The mnemonic DEF means DEFault. This is not equivalent to the DEFault parameter used in the
command sub-systems. The parameters must be entered in the specified order. If parameters are
omitted, they default from the right. The parameter DEFault is used as a place holder. Specifying
DEF leaves the parameter value unchanged.

When the measurement result is linear this parameter represents the number of significant

respectively.
