8. Repeat until the angle accuracy and reset of the wrench are suitable to
the application.
NOTE
The default reset adjustment value for models 125, 250 and 400 is 4.
The default reset adjustment value for model 40 is 6. This has been set
on the basis of a balance between wrench reset sensitivity and angle
accuracy. Increasing the Reset Adjustment value will increase the
probability of angle error as well as the maximum allowable angle error.
The maximum allowable error will occur if the wrench is moving and
allowed to reset and the minimum speed is used during the tightening.
The table below shows the effect of increasing the Reset Adjustment
value on maximum angle error.
For highest angle accuracy results, adjust the Reset
Adjustment to the lowest setting possible, reset the wrench
while the wrench is resting on a table or other stable surface
and maintain a turning speed of between 20 and 80 degrees
per second. This will achieve consistent errors within +/-2%.
For applications where higher angle accuracy is required,
models EA40, EA125, EA250 and EA400 are recommended.
