Jan 30, 2018 · How often should instruments be calibrated? That is a question we get asked often. It would be nice to give a simple answer to that question, but unfortunately, that is not possible. Instead, there are several considerations that affect the answer of a correct calibration period. In this post, I will discuss these considerations.

Plant sampling on the site was almost systematic and for each species, twenty individuals were geo-tagged (Fig. 1b). Plants were at least 1 m distant from each other to limit the risk of confounding root samples from other plants. As the age of the individuals was unknown, only specimens < 2 m in height were selected to standardize observations.
imum voltage was calculated from the data for each aggregate using Proc Means (SAS Institute, Cary, N.C., USA). The maximum voltage was used to calculate the force applied to the aggregate at the point of fracture using the load cell calibration. Aggregate strength was measured on aggregates collected from nine irrigated ﬁelds in southern Idaho.
Observe the crossover of the calibration verification results and the line that represents the allowable limit for -0.33 TEa. Statistical criteria for acceptable performance: Linear regression statistics can be calculated and the slope compared to the ideal slope of 1.00.
