The Eco-celli barometer is calibrated to sea level (0 feet). When you install the barometer in an area that has a different height (more than 100 feet) above or below sea level, you will need to calibrate your barometer. A calibration kit comprised of a syringe, needle stub, and capillary tube was included with your barometer. There are two methods of calibration. Method one: the first thing you will need is the current local air pressure. Contact a local airport, television station, National Weather Service office, or visit a weather web site such as weather.com. Once you have the correct local air pressure, remove fluid from the red tube using the calibration set until the fluid level matches the correct air pressure. Have paper towels available to catch any spills as the colored oil will stain anything it comes in contact.

The second calibration method is to calculate the air pressure difference from sea level. To find your height above sea level, contact your local city/town hall. Each 25 feet above sea level is equal to 0.03 inches on the scale. Remove the calculated amount of fluid until the correct fluid level is reached. Please save the removed fluid in the syringe so it may be added if the barometer is moved to a different location.

TRANSPORTATION. If the barometer is to be transported, you should close the end of the barometer tube with the rubber hose and rubber stopper.

MAINTENANCE. Use a dry lint free cloth. Use of abrasive cleaning products is prohibited. Woodwork and metal parts can be maintained with the help of a bee-wax containing spray and lint free cloth. DO NOT spray directly onto the instrument. Spray a bit of product onto a cloth and gently rub the woodwork and metal parts.
