Sigma LBA-712, LBA-710 Computation... Energy calibration select results items, Logging, Print

3.2.5.1Logging

This switch will launch you into the Data & Results Logging dialog box.

3.2.5.2Print

This switch will cause the selected print options to be printed on your configured printer. You will not get a chance to reconfigure your printer or print setup item when you click this tool, so be sure that you have set your options up in File, Print Setup... before you click here.

3.2.5.3Write Protect

This tool can be used to write protect any frame in the frame buffer. Before clicking on this tool, be sure that the frame number that you want to write protect is indicated in the frame counter.

The frame counter is located in the lower right corner of the main window. When a frame has been write protected, its location in the frame buffer can not be overwritten. When new data is flowing into the frame buffer, write protected locations will be skipped.

To un-write-protect a location, bring the frame number up again and note that the write protect button is still in the depressed position; click the tool a second time. This tool’s button will show in the un-depressed state to indicate that the frame is no longer write-protected. Therefore, the only way to determine which frames are write-protected is to cycle through the frames and simultaneously view the up/down state of the write-protect button.

Caution: If you change the frame buffer resolution, all write protected frames and their contents will be deleted.

3.2.6Computation... Energy calibration select results items

The Computations dialog box is where you select the types of numerical results that you want to have calculated and displayed. You can also calibrate the beam energy here.

Note: The term energy, shown in Italic, will be used to represent both Energy and Power.

3.2.6.1Energy of Beam

The Energy of Beam edit control item lets you calibrate the LBA to the energy of your laser. You must measure the energy of your beam using an external measuring device, then enter the energy value here. Next select the appropriate units in the Energy Units item. The value entered must be the total energy of the frame currently displayed. For accurate results, the beam must be completely contained inside the current Hardware Zoom/Pan window, and an Ultracal! operation should be performed prior to collecting the frame used for energy calibration.
