Precautions during use

Precautions during use

  • To maintain accuracy of the sensor, recommended storage is as follows:
            Temperature Range: 10 ºC to 50 ºC
            Humidity Range: 20 % to 60 % RH
    Do not use polyethylene antistatic bags (light blue, pink or rose pink color)
  • The value of relative humidity depends strongly on temperature.
    When measuring ambient temperature/humidity, be sure that there are no components generating heat at or near to the sensor mountings.
  • When turning on the power, start reading after 100 ms or more as the output signal stabilization wait time.
  • Use M3 pan head screws for mounting. The tightening torque for the case should be 0.32 N·m.
  • Be sure not to bend the sensor cables in the vicinity of the sensor.
  • For other precautions, refer to “General Precautions” for temperature/humidity sensors.

*For other detailed specifications, refer to the specification sheet of the corresponding model.
