Caution
・
Before turning on the power, make sure that the AC power cord and the sensor cable have
been connected correctly, the sensor section has been set up, and an SD memory card has
been mounted.
・
When mounting an SD memory card, make sure that it has been inserted all the way in the
correct direction. Forcible insertion in the wrong direction may cause the card and this
equipment to fail. Any damage to the equipment due to this reason is not covered by the
warranty.
・
This equipment employs a small brushed motor so be sure to turn off the power switch and
unplug the AC power cord from the power outlet when measurements are not being made.
Continuously operating the equipment with the power on causes the motor brushes to wear
down. The service life of the motor is approximately 1,350 hours of operation.
Note: If this equipment is to be operated continuously for a long period of time, select a
brushless motor when placing your order. The results of our tests conducted under
normal temperature and humidity conditions demonstrate that the service life of
brushless motors is at least 10,000 hours of continuous operation.
・
If the motor on the sensor needs to be repaired or replaced due to its service life expiring,
contact the store where the equipment was purchased, or our service network.
・
If measured values are abnormal such as measured value exceeds the measuring range or
the dry-bulb temperature is lower than the wet-bulb temperature, "B.OUT" or "INVALID" will
be displayed. If this happens, restore the equipment to its normal state within the measuring
range, checking the situation of the wick and water supply, and checking that the terminals
have been connected correctly.
If the problem persists, the equipment may have failed. In this case, immediately stop using
the equipment and contact the store where the equipment was purchased, or our service
network.
①
Insert an SD memory card into the slot
Make sure that an SD memory card it has been inserted all the way in the correct direction.
②
Check that all the wiring is correct, and then plug the AC power cord into the power outlet and
turn on the power. The screen lights up and then readings will be displayed in approximately 10
seconds.
Note: If brushless motor is used, connect the AC adapter provided to the AC adapter port in
the upper of the sensor section, and set the power switch to the upper side to turn on.
③
Set the power switch to the upper side to turn on the power.
The ventilation fan starts rotating.
Allow the sensor to warm up for at least five minutes.
In particular, if the sensor has been moved from a place where
the ambient environment is very different, allow enough time for
the sensor to become acclimated to the
surrounding atmosphere before using the
sensor.
