Out-of-Limits Reading
When a reading is out of limits, a # sign appears next to the reading with the
statement:
Out of limits . Both the high and low limits will appear. Whenever
this occurs, you can repeat the test or continue with the remaining steps.
Press
F4 to repeat the test or F5 to continue to the next step.
In order to flag a defib reading as out of limit, the reading must exceed the
programmed test limit percentages (
±) and differ from the expected step
energy value by more than one (1.0) joule. This out-of-limit determination
technique allows for a wider range of acceptable reading at the lower energy
settings which is typical of defibrillator specifications. For example, a
defibrillator can have a
± 50 percent tolerance at the low 2.0 joule (1.0-3.0)
which is covered by the ± 1.0 joule test limit and could have failed if only a ±
10 percent (1.8-2.2) test limit was used.
After the low range steps execute, you receive a prompt to set the Impulse to
the high range:
You can now execute the high range energy tests. These steps occur in the
same order as described above.
Note
You can skip an energy step by pressing the down arrow key on
the medTester. Whenever you do this, the energy reading line
displays the nominal value for the step followed by an X. Here's
an example:
ENERGY = 100.X J.
