RE: Troubleshooting ActivEEG problems

[Guest guest]

Mark:

I think a lot of these types of

problems are environmental emi type issues. Lights, cell phones, transient rfi.

You might try rebooting. I have found that the usb ports can become a little

unstable and sometimes uninstalling and reinstalling the wireless dongle drivers

helps too.

I don’t think you are the

lone ranger in what you are experiencing. The other thing I see is a sudden DC

offset in the signal. In other words the graph will suddenly jump up and then a

few seconds later jump back down. Again I tend to think these are environmental

type issues.

Hope that helps.

Subject: Troubleshooting ActivEEG problems

Hi all,

I’m having trouble getting a consistent signal recently and I

wanted to troubleshoot with the group. I’m using Pendants and ActivEEG

electrodes with BioExplorer. The problem, which has been intermittent but is

now getting worse, is that CH1 and CH2 indicators on the status bar of

BioExplorer will flicker on and off rapidly between red and green even with an

apparently good connection. I almost always have the green CONNECTED signal on

the status with little or no sync errors, so it appears the Pendant is working

fine.

This is happening with two different Pendants and two different sets

of ActivEEG electrodes. Sometimes you can switch Pendants or Actives or fiddle

with the wires or the position of the Pendant and suddenly the signal will come

good and CH1 and CH2 will stay green on the status bar. One set of Actives is

the earlier model and the other set is brand new and there can be problems with

either.

Today I tried every possible combination with each of my clients and

nothing would work at all. I switched to normal silver electrodes and no

problems at all. In trying to troubleshoot I tested using the older Active set

for active and reference on both channels, but then used a standard silver

electrode for the ground. That caused a permanent green CH1 and CH2 on the

status bar at first, but eventually started flickering. What I noticed,

however, was the red flickering occurred when I moved in the room or was close

to the client, but if I moved away and stood still I got the green CH1 and CH2

again.

The more I try the more confused I get. I’m ruling out a

problem with BioEx or the Pendants. Could it be a problem with both sets of

Actives at the same time? Or is there some kind of interference in the room? Or

both? What to do next?

Thanks for any advice.

Hey Mark ,

Is this whats happening to you? I don’t

use active leads so it may be interesting to see if anyone else has found a solution.

This happens everytime I hook up.

Hi Tony,

Are you referring to your attached file? I ran it but didn’t see

any of the channel indicators flashing on and off on the status bar, which is

what is happening to me. Normal electrodes work fine for me and the actives

usually do as well, just not in recent times.

Hi Mark,

Thanks for the advice. It really is hard to know if a transient

signal is involved, which is frustrating. It is also happening on my laptop at

home, so it might not just be the location.

Tony,

The flashing red CH1 and CH2 indicators most often suggest that you have a connection problem, NOT an emf problem (that's more likely to result in Sync Errors). Making sure your electrodes don't have spots where they are discolored, which may mean they are losing their plating, or that they have intact wires or that they are well connected to the scalp would be the first troubleshooting here.

Try doing a 1-channel hook up. Active at F3, on the scalp just outside the hair, reference at F4, same palce on the opposite side, so you know you don't have hair under the electrodes. Ground can go on the forehead. Make sure that F3 is plugged into the OUTSIDE RED plug on the Pendant; F4 is plugged into the BLACK plug directly beside it; ground is plugged into the green.

Try 3 electrodes and, if you get the blinking CH1, try switching out the electrodes at F3 and F4 with new ones. If you have access to an impedance meter, you can check them that way even more easily and see where the problem is in the impedance and offset readings.

Tony,

Tried to see what you are referring to in the session you sent. I saw 2 things: Your oscilloscope is set to re-adjust sensitivity. Unclick the auto sensitivity for each channel and set sensitivity at 30 and see if what yoiu were seeing goes away. Also, if you run the spectrum analyzer out to 60 Hz...you will see a definite set of peaks around 50-51 Hz. I'm thinking you are on the other side of the Atlantic??? and this may be electrical interference???

Thanks for the tip on the sensitivity. I

am looking into the 50hz thing, thought I had it beat, I am getting someone in

to have a look to find the source. Thought it was my fridge but no.

electrodes with BioExplorer. The problem, which has been intermittent but is

now getting worse, is that CH1 and CH2 indicators on the status bar of

BioExplorer will flicker on and off rapidly between red and green even with an

apparently good connection. I almost always have the green CONNECTED signal on

Actives is the earlier model and the other set is brand new and there can be

problems with either.

Today I tried every possible combination with each of my clients

and nothing would work at all. I switched to normal silver electrodes and no

problems at all. In trying to troubleshoot I tested using the older Active set

for active and reference on both channels, but then used a standard silver

electrode for the ground. That caused a permanent green CH1 and CH2 on the

status bar at first, but eventually started flickering. What I noticed,

however, was the red flickering occurred when I moved in the room or was close

to the client, but if I moved away and stood still I got the green CH1 and CH2

again.

The more I try the more confused I get. I’m ruling out a

problem with BioEx or the Pendants. Could it be a problem with both sets of

Actives at the same time? Or is there some kind of interference in the room? Or

both? What to do next?

Thanks for any advice.

Hi Mark

Was hooking up for a session and thought I

would try taking the extension off the wireless dongle to see if it made any

difference as I have Usb ports at the front  of my PC when I did this I got the

sync errors, when I put the extension back on the sync errors went away?

Hi Tony,

Are you referring to your attached file? I ran it but didn’t see

any of the channel indicators flashing on and off on the status bar, which is

what is happening to me. Normal electrodes work fine for me and the actives usually

do as well, just not in recent times.

Hey Mark ,

Is this whats happening to you? I don’t use active leads so it may

be interesting to see if anyone else has found a solution. This happens

everytime I hook up.

Troubleshooting ActivEEG problems

Hi all,

I’m

having trouble getting a consistent signal recently and I wanted to

troubleshoot with the group. I’m using Pendants and ActivEEG electrodes with

BioExplorer. The problem, which has been intermittent but is now getting worse,

is that CH1 and CH2 indicators on the status bar of BioExplorer will flicker on

and off rapidly between red and green even with an apparently good connection.

I almost always have the green CONNECTED signal on the status with little or no

sync errors, so it appears the Pendant is working fine.

This is

happening with two different Pendants and two different sets of ActivEEG

electrodes. Sometimes you can switch Pendants or Actives or fiddle with the

wires or the position of the Pendant and suddenly the signal will come good and

CH1 and CH2 will stay green on the status bar. One set of Actives is the

earlier model and the other set is brand new and there can be problems with

either.

Today I

tried every possible combination with each of my clients and nothing would work

at all. I switched to normal silver electrodes and no problems at all. In

trying to troubleshoot I tested using the older Active set for active and

reference on both channels, but then used a standard silver electrode for the

ground. That caused a permanent green CH1 and CH2 on the status bar at first,

but eventually started flickering. What I noticed, however, was the red

flickering occurred when I moved in the room or was close to the client, but if

I moved away and stood still I got the green CH1 and CH2 again.

The

more I try the more confused I get. I’m ruling out a problem with BioEx or the

Pendants. Could it be a problem with both sets of Actives at the same time? Or

is there some kind of interference in the room? Or both? What to do next?

Thanks

for any advice.

Here is the US you can purchase hand held Gauss meters for about $30 , perhaps there are similar models where you are ..???

Hi

Gee sounds like me, I was looking

yesterday at a site that somebody listed on here and it was $495 US I think. My

email is egg@... or grasshopper700@... if you

would like to send details. How about impedance meters while we are at it.
