Hi DB Crew,

I just took my ohmeda 3700 on a holiday to Townsville and when I got here it doesn't seem to work properly anymore. I took it as hand luggage(boy did that raise a few eyebrows and require some explaining) which does mean it went through the XRay machine! On turning it on it asked me to recalibrate it to a 0 +-0.1 reading using the tiny pot screw on the bottom which I did. It acts as if it is working fine but the heartrate readings are erratic 37 - 220 bpm sort of stuff from one moment to the next. The saturation reading also seeming low with resting saturations of high 80s to low 90s....

Does anyone have any idea what might be going on??

.....we tried several sensors on two different people so it doesn't appear to be the person or the sensors but rather the unit itself


Having left the unit to "settle" for five days the problem is still present. I'd really like to avoid another purchase on ebay if I can, so if you have any ideas please let me know.
