Connecting the Sensors

Connect the Sensor

*To avoid poor connections, be sure to push the sensor connector
securely into the jack.
* When using the temperature-humidity sensor in environments
where the temperature is 0 to 15 °C and humidity under 30 RH,
there may occur changes in measurement readings. This is not a
malfunction.
NOTE:
- If a sensor extension cable is being used with the data logger connected by
USB to your computer, electromagnetic waves may cause large errors in
measurements.
- For details about handling the temperature-humidity sensor, please refer to
page 6 "Cautions about using the Sensors" of "Safety Precautions and
Instructions"
