A professional who tests, calibrates, and adjusts aneroid barometers to obtain specified performance, using handtools and test equipment. Responsibilities include:

• Places barometer in vacuum chamber and connects barometer to master barometer (mercurial or electronic).
• Starts vacuum pump to decrease atmospheric pressure in vacuum chamber, and records variances of readings between aneroid and master barometer at different atmospheric pressures, manually or using computer.
• Calculates adjustments required and calibrates barometer, using handtools, or automatically calibrates barometer to specifications, using computer.
• Tests calibrated barometer to ensure calibration conforms to master barometer.
• Prepares and maintains manual or computerized test and calibration records.
• May test calibration of aneroid barometers, using radio frequency signals recorded on tape.
• May disassemble, inspect, and replace defective barometer parts.
