Technische Beschreibung

To test a CS110 in the field, the Verifier determines a CS110 MPARALLELPLATE calibration factor with an accuracy of 3%. This is done by applying measured dc voltages to a metal charge plate mounted close to the CS110 sense electrode and regressing the CS110 measured electric field against the Verifier applied electric field. If the test calibration factor differs from the original factory calibration factor (±1%) by more than 4%, the CS110 should be cleaned and retested. If, after cleaning, the difference is still greater than 4%, switch to the new test calibration factor (±3%) or return the CS110 for a factory calibration (±1%).

Each CS110FV has a unique factory calibration factor due to small mechanical variations in the Verifier test cover.

Spezifikationen

Factory Calibration Uncertainty ±0.78% (at a 95% confidence level)
In-Field Test Accuracy ±3%

The CS110FV factory calibrated uncertainty is 0.78%, corresponding to a confidence level of 95%. Therefore, when the CS110FV temperature is between 0 to 40°C, the CS110FV test accuracy is 3%, assuming a standard test uncertainty ratio (TUR) of 4:1.
In-Field Test Repeatability ±0.06%
