Calibrating the CT Analyzer

OMICRON offers a reference CT (calibration CT VEHZ0649) to verify the
calibration of the CT Analyzer. This reference CT is delivered together with a
calibration certificate of a national test laboratory.
The calibration CT has a ratio of 2000:1 and 2000:5. Its class is 0.02.
To verify the calibration of the CT Analyzer, it is necessary to measure both
ratios (2000:1 and 2000:5). The CT Analyzer is within the specifications, if all
measurement results are within class 0.02.
If the measurement results are not within class 0.02, we recommend to send the
CT Analyzer back to OMICRON for calibration in order to guarantee proper
operation in accordance with the regulations.
