Smart configuration and logging
Setting management, report printing, and CSV logging with dedicated software LINKSHIP [free of charge]　 Go to LINKSHIP page

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: Setting, logging, power supply		Setup unit without LINKSHIP or PC required: Program Loader PL-5A　 [sold separately] 　 PL-5A Product Page *Setting only / data logging and power supply not available
Rear USB 2411 type also available.
