Important
•
Both the UIT-250 unit and the photodetector have individual sensitivity adjust-
ment controls. Do not touch these control; they are used for calibration by
USHIO only.
•
A very weak current flows through the UIT-250 unit form the battery even if the
power is off. Remove the battery when not using the unit for a long period of
time.
•
Note that if serial communication is used with the UIT-250 consumption current
increases and the batteries are consumed at a faster rate.
• If a separate-type photodetector is used, be sure to check that the model and
serial number of the photodetector unit match those of the sensitivity adjustment
adaptor. When changing the measured wavelength, you must change both the
photodetector unit and the sensitivity adjustment adaptor.
•
When using the temperature sensor, check that the model of the sensitivity
adjustment adaptor is UVD-TK.
• If there are particles on the photodetector or if it is dirty it can cause error in the
measurement.
Check to make sure that there are not any particles and that the photodetector is
not dirty. If it is dirty, wipe it with a piece of gauze soaked in alcohol.
•
When turning on the unit, prevent light from reaching the photodetector.
When the unit is turned on the exposure amount meter is initialized and the
irradiance value is set to 0. Therefore, if the unit is turned on while photodetector
is exposed to light the irradiance value is still set to 0. All measurement values
made thereafter will contain error (will be offset).
• If the irradiance exceeds the full scale degree of irradiance a scale over condition
occurs and the display monitor indicates the maximum value for the current
measurement range. Raise the measurement range to perform the measurement.
• If the measured temperature exceeds the full scale value, it is regarded as over-
scale and is indicated in the display monitor.
If the measured temperature drops into the temperature indication range, the
temperature is indicated again.
