4 Making Measurements
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.)
Using implied read
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.
