Zero Calibration - Dräger Babylog VN500 Instructions For Use Manual

Performing a CO
2
Zero calibration is performed with a clean CO
sor which is removed from the cuvette. Zero cali-
bration is performed in ambient air.
CAUTION
The cuvette windows of the reusable cuvette have
different optical properties to the cuvette windows
of the disposable cuvette.
The cuvette type used must therefore be selected
on the Zero calib. on/off page. Otherwise the
zero point is shifted by up to 8 mmHg CO
Prerequisite: Babylog VN500 is switched on and at
least the three-minute warm-up phase for the
CO sensor has elapsed. After 3 minutes, the mea-

sured values will be inside the specified tolerance
range.
