b. Record Information as follows:
Record the AR2 serial number and date placed in service in the assigned spaces.
Record the date of the test and the cumulative number of jumps in the assigned
blocks. The cumulative number of jumps is determined by taking the number of jumps
since the last test (obtained from the Jump Log Record) and adding this number to the
previous cumulative number of jumps. Note that when the unit is first placed into
service, the cumulative number of jumps will be zero.
Enter the result of each test in the assigned space as the test is completed. If tests
are repeated for any reason, such as an error in test procedure, record only the final
result, but be sure to also record the total number of actuations.
Enter the cumulative number of actuations in the assigned block. The cumulative
number of actuations is determined by adding the number of actuations in the just
completed test, together with any actuation noted in the Jump Log Record since the
last test, to the previous cumulative number of actuations. Note that when the unit is
first placed into service, the cumulative number of actuations will be the total number
of actuations completed in the In-Service test.
Note any unusual occurrences or conditions in the remarks space.
Enter the date and signature of the tester in the assigned spaces.
