Overview

The CS110FV In-Field Verifier (Verifier) is used to verify a CS110 factory calibration. Housed in a rugged Pelican™ case, the Verifier includes a test cover that fits over the CS110 stator, a 12 Vdc alkaline battery pack, a GPS sensor to record the location of the CS110, and a CD100 keyboard display. A custom menu simplifies entering variables, initiating verification, monitoring the verification progress, and viewing the results.

Technical Description

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.

Specifications

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%
