Vaisala WMT700 - Manual (Page 177)

Chapter 5 _________________________________________________________________ Operation
aV! — Start Verification
This command starts verification. However, WMT700 does not
return verification data directly after this command. It sends a
response that specifies when the verification results can be
retrieved using the aD0! command and the number of parameters.
The WMT700 verification data includes a watchdog count, sensor
measurement unit settings, and the current SDI mode setting.
The command is the following:
aV!
where
a = Single-digit WMT700 address that corresponds to the
first character of the address value
V = Starts verification command
! = Terminates the command
The response is the following:
atttn
where
a = Single-digit WMT700 address that corresponds to the
first character of the address value
ttt = Period of time, in seconds, after which WMT700 has
the verification data ready
n = Number of verification data fields that will be returned
= Terminates the response
Example of the command and response:
1V!
10014
Interpretation of the example message:
- Time when the measurement is ready: 1 second
- Number of returned measurement values: 4
To fetch the measurement results, use the aD0! command.
