Average
When the average math function is enabled, the instrument performs measurements and displays the
average reading in the secondary display. It can also display the minimum and maximum readings,
as well as the reading count.
The data acquired by the average math function is stored in volatile memory. It is lost when power to
the instrument is cycled or when the remote interface is reset.
The average math function can be used from the front panel or by using remote operation.
Front-panel operation
Perform the following steps to use the average math function:
1. Press the SHIFT and NULL (MATH) keys.
2. Use the ◄ and ► keys to display AVERAGE and press ENTER.
3. With RUN displayed, press ENTER. The MATH indicator turns on.
The primary (top) display shows the measured readings, and the secondary (bottom) display
shows the average (AVG) reading of the measurements that have already been performed.
4. Use the ◄ and ► keys to change the secondary display to show the maximum (MAX) minimum
(MIN) readings, and the reading count (COUNT).
You can disable the math operation by pressing a different function key. You can also disable it from
