the dynamometer. Check the maximum hand adjustment. The maxi-

pointer more than one division before the clutch mechanism slips.
Readjust the clutch mechanism as required.
10. Apply five point calibration with the pointer and division mark aligned at
each reading.
11. Remove the dynamometer and shackles from the calibration standard
machine.
12. Verify the calibration data satisfy the dynamometer accuracy specifica-
tion. Enter the dynamometer serial number, the verified accuracy
tolerance percentage, sign, and date the certificate of calibration card.
There are four different main pointers for the AP Dynamometers (black). To
determine which pointer you need, you must know where the zero is located
on the dial. See illustration below.
