∗1. Condensation may occur if the device is transferred quickly between locations with significant temperature differences. The device may not be able to measure humidity accurately if condensation occurs. If the product becomes wet due to condensation, allow the product to dry in a dry, room-temperature environment before use.
∗2. The device may not be able to measure humidity accurately if moisture is present on the sensor surface after being exposed to high humidity for an extended period. In this situation, allow the product to dry in a dry environment at room temperature and humidity before use.
∗3. Measurement precision may deteriorate due to the adhesion of impurities, contaminants, organic chemical substances, or other environmental matter on the sensor surface during use. Periodic calibration is recommended to check the measurement precision.
∗4. Long-term drift values are based on continuous usage or storage at a temperature of 25°C and a humidity of 20 to 60% within the warranty period of the product. Continuous usage or storage in an environment that exceeds these conditions may result in a drift value greater than the stated value.
∗5. Measurement precision deterioration may occur while the product is in storage. To maintain the original product performance, ensure a storage environment within the recommended temperature and humidity ranges. Storage in an environment that exceeds the specified conditions may cause deterioration of the measurement precision.

*1 Power saving mode. The indicator is always OFF in default setting. (Turns ON with button operation.)
*2 Automatically writes data to the SD card when reaching the upper limit of the internal memory and keeps recording
until the capacity limit of the SD card. If the SD card is not inserted when the internal memory reaches the upper
limit, recording stops. (Data can be output to the SD card by pressing the button after inserting the SD card.)
*3 This mode always records the latest measured values for the upper limit of the internal memory. (When the
measured values exceed the upper limit of the internal memory, the data items will be deleted beginning with the
oldest data item.)
*4 An alarm is shown when exceeding the upper limit value or lower limit value that has been set in threshold setting
mode.
*5 Nickel hydride battery and alkaline battery can be used. Manganese batteries cannot be used.
*6 Battery life differs depending on measurement environment, sampling, operating mode, battery type, or performance.
*7 The connector is type XW4B-02B1-H1, made by OMRON.
*8 When using a third party SD card, it is recommended to use a reliable and durable industrial SD card (SD standard or
SDHC standard (not compliant with SDXC standard), Class 4 or higher, flash memory type SLC or MLC type).
You must confirm the operation of the SD card yourself.
