• Always validate the O
2
concentration after calibration by performing several
measurements.
• It is not possible to calibrate the O
2
concentration in excess of +/- 3%. If you attempt to
calibrate the concentration more than this as compared with your starting point, the control
panel will display when you press the button and the up/down arrow
simultaneously. This e.g. means that if you have once calibrated the concentration by
+ 0.5%, the maximum O
2
increase during your next calibration will be + 2.5%. The
maximum O
2
reduction will then be - 3.5% (3% + 0.5%).
6 Operating the EmbryoScope time-lapse
incubator
The EmbryoScope time-lapse incubator has an integrated industry-grade PC running Microsoft
Windows. The PC controls all data acquisition functions, motors, camera, etc. The incubation
conditions (temperature, CO
2
and O
2
concentration) are controlled by an independent unit. The
incubation conditions are thus unaffected by software failures or failures in the operating system of
the PC. An audible alarm will notify the user in case of a software failure or a failure of the
operating system.
6.1 Start-up procedure
1. Turn on the EmbryoScope time-lapse incubator on the main switch (green switch at the
back of the time-lapse incubator, upper left corner).
2. From the incubator control panel, check that the temperature and gas set points etc. are at
the desired levels (see sections 5.4.1, 5.5.1 and 5.6.1).
3. Wait for the Windows operating system and the software of the EmbryoScope time-lapse
incubator to start automatically.
Once everything has been started and checked, you are presented with the welcome
screen.
