B.2.3 Initiate Verify Command
The Verify Command may cause a verify of tests or procedures to be performed. The result of
this command is similar to the "aM!" command except that the values generated can be fixed test
data, test results, etc. The data generated in response to this command is placed in the sensor's
buffer for subsequent collection using "D" commands. The data will be retained in the sensor
until another command is executed.
Command Response Description

a Is the sensor address ("0" to "9", "A" to "Z", or "*").
V Is an upper-case ASCII character.
ttt Is a three digit integer (000-999) specifying the maximum time, in seconds, the
sensor will take to complete the command and have data available in its buffer.
n Is a single digit integer (0-9) specifying the number of values that will be placed in
the data buffer. If "n" is zero (0), no data will be available using subsequent "D"

the sensor. Any measurement data in the sensor's buffer is not disturbed.
