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)
or—
• 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 and 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 phase.
• 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
continues to the next phase, but the final wizard screen indicates that the
lamp’s radiation for the printing mode is unacceptable.
Before testing and calibrating the UV lamps:
l
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 cleaning pad
supplied.
l
Make sure that the glass over the UV radiation sensor is clean.
