YW-76-type and JT-1A-type simple stress meter in use found the following problems: 1. Probe leads to bring the exchange of signal interference; 2. Electrical 欠 design considered less weeks, resulting in decreased sensitivity; 3. Production use Some people in the process of failure. This article discusses some of the first two issues and proposes corresponding solutions.
