System pressure drop shall be a maximum of 3 kPa (1 inches Hg) at the calculated demand flow. The typical absolute pressure range for measuring vacuum pressures is 0 to 1 bar absolute. Since negative gauge and absolute reference vacuum ranges are measuring the same pressure it is often assumed that they are the same measurement carried out in different directions. WARNING: Ambient temp is the temperature at the vehicle under the hood, NOT THE WEATHER SERVICE. /ItalicAngle -12 I’d like a device to record this same information and allow me to populate a spreadsheet with the recorded data. /MaxWidth 2628 It is the pressure of a fluid, which is always less than atmospheric pressure.
