If the Bump Test fails, do not use the monitor until a successful Bump Test or Calibration
is performed.
6 Calibration
Calibration is the process of adjusting the sensor's response by using a specific concentration of
calibration gas. Sensors will drift for a variety of reasons, so it is important to perform a full calibration
periodically to ensure that the sensors response to the target gas are accurate. A full calibration consists
of two points, a Fresh Air Calibration and a Span Calibration.
Fresh Air Calibration adjusts the zero offset of the toxic sensor or sets the oxygen sensor to 20.9%
Vol.
Span Calibration adjusts the sensors response to gas to account for sensor drift. It is recommended
to perform a Fresh Air Calibration prior to a Span Calibration.
For O2 units: Initial calibration is performed on all devices prior to shipment. Once
received, calibration should be performed monthly (or quarterly) depending on
frequency of use.
All alarms are muted during calibration.
