at all gain settings. These
measurements are stored and subtracted from subsequent measurements.
Acquisition is suspended during auto calibration and no other remote commands
will
be
processed until the auto calibration sequence is complete.
Returns: <number>
<number> represents the integer
0.
This return value is generated when
autocalibration
is
complete.

4).
Because this command does not clear the input
and output buffers the MAV bit will not
be
affected. The *CLS command also
cancels any outstanding *OPC and OPC? commands.
