What is a check standard?

Check standards are stable reference materials used to verify an instrument’s performance between calibration events. They provide a known, constant value so you can detect drift, bias, or changes in sensitivity as you use the instrument day to day. This keeps measurements可信 between formal calibrations and helps catch problems early. They aren’t about estimating uncertainty with random samples, nor about storing supplier contact information, nor about keeping a record of calibration history.
