What must be completed prior to sampling with Dust Trak II?

• A. Conduct a performance audit
• B. Perform Zero Calibration
• C. Check battery levels
• D. Calibrate the alcohol wick

Answer: (B)

Prior to sampling with the Dust Trak II, performing zero calibration is essential to ensure the accuracy and reliability of the readings obtained from the device. Zero calibration involves setting the instrument to recognize the background level of particulate matter in the air, effectively calibrating it to a baseline of zero if there are no particulates present. This process helps to eliminate any inherent noise or drift in the instrument's readings, ensuring that any subsequent measurements accurately reflect the true concentration of airborne dust or particulate matter. By conducting zero calibration, users can achieve precise and meaningful data collection, which is critical for effective occupational hygiene monitoring. This step is particularly important because any errors in the baseline can lead to misinterpretation of air quality and potential health risks for workers exposed to harmful dust levels.
