Make sure that the Barometer is not in a situation where the pressure is greater or lower than the range of the device. (Maximum elevation is approximately 7000 feet.)<\/li>\n<li><strong>Secondary Test:<\/strong> If the Barometer readings do not compare with the barometric pressure reported by a local airport or television station, then it is because the broadcast pressure is a corrected value. If you want your Barometer to read sea-level pressure (to compare with a weather report), perform a single-point calibration using the reported pressure for your elevation.<\/li>\n<\/ul>\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<h3 class=\"wp-block-heading\">Additional Troubleshooting<\/h3>\n<ul class=\"wp-block-list\">\n<li><a href=\"\/til\/1138\/\">Why doesn't my Barometer show the same pressure as the weather report?<\/a><\/li>\n<\/ul>\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<h3 class=\"wp-block-heading\">Specifications<\/h3>\n<ul class=\"wp-block-list\">\n<li>Sensing Element: SenSym SDX15A4<\/li>\n<li>Pressure Range (as shipped): 77.98 kPa to 105.29 kPa <br \/>(~0.77 to 1.04 atm or ~585 to 788 mm Hg)<\/li>\n<li>Maximum pressure that the sensor can tolerate without permanent damage: 310 kPa<\/li>\n<li>Typical Resolution: 0.00830 kPa<\/li>\n<li>Combined Linearity and Hysteresis: \u00b10.5% full scale<\/li>\n<li>Response Time: 100 microseconds<\/li>\n<li>Temperature Range: -25 to 85\u00b0C<\/li>\n<\/ul>\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<h3 class=\"wp-block-heading\">Calibration<\/h3>\n<p>Calibrate?
