1. Preload the wrench by loading the wrench three times in the direction of the test
(either clockwise or counterclockwise).
2. Set the pointer on the zero increment of the scale. The pointer MUST be set in the
same plane as the testing will be performed (horizontal or vertical).
3. Load the wrench until the scale reads at 20% of full scale (example a 100 in. lb.
wrench would be tested at 20 in. lb., which is 20% of full scale). Repeat the test 2
more times. Record all three readings.
4. Load the wrench until the scale reads at 60% of full scale (example a 100 in. lb.
wrench would be tested at 60 in. lb., which is 60% of full scale). Repeat the test 2
more times. Record all three readings.
5. Load the wrench until the scale reads at 100% of full scale (example a 100 in. lb.
wrench would be tested at 100 in. lb., which is 100% of full scale). Repeat the test 2
more times. Record all three readings.
6. Preload the wrench by loading the wrench three times in the opposite direction of the
test already performed (either clockwise or counterclockwise).
7. Set the pointer on the zero increment of the scale. The pointer MUST be set in the
same plane as the testing will be performed (horizontal or vertical).
8. Test the wrench in this direction by following steps 3 through 5. If all of the readings
are within the accuracy requirement no calibration adjustment is required. If they are
not see the section on calibration adjustment.
