CSV logging


Logging is possible by specifying the number of seconds. Custom logger software is available.

Compare and match set value lists


Multiple lists of set values can be compared and collated.

PC save and copy of set values


It prevents errors in note-taking and manual entry, and reduces management effort and costs.

Prevention of misoperation


Settings and confirmations can be made on the PC screen, preventing misoperation of the main unit's buttons.

Quickly set up multiple units



Even multiple units can be easily configured by simply writing the configuration data.
