Testing and Calibrating the UV Lamps
The level of UV radiation from the lamps used for curing models can change over
time. To ensure optimum curing of models during printing, a pop-up message
reminds you to test the lamps and calibrate the level of UV radiation after every
300 hours of printing. You do this by running the UV Calibration Wizard.
To measure the UV radiation, you need:
• Stratasys TOL-03005-S (UV sensor and cable)
• a stand-alone UV radiation meter, approved for use with the printer
The wizard compares the measured radiation to the recommended radiation
level for each of the lamps, at each printing mode—High Speed and
High Quality / Digital Material.
When calibrating the lamps, the wizard attempts to adjust the radiation level, if
necessary.
• If the reading is within the acceptable range, the wizard continues to the next
• If further adjustment is necessary, the current phase is repeated.
• If the level of UV radiation is too low to be properly adjusted, the wizard
Before testing and calibrating the UV lamps:

continues to the next phase, but the final wizard screen indicates that the
lamp's radiation for the printing mode is unacceptable.
Make sure the glass lens on each of the UV lamps is clean. For easy access,
run the Head Cleaning Wizard, and use the special sanding sponge supplied
in the Start-Up Kit.
Make sure that the glass over the UV radiation sensor is clean.
