Question about NRS SPO Medical 903036 Check Mate Pulse Oximeter
I have just replaced the battery in my Chckmate oximeter. When placing my finger into the monitor, I see the following: SPO, then a beating heart, then a pulse rate which is much higher than the actual rate, then a correct pulse rate, then with two dashes in the Oxygen level indicator and then almost immediately followed by 3 dashes in the pulse rate indicator. The back up light is working. I do not have the manual that came with this product so I don't know what the 3 various symbols at the very top, which appear, are indicating. Can you help??
Thank you. Blanche Matthews
OK - I had the exact same problem. I cleaned the inside of the oximeter with a cotton swab and denatured alcohol. Then tried it. It did not work. Darn. But I tried it an hour later, and suddenly, it started to work perfectly. I do not know what went wrong, and why it did not work immediately after cleaning. Maybe it was still damp from the alcohol? Unlikely, but I cannot figure out anything else. Anyway, try that and see if it solves the problem for you, and if the oximeter does not work for the first hour or so after cleaning, don't give up on it. Good luck.
