Delay Operation

Delay can be set by either time or distance. Distance can be expressed in either feet or meters. The default setting is by Time, at 100.0ms. When Feet or Meters is chosen, the Temperature field becomes available and can be set by either degrees Fahrenheit or Celsius.

Temperature value calculates the change in the speed of sound as modified by air temperature, and adjusts the time value with the appropriate delay time compensation. Procedurally, first enter a temperature value, and then set the distance in feet.

To set Delay by Time:

1. The Delay dialog defaults to Time units. Or, click Time in the Units section of the Delay dialog to set Units to Time.

2. Set Delay slider by one of the following methods.

• Click + hold slider handle and drag to desired value.

• Highlight the text in the value field and type desired value.

• Click slider handle to focus. Use up or down arrow keys to adjust slider in 1.0ms increments.

3. Click OK.

To set Delay by Distance:

1. Click Feet or Meters in the Units section of the Delay dialog to units of distance.

2. Set Temperature (optional) in the Conditions section of the dialog, either in Celsius or Fahrenheit. You may also leave this set to 70° F, which is a reasonable average for indoor use.

3. Set the Delay slider by one of the following methods.

• Click + hold slider handle and drag to desired value.

• Highlight the text in the value field and type desired value.

• Click slider handle to focus. Use up or down arrow keys to adjust slider in 1.0ms increments.
