What you can do with the controller management software
01
Fastening History Data Management
Maximum 40 million fastening history data collected from up to 10 controllers (80 tools) can be stored in one software.
Your PC doesn't have to be in the same place with the controllers when the PC and controllers are in the same local area network.
02
Fastening History Data Analysis
The worst 5 tools with the highest NOK rate or number of reverse fastenings (reworks) can be shown and you can easily find the bottleneck tasks. Trend changes in torque, fastening time, number of rotation in a fastening, and OK rate can be monitored over time.
03
Tool Status Management
You can record the usage history of the tools such as its start date of use, cumulative number of fastening works and latest repair date. Also, torque check history of the tools can be recorded as the evidence of the tool performance check.
