| Time-specified logging, such as 600 seconds, is also available. Custom logger software is also available. | Multiple lists of set values can be compared and collated. | It prevents errors in note-taking and manual entry, and reduces management effort and costs. | Settings and confirmations can be made on the PC screen, preventing misoperation of the main unit's buttons. | Even multiple units can be easily configured by simply writing the configuration data. |
| USB Type-C connector standard | Setup unit without LINKSHIP or PC required: Program Loader PL-5A [sold separately] |
