Configuring StO
2
Alarm Limits
StO
2
limits (both low and high) can be set independently for each channel. The default values
are 50% (low) and 90% (high), and any StO
2
reading outside that range will trigger an alarm.
The values can be adjusted if necessary.
Cautions:
Setting the Low Alarm limit to an extremely low value can render the Low Limit
detection ineffective.
Likewise, setting the High Alarm limit to an extremely high value can render the
High Limit detection ineffective.

Status area.
You can also, from the Main Menu, touch

and then touch

.
2.
Touch the button for the channel limit you wish to modify.
3.

Note:
For a given channel, the High cannot be set lower than the Low or vice-versa.
There must be a minimum 5% difference between the Low and High limits.
