–
Disconnect the cables (1) from the primary side of the transformer (2) and connect the
cables (1) to a 220 V light bulb (3) which is inserted to a socket. An ordinary desk lamp
can serve for this purpose. In case only 110 V light bulbs are available, connect two of
them in series.
NOTE
Be careful that no short circuit occurs!
After the cables (1) have been connected, plug the analyzer to the mains power again.
–
Set the power switch to pos. 3
–
Enter a weight manually (for example, 500 mg).
–
Press START
–
The word "Analyzing" should appear in the status window.
If not, but "Waiting for stability" appears instead, the reason is that after restarting the
device and the oxygen flow, the infrared base line is drifting. In order to save time, there
is a possibility to start the cycle without waiting for stability.
–
Quit by pressing STOP
–
Go to the "power user" level and click on the button "Stable".
–
The analysis cycle starts then without waiting for base line stability of the cells.
