CS100 Barometric Pressure Sensor
The value dP is in millibars and the site elevation, E, is in meters. Add dP
value to the offset in the measurement instruction.
Use Equation (2) to convert feet to meters.

The corrections involved can be significant: e.g. at 1000mb and 20°C,
barometric pressure will decrease by 1.1mb for every 10 meter increase in
altitude.
8. Maintenance and Calibration
Since the sensor is semi-sealed, minimum maintenance is required:
1. Visually inspect the cable connection to ensure it is clean and dry.
2. Visually inspect the casing for damage.
3. Ensure that the pneumatic connection and pipe are secure and undamaged.
The external case can be cleaned with a damp, lint-free cloth and a mild
detergent solution.
Contact Campbell Scientific, Inc. (435-227-9000) for an RMA number before
returning the sensor for recalibration. You may also return the unit directly to
Setra for recalibration.
Should you lose the five terminal connector (p/n 16004), the replacement part
can be purchased from Campbell Scientific, Inc. Contact Campbell Scientific,
Inc. to purchase the part.
The CS100 is sensitive to static when the backplate is
removed. To avoid damage, take adequate anti-static
measures when handling. CAUTION
