As-Found and As-Left Tests
An As-Found test result indicates the operating status of a device the first time you
test it. Immediately subsequent tests of the device are then recorded as As-Left
tests (unless the definition of the test is altered between tests, in which case a
different As-Found result will be saved). Thus, it is possible to have multiple As-
Found and As-Left Test Results for a single device. Typically, an As-Left test
reflects the operating status of a device after you’ve made any necessary
adjustments so that it will pass the test. (If multiple As-Left tests are performed,
only the last As-Left test will be saved and unloaded.)
Switch Testing vs. Instrument Testing
Switch (binary) testing may be performed with the 743 calibrator. Within
DPC/Track such tests are designated by "743 Binary" within the Test Type field.
When performing the test on the calibrator, select 1Pt. Switch or 2Pt. Switch as
appropriate. Conversely, instrument tests are designated within DPC/TRACK as
"702 Analog" ot "743 Analog."
Manual Testing
Not every device in your plant is suited for testing with a calibrator. DPC/TRACK
recognizes this and allows the manual entry of test result information. The
following steps outline the basic procedure for creating a manual test. (See also
Example 2.5.)
1. Access the Tag ID record (Instrument View screen) corresponding to the
device you wish to test. (See Chapter 3, “Searching for Records,” for
instructions on searching.)
2. Select the Test... button. The Test Selection screen appears.
3. Select the type of test you wish to perform, then choose the Continue button.
4. Enter the test information on the various pages. Note that each test type
requires certain data. (DPC/TRACK will prompt you for such information as
needed when you go to calculate or save results.)
5. After entering your test information, select the Calculatebutton (on the
Results page) to determine the Result, Max. Dev., Linearity, and %Error
values. (If necessary, you will be asked to enter any required information that
is missing.) Select the Save button to create and link the Test Results record
to this Tag ID record.
