Date: September 9, 2005 To: Aer E 161 Students From: Dana Haugli, Instructor DGH Subject: Example Technician Report Format The purpose of this report is to provide an example of a technician report. Technician reports are also called test reports, because they typically contain the results of tests performed as part of a project or experiment. Like any technical report, technician reports should be reviewed for clarity, grammar and spelling, and should be presented in a professional manner (typed, with type-set equations, clear margins and lack of crowding). All tables and figures should be identified in the text and labeled clearly. The test report consists of three sections, which follow. These sections cover experimental procedures, equipment and data. Procedures. This section does not restate procedures, but rather, documents where the procedures are located and what changes were made to the procedures. An example might be, “The procedures followed during these tests are documented in the file, ‘test.doc,’ on the desktop of the laboratory computer. No changes were made to the procedures.” If changes are necessary because something about the experiment would not work or a specific procedure cannot be followed, document the changes. For example, “Step 3 was changed because the probe described in the procedure would not fit, so the next smaller version of the probe was used.” Equipment. This section identifies the specific equipment used in an experiment. The documentation, usually in the form of a table such as the example in Table 1, includes descriptive information such as the serial number, to help recreate the tests with the same equipment if necessary. Pictures of the equipment or setup may also be included, such as in Figure 1 (next page). Tables and Figures should be placed as close to the text that refers to them as possible, in the order to which they are first referred. Table 1. Example equipment identification table^1.

No analysis or discussion is required, except where such discussion might clarify how the data was collected. Table 2. Data from an oscilloscope in the Aer E 161 Lab during an accelerometer test.
