Fine – Tuning Final Target

This enables personnel to fine the final target.

1. Press the FUNCTION button once and Ft/F2
appears on the display.

2. Adjust final torque target by pressing
the +/- buttons.

(The torque can be adjusted a maximum of +15%
or –5% from the original final target).

3. Press the ENTER button and the display starts
to flash.

4. When a new final target has been found within above limits,
the DS Drive is ready to run that program.

Torque Tuning

This is used when a tool is controlled against an external torque
reference. If the torque value on the DS differs from the
traceable value, a Torque Tuning should be performed.

1. Perform a number of tightenings with the external torque
transducer connected, preferably 20 tightenings or more in
order to achieve a good mean value. Calculate the mean value
from the tightenings.

2. Press the FUNCTION button twice and tunE/F3
appears on the display.

3. Press the +/- button until you have the
external mean value on the display.

4. Press the ENTER button and the display starts
to flash.

5. Perform another set of tightenings to control your torque.

6. If the torque is OK you are ready to run. If not, do the
complete procedure over again.
