Verifying Alignment And Calibration - COOK Medical Rhapsody H-30 User Manual

9. Once the "READY" bar is fully lit, the information bar will display "READY to lase. " This indicates
that the laser system is operating normally. (See Figure 4.)
10. Follow the instructions in the next section to verify alignment and calibration.

Verifying Alignment and Calibration

The laser system has been designed with many safeguards to prevent optical misalignment
during shipping and normal operation. However, it is important to verify the alignment and
calibration of the laser system to ensure optimal system performance. The following test requires
an energy or power meter calibrated to 2100 nm.
The following test applies to both 20 W and 30 W models. Note that some steps apply only to the
30 W models.
1. Set up the laser system for lasing.
2. Verify that the 550 μm test fiber has clean surfaces on both the proximal connector and distal
ends.
3. Insert the 550 μm test fiber into the laser aperture.
WARNING!
sonnel in the operating room must wear appropriate laser eyewear.
4. Set up the energy or power meter in front of and parallel to the distal face of the test fiber
establishing the measuring plane, as shown (see Figure 5). Be careful not to place the fiber
tip too close to the energy or power meter probe, as the energy density may damage the
detector's sensitive surface.
5. Set the power parameters to Short pulse width mode, 10 Hz and 0.5 J. (This step applies to
both 20 W and 30 W models.)
6. Press the ready button and wait until the information bar displays "READY to lase. "
7. Depress the foot switch for 5-10 seconds until you attain a stable reading on the energy or
power meter. If the reading is not within 10% of the displayed settings, the laser system is
either misaligned or out of tune. Please contact your sales representative or the Cook Capital
Equipment Service and Repair Center.
