Testing Protocols and Calibration Use Cases

​​​​​The first step in creating test protocols and calibration use cases is to define the mode you are testing. Load cells are routinely conditioned in either tension or compression mode and then calibrated. If a calibration in the opposite mode is also required, the cell is first conditioned in that mode before the second calibration.

​​​​​​It is important that the test protocol, which is the sequence of the load applications, is planned before any determination of possible error sources can begin. Typical error sources in force test and measurement are usually identified as being related to:

• Lack of protocol
• Replication of actual use case
• Conditioning
• Alignment
• Adapters
• Cables
• Instrumentation
• Threads and loading
• Temperature
• Excitation voltage
• Bolting
• Materials

If you are looking for additional references on testing protocols and calibration, our Interface Load Cell Field Guide is available to help. You can also check in with our calibration and application experts for technical support and assistance.

​​​​​​Understanding Uncertainty in Load Cell Calibration

​​​​​​One of the key factors of calibration and recalibration is understanding how to estimate practical uncertainty in load cell calibration. Each application is different in terms of its uncertainty requirement. It is critical to understand the uncertainty requirement on the application to ensure the force measurement device used is calibrated to handle the project. The first thing to understand when estimating uncertainty in load cell calibration is the GUM, a guide to the expression of uncertainty in measurement. Interface has provided a list of factors that will help guide you as you determine uncertainty for your application.
