Thanks for the prompt reply Coen, Wanted to let you know that we re-ran the tests on 6 electrode sets (3 pairs) and found that the offsets were stable and variation within an electrode set was less than 10mV (no single electrode offset was greater than 10mV). We found that the "popping" during the b...

Thanks Coen that's very reassuring, perhaps we haven't ruined our electrodes! We have just started to do the bucket tests as part of regular maintenance on a number of electrode sets, both individual flat type (EXG) and sets of 32 pin type (with/without CMS/DRL). We noticed that initially the offset...

Salt solution problem

We inadvertantly did the bucket test for testing electrodes with iodized salt. Once we realised what we did, we immediately rinsed the electrodes with water and used regular salt but we can't seem to get the impedences down. Has anyone else encountered this, and is there any way to salvage the elect...
