instruments used can have a significant impact on operational efficiency and safety. Many engineers still rely on manual calibration methods to ensure their measurement tools are accurate. However, as technology advances and industries push for greater efficiency, it’s becoming clear that digital calibration tools offer a faster, more accurate alternative. Engineers working with strain gauges, load cells and pressure transducers are now being introduced to the benefits of digital calibration. Whether it’s the challenge of achieving precise output or reducing time spent on repetitive tasks, the shift towards digital tools is transforming how these tasks are approached.
By Rebecca Bentley, Senior Technical Sales Executive, Mantracourt How it’s usually done Manual calibration, oſten involving the use of screwdrivers to make fine adjustments, has long been the standard in industries where precise measurements are critical. Engineers familiar with this method know it inside out and there’s a level of control and hands-on involvement that comes with manually adjusting gain and offset settings. For many, it’s a process refined through years of experience. However, manual calibration can be

time-consuming. Adjustments need to be made incrementally, readings checked and rechecked and every small alteration must be verified before proceeding to the next step. While experienced engineers can manage this effectively, the process is not immune to human error and with increasing demands on time and resources, it's becoming harder to justify this slower approach.

alternative. By using USB-connected devices and calibration soſtware, engineers can now monitor and adjust settings in real time, with automated processes reducing the need for repetitive adjustments. One key benefit of digital calibration
is the ability to obtain instant feedback, allowing engineers to make accurate adjustments on the fly. Real-time data collection ensures that measurements are consistent and reliable, significantly reducing the chances of error that may occur with manual calibration. In industries where precision is critical, such as aerospace or automotive testing, these small improvements can lead to significant gains in both performance and cost savings. Moreover, adopting digital tools
enables engineers to future-proof their workflows. As more companies embrace digital solutions, keeping pace with these developments becomes essential for both efficiency and competitiveness.
