As other tests are done for this device, the results will be saved and sorted
according to their test dates, with the most recent test appearing first, followed by
the next most recent test as you scroll through the Test Results records. The Due
Date field will be updated automatically (if the test passed) by adding the testing
interval to the Test Date of the most recent test. So, if another test was performed
on this device on 3/18/96, the Due Date would be updated to 4/18/96, since the
interval value is one month.
Note
If either the Interval Value or Interval Units fields are not specified,
then the Due Date will not be updated when an associated Test
Results record is created. Passed “Manual Event” Test Results will
update the Due Date only if the associated checkbox within your
setup options is selected. See Chapter 9, “System Maintenance.”
Unscheduled Testing
With respect to device testing, unscheduled maintenance falls into two general
categories: “fix it when it’s broke” and impromptu. Of course, when something
breaks you must fix it. But proper instrumentation maintenance should minimize
this dangerous and expensive occurrence. An impromptu test is a valid
maintenance approach, though somewhat haphazard when relied upon too heavily.
Nonetheless, unscheduled testing can play an important role in the maintenance of
your instrumentation. It is possible to simply walk up to a device, test it, then later
unload the results into DPC/TRACK without even having to first load that Tag
ID’s parameters to the calibrator.
To help manage your test scheduling, DPC/TRACK provides the Test Scheduler
tool and the Mark for Load field.
