Remarks Executing the DMMRead function causes the DMM to perform a single conversion an
retrieve the result. The DMM, performs all scaling and conversion required, and returns
the result as a 64-bit double-precision floating-point number in the location pointed to by
lpdResult. It can read all the Primary functions (those that can be selected us
DMMSetFunction() and DMMSetRange() ). Returned result is a scaled value which is
normilized to the selected range. That is . That is, it returns 200 for 200mV input in the
240 mV range, and 100 for 100 kΩ input in the 330k Ω range. Alternatively use the
