Mounting hooks [Left and right] For fixing the main unit
Smart configuration and logging　 　LINKSHIP Page >　

Setting management, report printing, and CSV logging with dedicated software LINKSHIP [free of charge]　

CSV logging Compare and match set value lists PC save and copy of set values Prevention of misoperation Quickly set up multiple units

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:
