Page 9: Precautions For Embedding The Device
2-2 Precautions for embedding the device This section describes precautions to be taken especially when embedding this device into a unit. Do not install the device in a place where air blows from an air conditioner. Weighing may become difficult due to the effect of the wind or the temperature may become unstable causing weighing errors. - Page 10 For accurate mass weighing, a warm-up of 1 hour or longer is required. The weight value measured right after power-on might contain an error. Do not use the unit until after warm-up is fully complete. Adjust the level of the installation location to ensure the weighing unit will be installed on a level surface.
