User manual

In order to generate a valid new R-Curve for use by the QA-510,
you must work with a calibrated Pulse Oximeter unit or module,
a known good finger probe and a calibrated QA-510.
1. Launch PRO-Soft QA-510 on your computer and connect the
NULL-Modem cable from the COM port to the QA-510.
2. Turn on the QA-510 and the Pulse Oximeter.
3. On the QA-510, select through the different loaded R-Curves un-
til you find the Make that functions best on the oximeter in ques-
tion. (This will be the one that displays the closest correlation
between simulated and measured values.)
4. At this time you need to place the QA-510 into Remote Opera-
tion mode.
5. Within PRO-Soft QA-510, go to the menus at the top of the
screen. Select QA-510, then R-Curve. This will open the R-
Curve window.
6. In the scroll box you need to select the R-Curve data file that you
selected in step #3.
7. In the text box above the scroll box, type in the name for the new
R-Curve.
8. Now within the R-Curve window, select “File”, then “Save R-
Curve As”.
Do not select “Save R-Curve” or you will over write the data
for a currently calibrated R-Curve.
9. On the right side of the R-Curve window is a box where you can
select the memory position within the QA-510 to upload the new
R-Curve to. (The Default is the User-1 slot)
10. Press the “Make new R-Curve” button.
11. You are now in the R-Curve generation window. You will no-
tice that in the upper right hand corner of the window it will in-
dicate which R-Curve file you are currently editing. In the upper
left corner you will see two tabs; “Simple Mode” and “Advanced
Mode”. We suggest you start in simple mode.
12. The table on the screen is where you will set your test points.
This is done by selecting a cell in the “Simulated SpO2 Value”
column. To add more sample values to the table, right click
within the table and select “Insert Row”. We suggest testing at
99, 95, 90, 85 and so forth down to the lowest value that your
unit should properly display. (The more test points that you use,
the more accurate the calculated R-Curve will be.)
13. Once you have all of your test points selected, press the “Simu-
late SpO2 level” button.
14. Wait for the value on your SpO2 meter to stabilize then type it in
the selected “SpO2 Result” box and press “Enter” on your key-
board. This will send the next value to be simulated to the QA-
510.
15. Repeat step 14 until all values have been recorded.
16. Press the “Calculate R-Curve” Button.
