Changing or deactivating gradients
NOTE
Hotkeys
You can use hotkeys to call up the values for setpoint temperatures and setpoint
gradients directly instead of having to change them individually (⇨ "Changing the
Hotkey Settings", page 59).
You can change or deactivate the Gradient mode for the patient and cardioplegia
water circuit independently of each other. When Gradient mode is deactivated,
the device adjusts the output temperature to suit the setpoint temperature again –
without taking a gradient into account.
1
Touch the symbol of the corresponding circuit.
2 Touch the field with the value for the
gradient.
3 Adjust the value.
4 To deactivate Gradient mode, select the value [off] . To do so, touch the
symbol [–] until the field displays [Off] .
Or
To reactivate Gradient mode, touch
[+] until the touchscreen displays the
desired limit value.
5 To accept the changes, touch the [Confirm] symbol.
Or
If you wish to reject the changes, touch the
[Reject] symbol instead.
