electromagnetic immunity of the device.

Do not put the device close to other devices or stack together. When necessary, observe the device closely to
ensure that it runs normally in the environment.

The device requires special EMC protection, and it is necessary to install and maintain it in the environment that
meets the following EMC information.

Even if other devices comply with CISPR emission requirements, they may also cause interference to this device.

When the input signal amplitude is smaller than the minimum amplitude specified in the technical specifications,
it may result in inaccurate measurements.

Mobile communication devices or wireless network devices may have an impact on the device.
