It shows the current environmental conditions for all the beams making up the preset. There are two ways of adjusting the environmental conditions of beams in the currently selected preset:

1. Input the desired values for temperature (°C), humidity (%), and atmospheric pressure (hPa). HOLOPLOT Control accepts decimal points with a comma (,) or a period (.).
2. Depending on when you want to apply the values, you can:
   * Click **Apply** to use the newly input environmental conditions immediately.
   * Click **Save** to use the newly input environmental conditions on the subsequent preset switching.
