– Query command: The INBUF? query command returns the present input buffer
Example
The following program enables the input buffer prior to running all of the
autocalibration routines. This prevents the bus from being held during the autocal
which takes over 11 minutes to complete.

ISCALE?
Integer scale query. Returns the scale factor for readings output in the SINT or
DINT formats.
Syntax
ISCALE?
Remarks
– The scale factor is always 1 for the ASCII, SREAL, and DREAL output formats.
– Readings output in the SINT or DINT formats (see the

are first compressed by the multimeter so they may be expressed as integers.
Multiplying the readings by the value returned by ISCALE? will restore them to
their actual values. The scale factor is determined by the configuration of the
multimeter when ISCALE? is executed. This includes the measurement
function, range, and integration time. Therefore, the multimeter's
configuration must be the same when the scale factor is retrieved as it was
when the readings were taken. You can retrieve the scale factor after the
