2.Press any key to enter the main menu. Move the cursor to "Program" and press Enter (F4).

3.Move the cursor to "Configure" and press Enter (F4).

4.Move the cursor to "Barometric pressure" and press Enter (F4).

5.Use the é and ê keys to move through the list of items. To make a change, press Edit (F4). Use the arrow keys to change settings to the desired value and press Save (F4).

Bar meas: The controller has an on-board sensor that automatically measures barometric pressure. To bypass the pressure sensor, select "Manual'. Be sure to enter the desired pressure in the third line. During air calibration, the controller will use the barometric pressure entered in this step no matter what the true pressure is.

Bar units: Select the units in which barometric pressure will be dis- played.
