switch.
3.
Make sure the vent on the pump is open.
4.
Push to select P1 or P2 depending on how the
Product is connected.
5.
Zero the Product if necessary.
6.
Close the vent after the Product is zeroed.

Slowly apply pressure with the pump until the switch
opens.
In the SWITCHTEST mode the display update
rate is increased to help capture changing
pressure inputs. Even with this enhanced
