View/Change the Pre-set Torque Value:

any changes. The target will show for 3 seconds.

2. Press and hold the Target - button to lower the current target value. Press 

and hold the  button to increase the current target value. The 
longer you press and hold the target key the faster the display will change.

When you apply torque with a target set:

As you get close to the target torque value you will see a yellow light 
warning you that you are approaching the target value.

When you are within 2% of the target value you will see a green light and 
hear a buzzer. Stop pulling!

When you go over 2% of the target value you will see a red light and hear 
an intermittent buzzer. Too much torque!

Changing Units:

1. Press the Units button to select different torque units: ft.lb.......In.lb.......Nm

Notes

: When you change units the target setting will also be changed to the

and on again.
