Tare key
Note: In order to prevent incorrect values for the contact force, make
sure that no force is acting on the cardiac wall when you press the Tare
key.
During insertion and positioning of the AcQBlate® FORCE ablation catheter
in the heart, the vectors indicating the values for determination of contact
force and the application angle are identified and transmitted to the
device. This means that values for contact force and the application angle
are already displayed before the actual cardiac radiofrequency ablation is
performed. It may be useful to set these values to zero prior to beginning
the cardiac radiofrequency ablation so as to better assess the applied
contact force and the application angle. The displayed values for the
contact force and angle are set to zero using the Tare key.
The device is automatically tared upon first connecting the AcQBlate®
FORCE ablation catheter to it and each time the Qubic Force is started.
When you disconnect the ablation catheter and then connect it again
while the device is still active, the values used to obtain contact force and
application angle are not automatically tared again.
The Tare key is located towards the upper right on the front of the device.
• Press the Tare key to set the displayed values for contact force and the
angle to zero.
