P Flashcards
What is the first step in zeroing a pressure gauge?
Fan off
Ensure that the fan is turned off to avoid any interference during the zeroing process.
In what position should the pressure gauge be during the zeroing process?
Vertical
The gauge should be placed in a vertical position to ensure accurate readings.
What should be done with the lines connected to the pressure gauge before zeroing?
Disconnect lines
Disconnecting the lines prevents any pressure from affecting the gauge during the zeroing process.
What is adjusted to zero a pressure gauge?
Turn zeroing screw
The zeroing screw is turned to calibrate the gauge to read zero when there is no pressure.
What are the typical pressure readings displayed on a gauge?
10, 20, 30
These are examples of pressure readings that a gauge may display, indicating different levels of pressure.
