Electromagnetic compatibility

This blood glucose meter meets the electromagnetic immunity requirements as per EN 61326-2-6 and EN ISO 15197 Annex A. The chosen basis for electrostatic discharge immunity testing was basic standard IEC 61000-4-2. Its electromagnetic emission is thus low. Interference on other electrically-driven equipment is not anticipated.

Performance analysis

Performance data for the Betachek C50 system was obtained using capillary blood from diabetic patients (method comparison, accuracy), oxygenated venous blood (repeatability) and control solution (reproducibility).

Calibration and traceability

The system is calibrated with freshly obtained capillary blood, containing various glucose concentrations. The glucose values used as reference values are obtained using the YSI method. The YSI method is traceable to a primary NIST standard.
Betachek C50 blood glucose monitoring system meets the requirements of EN ISO 15197 (2013).
Freshly obtained capillary blood is the only allowable sample. Results displayed are the plasma equivalent. See the instructions for use supplied with the test cassette for further information.
