Send data (after aHA! )
a – sensor address
<value10> – dew point in the probe housing 2)
<value11> – temperature in the probe housing 2)
<value12> – current sensor orientation
measured value format: pbbb [°] 2)
<value13> – sensor orientation during installation
measured value format: pbbb [°] 2)
<value14> – corrected pressure value of pressure sensor
measured value format: pbbbb.ee [mbar] 2)
<value15> – corrected pressure value of pressure sensor
including potential offset
measured value format:
pbbbb.ee [mbar]
<value16> – uncorrected pressure value of pressure sensor
measured value format: pbbbb.ee [mbar]
<value17> – discharge 2)
<value18> – device status; see aD2! after aV!
<CRC> – CRC value
Note
Measured value discharge =
-9999
➝
calculation error
occured or rating table missing; =
-9998
➝
entries in the
rating table are not sufficient for calculation
aHB! atttnnn<CR><LF>
Start "High volume" measurement in binary format and
request CRC (Cyclic Redundancy Check)
a – sensor address
ttt – time in seconds until the sensor has deter-
mined the measurement result
response OTT PLS 500: 0/1 … 60 seconds
1)
nnn – number of measured values
response OTT PLS 500: 17
aDB0!
Binary data header
SDI-12 sensor address "0"; packet size
64 bytes; 9 IEEE 32-bit floating point
numbers with single precision
Binary data Send data (after
aHB!
)
IEEE 32-bit floating point numbers with single precision
<value1>
…
<value17>
The measured values correspond
to the description of
aD0!
and
aD1!
after
aHA!
aDB1!
Binary data header
SDI-12 sensor address "0"; packet size
2 bytes; 4 unsigned 16-bit integer values
Binary data Send data (after aHB! )
unsigned 16-bit integer values
<value1> device status; see aD2! after aV!
1) depending on the set averaging time; advanced command aXXM<value>!
In the measurement type "continuous measurement" the time is always 0 seconds (with the exception of the first interval after the start)!
