●The FETCh? query does not erase measurements from the reading memory.
You can send the query multiple times to retrieve the same data.
●You can store up to 10,000 measurements in the reading memory of the
DM2571. If reading memory overflows,new measurements overwrite the
oldest measurements stored; the most recent measurements are always
preserved. No error is generated, but the Reading Mem Ovfl bit (bit 14) is set
in the Questionable Data Register's condition register.
