CLEANING YOUR TRUZONE* PFM
Your TruZone* PFM should be cleaned weekly.
1. Soak the device in warm soapy water, agitating gently. Do not use a brush or other object to clean the
inside.
2. Rinse gently with clean water.
3. Gently shake out excess water and allow to air dry thoroughly in a vertical position.
4. You may also safely clean your TruZone* PFM using the normal cycle on the top rack of the dishwasher.
Cleaning with overly dirty dishes is not recommended.
CAUTION: Never disassemble your TruZone* PFM or place it in boiling water.
STANDARDS
The TruZone* PFM conforms to the American Thoracic Society Standardization of Spirometry: 2005 for
peak flow measurements. These standards reflect the use of 26 flow-time waveforms specifically selected to
evaluate peak flow meters. Accuracy is ±12% or 25 L/min, whichever is greater.
Note: The TruZone* PFM meets all accuracy and precision requirements that may be encountered under typical use. As with any
pressure/flow rate monitor, the TruZone* PFM may be affected by extreme altitude variations or temperatures.** The meter is not
significantly affected by relative humidity and should be used within a normal temperature range (20 to 35 degrees Celsius/68 to
95 degrees Fahrenheit). All measurements of the TruZone* PFM have been validated at Body Temperature and Pressure Saturated
with water vapors (BTPS).
