The cheap goods of testers, such as made in China, flooded, and I have not bought most of the Sanwa Tester products here for 20 to 30 years, but the Sanwa Digital Multimeter I bought this time was a promising product. First of all, I think that it is a product design that considers usability very much, I think that there is almost no difference in function compared with inexpensive goods, but perhaps it is perfectly designed and produced in a place where consumers do not notice. For example, safety design in case of misoperation etc.

Voltage and Continuity Check

I have used Sanwa's pocket type (PM - 7) for many years, but since I no longer display the liquid crystal even when I changed the battery, I bought this model that can use AA batteries. What I was most surprised when it arrived was "deck!" I am satisfied with making it sturdy, but I am satisfied if it is about two times smaller. Accuracy We do not know because there is nothing we can compare, but I am not worried at all. I think that this time it will be available for 20 years.

* I will make a state that is easy to see by using covers, but I want you to make a fuller confirmation of the fulcrum. * Since I have been using analog for decades, it was fresh that it was not approximate when I showed a numerical value. * Continuity test buzzer is useful.

Voltage, current etc. various measurements

Because it is a case type, it is convenient to carry. However, since the case is rounded, it becomes unstable when it is stacked with other tools. I think that it was still better if it was a square. Measurement accuracy is as per the catalog specifications, and the dial for the larger eyes is also easy to use.
