patterns where 1-8 will suddenly go from "railed" to "not railed" and, seldom, 9 through 16 will follow the same pattern.

I was using the 8 channel cyton board head gear and hardware settings which are default are not working for some channel. When the Input type is normal - 2 or 3 of the channels often are railed and wo

This is not so much the picked up noise that is my issue but the channel-to-channel discrepancy. Noise does not discriminate, it should be noisy everywhere or railed to 0 uV everywhere. Plus, my "

This led me to do a way simpler test: What signal do I have when absolutely nothing is plugged? All the channels of Cyton A are immediately railed and the signal goes to 0 uV except for the channel 1

I also tried to switch and use BIAS instead of SRB as it is suggested on Chip's website but it does not work much better. I get good GUI values in the low register but the FFT of the signal shows high

packet loss warnings/data streaming errors, railed time series channels, and poor impedance checks on certain channels even though all the electrodes are screwed in all the way. Hardware settings and

... I only have one reference earclip electrode but am missing one. Would that be the culprit? Also when I remove an electrode after it has adjusted and said 'not railed' it seems to still be giving t

I get an impedance value of around 4500 - 5500 kOhms when conducting an impedance test on the GUI. When I select 'live' instead I am able to get the channels to read 'not railed'. Not sure why the tes

before was fantastic at 3 kOhm. Also notice the railed/not-railed/near-railed conditions in the traces in OpenBCI GUI.

over these values, the output signal is "railed" or saturated hence constant: if you apply any high pass filter on a constant value, you get zero. Same input range constraints applies to ac

I am currently using the ThinkPulse sensors along with the Cyton board and WIFI shield. I'm encountering a situation where I need to adjust the hardware settings to PGA gain 8 or lower and Bias includ

Here is the section of GUI code that displays the Railed indications:

I use OpenBCI 8ch Cyton for EEG measurements. I received the "Railed error" in some measurement conditions. I understand this issue is caused by the electrode and connector. However, I have

This time all channels railed with BIAS, they are all 100% new electrodes. It's so hard to believe all new electrodes are malfunctioning.

Did you read the other pages on fixing 'railed'?

I tried with a larger range, as well as "auto", they are still railed. Any other possible reasons? Or any other check I should make?

'Railed' generally means that your signals are peaking ABOVE the maximum microvolts level set in the upper right on your time scale graph. Try setting a larger maximum. Most normal EEG is below 100 uV
