Gas cycles
This function allows switching between two different CO
2
concentrations. Press the
Gas cycle
icon
to
set a gas concentration cycle (see Figure 41 a).

You can decide whether setting a new gas cycle (
New
, as shown in Figure 41 b) or loading a previously
saved one (
Load
). To set a new CO
2
concentration cycle, follow the indications below:
1.
Choose the two CO
2
concentrations between which you want to switch (
SP1
: Setpoint 1 and
SP2
: Setpoint 2,
as shown in Figure 42 a).
2.
Set the duration in hours and minutes you want the system to dwell on each concentration (1, 2 in Figure 42
b).
3.
Set the number of cycles (
Number
) you want the system performs (3 in Figure 42 b). Finally press

page will be displayed (see Figure 43 a). Press
Save
As
if you want to save the CO
2
Cycle program to be recalled for future experiments.
Note
►
You can save up to 4 different CO
2
Cycles programs. Saving a 5th one will overwrite the first one.
