Display modes

Normal – Updates display with each new result

Max Hold – Updates displayed point only if new point > old

Min Hold – Updates displayed point only if new point < old

Max/Min Hold – Displays a vertical bar between Max Hold and Min Hold

Average – Displays average of N (specified by user) acquisitions

Average is calculated as follows:

Last N values are saved in memory; when a new result is available, the earliest result of the N stored values is discarded, the new result is added to the stored values, and a new average is calculated from the stored values. If the number of results is less than N, then all of the results are averaged together

Number of averages

1 ≤ N ≤ 200
