7. Ambient Conditions and Calibration Check
Since important correction factors are calculated based on ambient conditions,
they should be checked at regular intervals. Incorrect or imprecise ambient
conditions result in measuring errors.
7.1 Ambient Room Conditions
At least once a day it is necessary to check the ambient room conditions.
This can optionally be done by the Ambient Sensor (Automatic Ambient Condition
Registration) or manually, if the system prompts the user to enter the ambient
room conditions (dialog box displayed below) when attempting to perform a
spirometry measurement on a subject.
7.1.1 Ambient Sensor (Automatic Ambient Condition
Registration)
The ambient sensor receives via bluetooth the following ambient conditions:
a) Temperature
b) Relative Humidity
c) Absolute pressure
1. Enter the current room temperature in ºC or ºF in the appropriate field. The
conversion of these units will be displayed as well.
A warning will be displayed if a value outside the normal range (17 – 34 °C/
63-93 °F) is entered. Please double-check to be sure this value is entered
correctly.
Once the MasterScope received the ambient conditions confirm these to proceed.
The ambient sensor must not be exposed to direct sunlight nor
positioned immediately near heating elements or aircondition elements.
In case of connection issues with the ambient sensor the ambient conditions can
be entered manually! Ensure to use ambient conditions from the room where
the patient measurement takes place! Barometric pressure must be taken from
the room where the measurement takes place! It is not allowed to take it from
the internet since this could lead to measurement errors.
