Is it dangerous to install an electric meter on a hot wall and be heated by the sun?

Excuse me, do you want to ask, "Is it dangerous to install an electric meter on a wall heated by the sun?" There are some potential dangers in this practice.

Here are some possible questions:

1. overheating: if the instrument is exposed to high temperature for a long time, it will lead to overheating of the instrument. Overheating may damage the blood glucose meter and even cause a fire.

2. Power failure: Direct sunlight may cause the temperature around the meter to rise, thus affecting the accurate reading of the meter. This may lead to inaccurate energy bills.

3. Electrical failure: The high temperature environment will adversely affect the electronic components and circuits inside the instrument, thus increasing the risk of electrical failure.
