Example 2:

Start a supervisor measurement with CRC and request the data:

0MC5!00014<cr><lf> (measurement ready in one second and 4
parameters available)

0<cr><lf> (measurement completed)

0D0!0+34.3+10.5+10.7+3.366DpD<cr><lf>

Continuous Measurement (aR)

The device can be configured so that all the parameters can be requested
instantly with the command aR instead of the two phase request
procedure of commands aM, aMC, aC, aCC + aD. In this case the
obtained parameter values are those from the latest internal updating
(for setting of update intervals, see

Chapter 8, Sensor and Data Message

Settings, on page 95

NOTE

For using Continuous measurement commands for wind and
