significantly. Ten averages may take longer, but may be necessary when testing difficult, non-linear structures. To set up five averages, follow these steps:

•Press the [Avg] hardkey.

•Toggle the [AVERAGE ON OFF] softkey (F1) until ON is highlighted.

•Press the [NUMBER AVERAGES] softkey (F2).

•Enter 5 and press the [ENTER] softkey (F1).

To avoid averaging overloaded data, turn on overload reject as follows:

•Press the [Avg] hardkey.

•Toggle the [OVLD REJ ON OFF] softkey (F1) until ON is highlighted.

To start taking measurements,

•Press the yellow [Start] hardkey.

Hammer the structure at one measurement point. After the data is acquired and displayed, hammer the structure again, and repeat 5 times until the average is complete.
