4. Chemical Resistance
If the product is used in an atmosphere with an organic solvent and other active gases, such as ozone,
ethylene oxide, acid, and al kaline, accurate relative humidity may not be achieved depending on the
level of concentration of the said chemical substance s.
Please consult with us if the product is to be used in such an environment.
5. Things to Be Noted in Handling the Product
Upon using this product, please take note of the following:
(1) Do not apply a strong force on the product.
(2) Do not leave the product under condition s that cause high heat, such as direct sunlight,
for a long time.
(3) Do not soak the product in water.
(4) Do not touch the sensor element directly with your hand. Use tweezers to attach/remove the
sensor element. Be careful not to damage the sensor element.
(5) Supplying voltage with a value beyond the permissible range may cause the product to generate
an erroneous output.
Make sure to keep the supply voltage within the specified range. Excessive supply voltage may
cause damage to the electric circuit.
(6) Do not bend the cable between the sensor and casing and the output cable to a sharp angle.
(7) Do not wipe the product with benz ene and thinner.
(8) Do not adjust or improvise the internal circuit. Doing so may lower the output accuracy.
(9) Prevent the protective cap from contact with other metal parts.
(10) It is recommended to calibrate the output once every few months using an accurate hygrometer.
(11) Install the product in a direction where TSM-H2/H3 with the current output specification will
not be affected by the heat generated by the electric circ uit of the main unit.
(12) Use only the designated AC -DC adapter.
(If option is selected)
6. Sensor Replacement
In case measurement accuracy is out of the specified range at Item 5 -(10), replace the humidity
sensor element
“
TI-A
”
in accordance with the following procedures:
(1) Remove the protective cap and pull out the humidity sensor module.
(2) Insert the new module into the socket section and attach the protective cap.
(3) Calibrat e the unit using an accurate hygrometer before using it .
