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<CR><LF>

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

<CR><LF> =

Example of the command and response:
