How often does TEC recommend calibration checks for their manometers?

• A. Bi-weekly checks
• B. Monthly checks
• C. Weekly checks
• D. Annual checks or as needed

Answer: (D)

The recommendation for calibration checks of manometers by TEC is to have these checks performed annually or as needed. This approach balances the need for accuracy and reliability in measurements taken during whole-building airtightness testing with practical considerations, such as frequency and cost. Regular calibration ensures that manometers provide accurate readings, which are critical for assessing the airtightness of buildings. Given that building airtightness testing is often performed less frequently than weekly or monthly, annual checks allow for sufficient time between calibrations while still ensuring the equipment is reliable when in use. Additionally, the phrase "or as needed" provides flexibility, allowing for more frequent checks if the manometer experiences rough handling or environmental conditions that could affect its performance. This method ensures compliance with industry standards while not imposing unnecessary burdens on testing schedules or resources.
