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

Applications   See more Applications > 

The PSA-24 has a very small input resistance of approximately 40 mΩ (±10A/±5A/±2A types), enabling highly accurate measurements.
It can also be used for current measurement of low-voltage devices and evaluation of charge/discharge characteristics of batteries and cell batteries.
