The stored readings can now be accessed by individual reading number (1
through 80) or by record/reading number (e.g. the 3rd reading in record 2
"
is also reading number 13). For example, the following program returns and
displays reading number 50 (the 31st reading taken by the above program).
!RECALL READING NUMBER 50
!ENTER READING
!PRINT READING
The following program uses the first parameter and the count parameter to
return and display the readings numbered 12 through 17.
!COMPUTER ARRAY NUMBERING STARTS AT 1
!DIMENSION ARRAY FOR 6 READINGS
!RECALL 6 READINGS, STARTING WITH #12
!ENTER READINGS
!PRINT READINGS
You can also use record numbers when recalling readings. The multimeter
assigns the lowest record number (1) to the most recent record and the highest
number to the oldest record. The following program returns the 3rd and 4th
reading in record number 6 {in this case, readings numbered 53 and 54,
respectively).
!COMPUTER ARRAY NUMBERING STARTS AT 1
!DIMENSION ARRAY FOR READINGS
!RECALL 3rd & 4th READINGS FROM RECORD #6
!ENTER READINGS

When executing RMEM from the front panel, after recalling a reading by
reading number, you can use the up or down arrow keys to scroll through the
other readings in memory. (The RMEM command is the only way to retrieve
stored readings from the front panel.)
When the controller requests data from the multimeter and its output buffer
is empty with reading memory enabled, a reading is removed from memory,
placed in the output buffer, and transferred to the controller. This is the
"implied read" method of recalling readings. Unlike the RMEM command,
the implied read removes readings from memory. In the LIFO mode, the most
recent reading is returned. In the FIFO mode, the oldest reading is returned.
The following program makes 200 readings, places them in reading memory,
and uses the implied read to transfer the readings to the controller.
