Note: 

*1: The accuracy of the readout is guaranteed from 

20% to 100% of maximum range + /- 1 increment. 
The torque accuracy is a typical value. Calibration 
point is at the middle line of black circle area on the 
rubber grip. For keeping the accuracy,calibrate the 
wrench for a constant period time (1 year). And the 
accuracy is based on the zero degree of offset from 
perpendicular drive. 

*2: Use two AA batteries (Test condition: Toshiba 

carbon-zinc R6UG battery) 

*3: Horizontal and vertical test 
*4: One cycle means swing the torque wrench from 0 

N-m to maximum range and back to 0 N-m. 

*5: Environmental test:   

a. Dry heat        
b. Cold    
c. Damp heat    
d. Change of temperature 

       e. Impact (shock)     

f. Vibration    
g. Drop 

*6: Electromagnetic compatibility test:  

a. Electrostatic discharge immunity (ESD) 

      b. Radiated susceptibility     

c. Radiated emission
