○  Double insulated electric wrench. 

○  Measures and indicates tightening torque.   

○  Tightening  torque  data  management  can  be  done  to  insert  the  microSD 

memory card into digital torque indicator.   

○  Reading  tightening  torque  data  and  measurement  time  stored  in  CSV  text 

format on microSD memory card on a PC. 

○  Tightening  torque  measurement  starts  automatically  by  installed  Auto  Start 

Mode. 

○  Automatically shut off when digital torque indicator is not in use for more than 

10 minutes.   

○  Notify the time of changing batteries.   

○  When a tightening torque that exceeds the maximum torque to be displayed on 

the indicator is measured, the display alerts that accuracy of tightening torque 
reading cannot be guaranteed 

○  Digital torque indicator turns 180 degree as below figure.
