pressure reading on Channel A and the peak percent speed on the bottom right-hand of the display.

Set the correct Device on your gauge because it will calculate different results depending on which Device
is selected.
8.12 Check if large fixed errors are caused by pinched tubes
A pinched pressure tube can create a very high reading on the gauge, which is erroneous. In other cases, a
pinched tube will prevent the pressure measurement from reaching the gauge at all. In cases where tubes
get stepped on, they are seldom sealed off completely, but will still cause the gauge readings to jump
around.
