Command Response Description
<value6> – Vibration index
Format: +00b [1]
+000 = No device vibration
+
001 = Slight device vibration
+002 = Significant device vibration
➝ impaired measured values
+003 = Very significant device vibration;
➝ unacceptable measured values
aR0!
a<value1><value2><value3> …
… <value4><value5><value6> …
… <CR><LF>
The OTT SVR 100 continuously measures the flow velocity
This command enables measured results to be obtained even
without the aM!/aD0! command combination; for details
see aD0! command.
a
MC!
a
tttn<CR><LF>
Start measurement and request CRC (Cyclic Redundancy
Check); for details see aM!command.
The response to the subsequent aD0! command is extended
with a CRC value: a<value1><value2><value3> …
… <value4><value5><value6><CRC><CR><LF>
aC! atttnn<CR><LF>
Start measurement and request CRC (Cyclic Redundancy
Check); for details see aM!command. The number of mea-
sured values in the response to this command has two digits:
nn = 06.
aCC! atttnn<CR><LF>
Start concurrent measurement (simultaneous measurement
with multiple sensors on one bus line) and request CRC
(Cyclic Redundancy Check); for details see aM!. The number
of measured values in the response to this command has two
digits: nn = 06.
The response to the subsequent aD0! command is extended
with a CRC value: a<value1><value2><value3> …
… <value4><value5><value6><CRC><CR><LF>
aV! atttn<CR><LF>
Perform system test
a – Sensor address
ttt – Time in seconds until the sensor provides the
result of the system test
OTT SVR 100 response = 000
n – Number of measured values
OTT SVR 100 response = 2
aD0! a<value1><value2><CR><LF>
Send data (after aV!)
a – Sensor address
<va1ue1> – Result of system test: Firmware
+0 = Internal error occured
+1 = Firmware working properly
<value2> – Result of system test: Internal sensors …
+0 = are (partially) inactive
+1 = are all active
