Cautions about using the Illuminance-UV Sensors
Do not connect the ISA-3151 sensor to any data logger other
than the TR-74Ui.
Use the sensor within the operating environment specifications.
When measuring ultraviolet light or other light which may cause
damage or injury to your eyes or skin make sure to use
protection such as safety glasses or some type of light-proof
shield.
Do not expose the sensor to a strong impact.
Cracks or scratches in the Illuminance sensor and/or in the UV sensor will
adversely affect the measurement accuracy. Also, a broken sensor may
result in injury.
This sensor is not waterproof. By all means do not allow it to get
wet.
Do not use in any environment that is exposed to corrosive gas
and organic solvents. Also, do not use in areas near fire or
exposed to excessive heat.
When the Illuminance-UV sensor is not being used, please store
it in a place with a normal temperature and without
condensation.
If the sensor surface gets dirty, wipe it with a soft cloth.
If the sensor surface accumulates impurities (dirt), it will cause a decrease
in the sensor’s accuracy and sensitivity.
If you wish to extend the length of the sensor cable, please
purchase our optional sensor extension cable separately.
Do not cut or process the sensor cables.
"Adjustment Settings" made in the supplied software are saved
to the sensor. Therefore, when a sensor is replaced, it is
necessary to re-make any desired adjustment settings before
using the new sensor.
Cautions about using the Temperature-Humidity Sensors
Do not connect the sensor to any data loggers other than
TR-74Ui.
Use the sensor within the operating environment specifications.
If extremely severe temperature changes occur, the humidity
measurements may appear abnormal.
Once the sensor's temperature becomes stable, the measurements will
return to normal.
This sensor is not waterproof.
Only use in an environment where there is no condensation or possibility
of becoming wet. Do not use in water or near areas where high-pressure
water is flowing.
Do not expose to condensation, dampness, corrosive gases, or
organic solvents.
When using the THA-3151 or THA-3001 (option) in an
environment where the humidity is under 30%RH, the
measurements may sometimes fluctuate. This is not abnormal.
When the sensor is not to be used for a long period of time,
please store it at normal temperature and humidity.
Continued use may cause a decrease in the sensor’s accuracy
and sensitivity even under normal operational conditions. If the
sensor is being used in a bad environment (smoky or dusty
places) it may be necessary to change the sensor sooner.
Do not use this sensor on the human body.
If you wish to extend the length of the sensor cable, please
purchase our optional sensor extension cable.
Do not cut or process the sensor cables.
"Adjustment Settings" made in the supplied software are saved
to the sensor. Therefore, when a sensor is replaced, it is
necessary to re-make any desired adjustment settings before
using the new sensor.
