Making Measurements
This Operators Manual covers specific measurement procedures in the following
chapters:
• Chapter 4: Checking Ventilator Parameters. Learn how to set up and take
measurements for the 16 ventilator parameters.
• Chapter 5: Measuring Pressure. Learn how to set up and take pressure measurements
using the High- and Low-Pressure adapters.
• Chapter 6: Measuring Flow and Volume. Learn how to set up and take flow and
volume measurements using the High- and Low-Flow sensors.
Working with Memory
Access Analyzer memory by pressing J. The following screen appears:

Press C or B to highlight an item, and then press E to make the selection.
Store all existing readings by selecting Save New File. The Analyzer prompts you for a
file name to Save As; use the text entry keys to enter a name. Then press E and wait
for a moment while the Analyzer stores the readings to this file.
Retrieve an existing file by selecting View File, scrolling to the file name, and then
pressing E. You can view the DEMO file in this fashion; it provides sample data for
all possible measurements.
Delete a single file by selecting Delete File, scrolling to the file to delete, and pressing
E
.
Delete all files by pressing Delete All and then pressing E.
Printing
Print data from the Analyzer using a PC running VT for Windows. This software also
allows you to view all 16 ventilator parameters on one screen and manipulate and graph
data.
Making a Measurement More Accurate
Warm-up and Zeroing
The Analyzer requires a warm-up period. A five-minute warm-up followed by a zero and
immediate measurement is adequate for most applications. A 40-minute warm-up ensures
maximum accuracy and stability.
The Zero Warn feature reminds you to zero the transducers at predefined intervals. Fluke
Biomedical strongly recommends that you leave Zero Warn ON and, after removing
pressure and flow sources, zero the transducers whenever the Zero Warn message
appears.
