Turn the Monitor on.
2.
Connect a calibration plug or temperature-sensing Foley catheter to:the
jack on the display assembly.
Note that there should be a temperature
reading in the Bladder Temperature window of the display (The readings
will vary depending on the air temperature as well as the F° or © setting
on the Monitor).
3.
Verify that there are no intermittent readings by gently moving the probe,
and pulling the probe out and plugging it back in several times.
If
intermittent readings are observed during this test, the temperature jack
must be repiaced.
