1. If a MATH function (mX+B, percent or 1/X) is enabled, the result of the calculation will
be returned.
If there is no MATH function enabled, FETCh? and CALC:DATA? will return
the basic reading.
MATH functions are covered in Section 5.
2. None of these read commands trigger measurements. They simply return the lastest
reading. If FETCH?, CALC:DATA?, or DATA? is again sent before a new reading is
triggered, the ld reading will be returned.
3. DATA:FRESh? can only be used once to return the same reading. Sending it again before
a new reading is triggered will cause error -230 (data corrupt or stale).
