Overseas Radio Wave Certification of Wireless Digital Levels

In this issue, I would like to introduce the radio laws in other countries. Nowadays, there are many wireless devices around us such as smartphones, wireless earphones, smartwatches, and game consoles, and I am sure that you are using one of them.

We also have two models of wireless digital levels. One is the domestic version, SELN-121BM, and the other is the overseas version, SELN-131BM. The accuracy and usability are the same, but why do we have two models? It is because each country has different radio laws! Have you ever seen the mark shown in Fig.1 ? This is a mark of technical standards conformity certification issued by the Ministry of Internal Affairs and Communications (MIC). This is the so-called “Technical compliance” mark. Use of wireless devices without this mark may violate the Radio Law. You can check the wireless earphones, game consoles, etc., so please check if you remember. In case of iPhone, you can check the logo of each country’s certification from General ⇒ Certification in Settings. Then, why are there such laws in each country? According to the Ministry of Internal Affairs and Communications (MIC) website, “Radio stations around the world are regulated by international treaties and the radio laws of each country. This is to prevent confusion in communications between radio stations.” It says. In other words, radio laws differ from country to country, so even if you can use a radio station in Japan, you cannot use it overseas.

Like the iphone, we have acquired radio wave certification for each country before release in order to be able to use it worldwide from the design stage, but we have adopted a method of acquiring electrical certification for each country in response to the demand. Since the demand was high in the U.S. and Taiwan, where there are many semiconductor equipment manufacturers, we started with two countries (Fig 5). In the U.S., the Federal Communication Commission (FCC, Fig. 2) and in Taiwan, the National Communication Commission (NCC, Fig. 3) oversee radio laws, and once certified, a logo and number are displayed on the product (electronic display is also available). In Japan, as mentioned above, the Ministry of Internal Affairs and Communications (MIC) is responsible for the certification. In Japan, as mentioned above, it is the Ministry of Internal Affairs and Communications.

Since we cannot obtain radio wave certification for wireless digital level meters by ourselves, we ask a certification agent to do it for us. The certification agent communicates with test institutes and organizations in each country to obtain certification. The process varies from country to country, with some countries allowing domestic testing of samples and others requiring on-site testing. Costs and delivery times vary from country to country, and depending on the number of units and costs, we may not be able to meet all requests. Please consult with us first.

In this issue, we have introduced the overseas radio wave certification of wireless digital level meters. We believe that wireless devices will become even more accessible in the future, and we hope that you will take some interest in them.
