Page 10: Intended Use
It can be used in UV curing systems, if the maximum operating temper- ature of 70 °C is not exceeded. For this reason, the UVpad is equipped with a thermal shield on the rear panel. The rear panel of the UVpad may be exposed to intensive UV radiation. The front panel must not be exposed to UV radiation. -
Page 11: Important Information
The maximum housing temperature can reach > 60 °C and there is the risk of skin burns on contact. Please allow for the UVpad to cool down and use pro- tective gloves to avoid skin burns. -

9 Operation 9.2.1 Start Measurement From the standby menu, a measurement is started with the key -key. The measurement device displays that a measurement is in progress. Stop the measurement by pressing -key. Turn the measurement device and position it for the measurement. 1. - Page 15 For optimal measurement results, the measurement range has to be fully modulated. For this purpose, the UVpad has a 12-bit analogue/digital converter, which scans the spectrum continu- ously. Excellent measurement results are achieved, when the measurement range is used to at least 50%.

Page 19: Information
Reset to factory settings 9.3.1 Sensitivity The UVpad adjusts the sensitivity automatically, in order to ensure the optimal signal-noise ratio. The sensitivity is hereby set via the sampling rate. With high irradiances, the sampling rate is increased in order to not exceed the measurement range. With low irradiances the sam- pling rate is decreased. - Page 20 This setting is suitable for most applications. In the setting „low“, the sampling rate is al- ways between 10 ms and 100ms. The UVpad can measure UV-systems with a very high irradiance or significant irradiance modifica- tions (e.g. with shutter operation or with very high tape speed).

The measurement time for the UVpad is set via the integration time. Typical integration times are 10 ms to 200 ms. If the UVpad is moved underneath an UV system at slow speed, then the maximum irradiance (directly underneath the UV lamp) is being determined, since several measurements are available for the irradiance. -
Page 30: The Uvpad Displays Too Little Irradiance Values
Furthermore, the UV lamps generally emit visible light and IR radiation apart from the UV radiation. Both can generate scattered light in the UVpad, which is then detected. It is also pos- sible that the UVpad heats up during the measurement and thus the reading noise increases. -
Page 31: The Measured Value Is Not Reproducible
11 Notes for optimal measurement results 11.6 The measured value is not reproducible Measurements are only stored and displayed in UVpad when the saturation is between 10% and 100%. This can cause to saturation direct under the light source, however correct meas- urement may be recorded before or after that. -

12 Cleaning, Maintenance & Troubleshooting 12.1 Calibration The calibration of the UVpads is checked during the initialization. If the UVpad is not calibrat- ed properly anymore, then this is indicated by a note after the initialization process. Measure- ments are also possible at any time with an expired calibration. -
