The UIT-250 has an internal temperature sensor to protect the internal electric
circuit. If the unit is used in conditions that exceed the permissible temperature
range an overheat error (temperature abnormality) is set and is
indicated on the display monitor.
In order to reset the error, turn the unit off and allow it to cool naturally.
•
If is indicated on the display monitor, it is regarded as a battery
voltage error. This indicates that the battery level is low. Replace the battery. Be
sure to check that the power is turned off when replacing the battery.
•
The UIT-250 is provided with an auto-power-off function. If five minutes have
elapsed after an operation key is pressed, the UIT-250 is automatically powered
off. You can reset this auto-power-off condition by pressing the key.

This photodetector unit differs from the conventional photodetector models,
such as UVD-254PD, UVD-365D, and UVD-405PD, in spectral sensitivity and
angle characteristics. Therefore, note that it does not indicate the same irradiance
value as those models for a normal light source. When the UIT-250 is placed on
the conveyor of a UNICURE UV curing system, it indicates irradiance 1.5 times
larger than the value measured by UVD-365PD. This photodetector unit is pro-
vided with a large photodetector of 10 mm in diameter that is also able to receive
the light at an angle. Thus, it allows measurement for the accumulated UV amount
received by a radiated object (a workpiece) at high precision.
•
The sensitivity of this photodetector is calibrated using monochromatic light.
Multiple photodetectors of the same type provide the same indication for mea-
surement of designated monochromatic light - light sources. When the light source
emits a wavelength distribution take into consideration the spectroscopic sensi-
tivity characteristics of the photodetector shown in chapters 35 and 36 of this
operating manual. These spectroscopic sensitivity characteristics are representa-
tive values. When measuring a general light source that has a wavelength distribu-
tion, there is variability in the value indicated by multiple photodetectors of the
same type due to variability in the spectroscopic sensitivity characteristics of
the units.
