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.

	Reset Adjustment Value	Models 125, 250, 400	Model 40
	Reset Adjustment Value	Additional Maximum Angle Error (% +/-)	Additional Maximum Angle Error (% +/-)
		Additional Maximum Angle Error (% +/-)	Additional Maximum Angle Error (% +/-)

	4	---	-4%

	5	4%	-2%

	6	10%	---

	7	13%	2%

	8	17%	5%

	9	22%	7%

	10	26%	9%

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.
