Posted 21 Mar 2023 Hi everyone, I am a newbie and I was trained that Omron DM is not retained memory and I think it cannot hold data incase power off. But in fact, I find that DM can hold data if power off even if I remove the battery. Anybody can explain me more clearly. Thank you Share this post Link to post Share on other sites
