Whilst every effort has been made to ensure that the accuracy of information given in this manual

is correct at time of going to print, the Draper Tools policy of continuous improvement determines

the right to change specification without notice.

This torque wrench is accurate to ± 4% of the set load and has been manufactured and tested in

accordance to ISO 6789.

Torque tools are classified as test devices. If a calibration routine is required, the calibration

interval shall be chosen on the basis of the factors of operation such as required accuracy,

frequency of use, typical load during operation as well as ambient conditions during operation and

storage conditions. The interval should be decided according to the user's procedures for the

control of test devices and by the requirements of the user.

If the user does not use a control procedure, a period of use of 12 months, or approximately 5000

cycles can be taken as a default value of the recalibration interval. For the first recalibration,

the period of validity starts with user's first operation of the torque tool.

In addition to these specifications, factory or legal regulations shall be observed.

The torque tool shall be recalibrated when it has been subjected to an overload greater than 125%

of maximum rated load and after repair, or after any improper handling which might influence any

errors in measurement.
