Impulse

On Impulse, why does air flow display OFF even though I have turned it on?

The air flow on Impulse is controlled by using the toggle switch on the touchscreen.

Toggle to the right to turn the air on and toggle to the left to turn the air off.

The toggle displays blue to show that the air on option has been selected.

Impulse Air Flow

The air flow will not start until the test has begun, which is why the display window still shows as off.

Once the test has started, the air flow comes on and the display window will change to ON.
