Tell us about a time when you had to troubleshoot a calibration issue. How did you approach it and what was the outcome?

In my previous role as a Junior Calibration Technician, I encountered a calibration issue with a temperature probe. I approached the problem by first checking the calibration history and comparing it to the expected values. I then performed a visual inspection of the probe for any signs of damage or deterioration. Next, I used a secondary reference thermometer to verify the accuracy of the probe's readings. After identifying a difference in the measurements, I adjusted the calibration settings of the probe using the appropriate software. Finally, I conducted multiple verification tests to ensure the issue was resolved. The outcome was a successfully calibrated temperature probe that met the required standards.

During my time as a Junior Calibration Technician, I faced a calibration issue with a pressure gauge. To approach the problem, I first reviewed the calibration procedure and identified the expected pressure values. Then, I conducted a visual inspection to check for any physical damage or debris that could affect the accuracy of the gauge. Next, I utilized a standard reference pressure calibrator to compare the readings of the gauge. After identifying a deviation, I adjusted the calibration settings of the gauge using the calibration software, ensuring the correct pressure readings. To validate the calibration, I performed multiple verification tests and recorded the results accurately. The outcome was a properly calibrated pressure gauge that met the required standards. Throughout the troubleshooting process, my technical skills, such as understanding calibration procedures and using calibration software, played a crucial role. Additionally, my analytical skills helped me identify the deviation from expected values, allowing me to adjust the calibration settings accordingly. To communicate the issue and outcome effectively, I documented the entire troubleshooting process in the calibration records, highlighting the steps taken and the final calibration results. By efficiently managing my time, I was able to complete the troubleshooting process within the expected timeline.

Recently, I encountered a calibration issue with an electrical multimeter while working as a Junior Calibration Technician. To troubleshoot the problem, I followed a systematic approach. First, I referred to the calibration procedure document to understand the expected accuracy and measurement ranges of the multimeter. Then, I conducted a thorough visual inspection, looking for any physical damage or loose connections. After ensuring the external condition was optimal, I connected the multimeter to a calibrated voltage standard and performed a series of measurements at different voltage points. The readings obtained were compared to the expected values, revealing a consistent deviation. To address the issue, I employed the calibration software, adjusting the calibration coefficients to align the measurements with the reference values. Following the adjustment, I repeated the measurement tests and confirmed the accuracy within the acceptable range. In terms of communication, I promptly reported the issue to the senior technician, providing all the relevant details and the steps taken to troubleshoot the problem. This allowed them to review and validate the calibration outcome. The final outcome was a successfully calibrated multimeter that met the stringent accuracy requirements. This exceptional answer demonstrates my advanced technical skills in electrical calibration, my ability to analyze and interpret measurement data, and my proficiency in using calibration software and computer applications. The clear and concise communication approach ensured an efficient resolution to the calibration issue. Additionally, my attention to detail and accuracy played a vital role in identifying the deviation and implementing the necessary adjustments.
