Change a Measurement type in the Measurement Details section

Okay, no problems! A measurement type can easily be changed from the Unit Type drop-down field in the measurement type. Simply click on the drop-down field and select the desired measurement type from the list. Once you click on the new option, the PTW will display a pop-up to confirm that your new selection. Click OK to continue the change:

In some cases, when the measurement type is a concentration one, some of the options in the dropdown don't display. There is a very simple fix to this; select a non-concentration measurement type and wait for it change. Once done, click in the Unit Type field again and all the different measurement type options should be displayed. Select the desired one to change to that measurement type.
