Combined calibration

When clicking the  button, you should see the dialog shown below. If you in step 2. choose to perform a combined calibration  there are only 4 steps, as shown below

Step 1. is explained in the next section.

In step 3. the user can either click the  button and follow the calibration procedure or type the Maximum input SPL level manually after clicking the  button.

If clicking the  button, the dialog shown below is displayed

In step 1, select if you want to use the sound card output or an calibrator as source.

In step 2, select the calibration frequency. If you use an external generator this must be set to sinusoidal signal with the frequency that is set here.

In step 3 connect the source you have selected the input. You might want to click the  button to test the level. You will be given a warning when performing the calibration if the level is not set correctly.

In step 4, enter the calibrator SPL-level.

In step 5, click the  button. This will perform the calibration and check that the level is sufficient and the distortion is not too high. If this is OK; the calibration is finished, the dialog box is closed and the calibration time and date is written in the Input level calibration dialog
