|
Reads the value of the barometric pressure in mbar set in the
transmitter.
CT n…
&
Sets the airflow temperature in tenths of °C (default = 160 ⇒ 16.0 °C).
The value must be between -999 (
⇒
-99.9 °C) and 2000 (
⇒
200.0 °C).
RT
n…|
Reads the value of the temperature, in tenths of °C, set in the
transmitter.
CP nnnn…
&
Sets the differential static pressure (see note 2) in mbar (default = 0).
RP
nnnn…|
Reads the value of the differential static pressure set in the
transmitter.
CS nnnn
&
In speed mode, sets the full scale speed, in hundredths of m/s, for
the analog output (default = see table). The max settable value is
10000 (
⇒
100.00 m/s). In flow mode, sets the full scale flow in L/s
or m 3 /min.
RS
nn.nn|
In speed mode, reads the speed full scale value, in m/s, for the
analog output. In flow mode, reads the flow full scale value, in L/s
or m 3 /min, for the analog output.
SV
nn.nn|
In speed mode, prints the max measurable speed as a function of
the transmitter full scale pressure and values set for the parame-
ters. The value is in the speed unit of measurement set in the
transmitter. In flow mode, prints the max measurable flow in L/s or
m 3 /min.
Note: To exit the configuration mode after sending the CAL START command, send
the CAL END command (the transmitter automatically exits the configuration mode af-
ter 5 minutes from the last command sent).
