	~~{{ugAddressingInformation}}~~		===About===
			The Barometer Phidget measures absolute pressures within the range of 50kPa and 110kPa at a resolution of 250 mPa. If you read air pressures outside this range, an error event will trigger.

	~~==Technical Details==~~		You can use your Control Panel to explore your Phidget's channels.
	~~===Barometric Temperature Correction===~~
	The PRE1000 reports the absolute pressure of its surroundings. In other words, the pressure compared to a perfect vacuum. If you plan on using this sensor as a barometer, you need to convert to barometric pressure. You can use ~~conversion calculators such as this [http://www.csgnetwork.com/barcorrecthcalc.html above sea level barometer reading correction calculator]~~ to ~~make the adjustment based on~~ your ~~location~~'s ~~elevation~~.

	=== ~~Use~~ as an Altimeter ~~===~~		'''1.''' Open your Control Panel, and you will find the following channel:

	Since the PRE1000 makes absolute pressure measurements, you could use it with a temperature sensor to measure changes in altitude, as long as you know your pressure and height to begin with. The following is the barometric formula:		Since the PRE1000 makes absolute pressure measurements, you could use it with a temperature sensor to measure changes in altitude, as long as you know your pressure and height to begin with. The following is the barometric formula:

	~~===~~Accuracy~~===~~		{{UGC-Entry\|Accuracy\|\|
	A long-run test was performed to compare the accuracy of the PRE1000 with that of the ~~[http://www.phidgets.com/products.php?product_id=1141_0~~ 1141 - ~~Asolute~~ Gas Pressure Sensor]. For 87 hours, both sensors measured the absolute air pressure indoors in the same room, with the same change sensitivity.		A long-run test was performed to compare the accuracy of the PRE1000 with that of the {{Prod\|1141}} - Absolute Gas Pressure Sensor. For 87 hours, both sensors measured the absolute air pressure indoors in the same room, with the same change sensitivity.

			As you can see, the PRE1000 is significantly less noisy. The average difference between any two successive samples for the 1141 is 237.17Pa, while for the PRE1000, it is 3.19Pa. Both sensors consistently differ by an average of 1.23kPa, but this error could be easily calibrated out due to the consistency of the offset.
