Testing Power Tools: 

1.  Application Method: Use a torque analyzer in “Peak Mode” with a rotary transducer between the power tool and the actual 

application. This is the best way to test since you are using the actual joint as the test station. You will see the actual 

torque applied to the fastener.  

Caution:

Variances in tool performance may occur do to the addition of the rotary transducer.

2. Simulated Method: Always use a quality joint rate simulator (run down adapter) with a torque analyzer when testing power    

tools in a simulated application. Use Joint rate and Breakaway methods to obtain most accurate torque readings in a 
simulated rundown. 

Care

1. The BFA-Series and NFA-Series screwdrivers are a precision torque control instrument and should be handled with care at all 

times.

2. Only use the transformers listed in the Mountz catalog or website for appropriate BFA-Series and NFA-Series driver model (If you 

have any questions regarding the appropriate transformer set-up, contact Mountz Customer Service Department).

3. Operate under safe conditions.  Do not place in operation where such objects as hair, strings, clothing, etc. can become 

tangled in the rotating bit.  

4. Keep away from moisture. Never use in high humid, moist or damp environment.
