button to set up and run tests to verify performance of the instrument. Refer to page 301 of the Evo220 User Guide for complete information on performance verification.

The user must verify the performance of the instrument on a specified frequency. GEX recommends monthly verification, but performance verification may be conducted on a more or less frequency based on instrument usage, elapsed time, or to offset potential risks. Once the user has drafted the internal procedure for performance verification (PV), the user must conduct the first PV on the instrument in its installed location. Upon successful completion of such verification the instrument is ready for OQ. Operational Qualification (OQ): Upon completion of any and all PV activities, the user must verify the operation of the instrument. The user should verify the ability of the instrument to reproducibly perform fixed wavelength measurements. It is suggested to perform a gage R&R study for each dosimeter type that will be used. It is suggested to conduct thirty (30) repeated measurements of single dosimeters irradiated at low, middle and high doses in the user’s range, and to reproduce this test for a minimum of three (3) days. GEX has conducted extensive R&R testing - results available upon request. To complete these measurements, the user must use the Thermo Insight2 software. The protocol below must be followed in order to make fixed wavelength dosimeter measurements:

Protocol for dosimeter measurements using Thermo Insight Software: 1. From the Insight home screen, select “Fixed”.

PERFORMANCE VERIFICATION

Instrument performance should be verified at an interval determined by the user. Both Thermo Scientific and GEX recommend a performance verification using the Calibration Verification Carousel (CVC) on a quarterly basis. If using the Spectronic Standards instead of the CVC, a performance verification should be completed at least that often, if not more frequently.

CVC protocol:

1. First, performance verification is initiated by assembling the CVC carousel and motorized base.

NOTE: Both items must be assembled together before inserting into the Evo, otherwise the CVC filters will not be properly located in the Evo signal path.

2. The bottom of the carousel has an indexing tab that must be inserted into a slot in the motorized base.

PRECAUTIONS

Please refer to the Thermo Scientific Site and Safety User Guide for additional information and the full listing of precautions. NOTICE: Immediate exposure to room (ambient) air can cause condensation damage whenever the spectrophotometer has been stored or shipped. Move the shipping cartons to the installation location at least 24 hours before installation. This allows the instrument to equilibrate with the room temperature before the shipping cartons are opened and protective packaging is removed.

• Keep shipping cartons upright at all times. Damages due to improper moving techniques are not covered by the warranty.

• Connect the Evolution to a suitable uninterruptable power supply to minimize line current fluctuations that may alter

the measurement or damage the spectrophotometer.

• Keep the top cover closed and latched as much as possible. Minimize exposure of the spectrophotometer to airborne contaminants like smoke, dust, oil vapor, or chemical fumes.
