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 and switching the RH/T selection input, start reading after 800 ms or more as the output signal stabilization wait time.
- Use M3 pan head screws for mounting. Be sure to use a plain washer, and ensure that the tightening torque is 0.32 N·m or less.
- 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.
