Hi,
You have wrongly connected the limb leads. Limb leads are those leads which we connect in the arms and legs.
In your case the leads in the arm have been interchanged. Thats why you get the message and prints inverted avR and avR.
check the leads and properly place it.
ok

Welch Allyn CP200 startup screen fine, then 3 beeps and screen changes to coloured bars. Reset button makes no difference. I note that the battery is missing. Is that the fault?


If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
I do recall that I've seen details about this ECG machine by the above site, long ago. Search for it by type in the brand name 'Welch Allyn'; in the search box at the top right of the Display Window of that site.

This has to do with where on the body the positive electrode is placed..in aVR the positive is on/near the right leg...a positive deflection, upright wave, is seen if the electrical activity, heart depolarization, is traveling towards the positive electrode...since the heart is rotated towards the left in the chest, normally electrical activity trends left...so in lead aVR the electrical activity is traveling away from the right so it gives a downward deflection of the waves

Welsh allen at-2 lead light is on however ekg machine will not give tracing


hi,
There is some problem with the patient cable. Any one of the lead is broken inside. AT2 senses the presence of all the lead first and then only it will acquire the ECG and store it in its memory,after that it will print the ECG.
If any one of the lead have some problem. it will not go to the next procedure. and will indicate the lead off light.

1. check are you connected the lead correctly.
2. clean the electrode properly.
then try one more time. if problem remains. you have to replace the patient cable.
ok

I just bought a unit AT2plus Schiller, and am having problems with the performance of the ECG. The ECG trace is getting too thick, making the visualization and interpretation. The change is seen in all...


There is a process for cleaning the print head. Try that first. I did a quick read of the manual, and it appears filters CAN be adjusted, but I would regard that as a last resort solution.

Also, adjust trace height (mm/mV) and paper speed to spread out the trace.

I have the Welch Allyn PCR 100 and have never been able to get it to produce an ekg even though I returned it and they had it working, when I hook it up it just doesn't work. Any suggestions?


Could be bad\expired electrodes, mislabeled lead wires and the patient cable is loose. Also, if one lead is intermittently working it may not show any leads on the report because that one lead is bad. If it is an intermittent problem it could work just fine for somebody else and not you. I can work on this for you if you need more help.
