By this do you mean how do we set the initial calibration for a commodity or how do we calibrate an instrument when it’s back for service or repair?
If it’s the former, then over the last 20 years or so, each harvest we’ve collected samples of all the commodities we measure with our meters and oven tested them. The results of these tests are then used to adjust the programming within the meters to make the results you get more robust with time.
If it’s the latter, then firstly we calibrate the hardware to ensure that the mechanics and the electronics are performing to their specifications. Then we check that the moisture results are within specification against a range of known calibration standards. Finally we put each instrument through a final check procedure with a different set of oven tested, calibration standards to confirm the calibration.
There are so many interesting aspects to what we do that we though our customers might like to hear about some of them. Check out our newsletter to read about what the team have been getting up to.
