11 3.2 The Calibration Utility 3.2.1 General The calibration utility (LCIC-WIM-CALIBRATION) enables to calibrate the LCIC-WIM board adjusting it to your own system. The utility is straightforward and is in the form of a Windows wizard. It includes three main stages carried out in five steps. The three stages are: 1. Show Data (step 1) (Described be ...
-
Omega Speaker Systems LCIC-WIM-BEN - page 13
12 The five calibration steps are: Step 1 – Show Data This step introduces both the parameters and the current readings , as received from the board. The step is passive in the sense that it only shows data passed by the board, but it does not make any change in the board. Some additional parameters may be displayed in the bottom of the “Curren ...

Omega Speaker Systems LCIC-WIM-BEN - page 14
13 Step 2 – Pseudo Calibration / Parameters This step starts the calibration procedure. It enables to change calibration parameters. Whether you changed the parameters or not, you may proceed to the next step by pressing the ‘Next’ button. Library issues: 1. Alternatively, you may click ‘Library’ in order to access the library, as describ ...
-
Omega Speaker Systems LCIC-WIM-BEN - page 15
14 Step 3 – Pseudo Calibration / Zero This step enables to redefine the ‘zero’ level. Click ‘Skip’ if you are satisfied with the previous definition of the ‘zero’ level. Otherwise, when the scale is empty and stable (see note), click ‘Zero’ to sample another ‘zero’ level. Once you clicked ‘Zero’, you may either confirm the ...
-
Omega Speaker Systems LCIC-WIM-BEN - page 16
15 Step 4 – Pseudo Calibration / Weight This step enables to redefine the ‘weight’ level. Click ‘Skip’ if the previous ‘weight’ level was OK. Even if there was a fixed shift in the weight (which you probably corrected in step 3), you don’t have to redefine the ‘weight’ level – just click ‘Skip’. Otherwise, specify the valu ...
-
Omega Speaker Systems LCIC-WIM-BEN - page 17
16 Step 5 – Save or Quit This is the final step – here you decide whether to confirm the pseudo calibration, or leave it out. Before you decide, you may watch the current readings examining whether they are satisfactory. • In case you do want to confirm the new (pseudo) calibration (overwriting the previous calibration), press the ‘Save to ...
