*STB?
Read Status Byte Query
. Queries the condition register for the
group and returns a
decimal value equal to the binary-weighted sum of all bits set in the register.
A condition register continuously monitors the state of the instrument. Condition register bits are updated
in real time; they are neither latched nor buffered.

After setting the trigger source, you must send
to place the DMM in the "wait-for-trigger"
state. The *TRG command is not accepted unless the DMM is in the "wait-for-trigger" state.
