Hello and Thank you for All of your help in the past. I Have found out today that the counter that was sold to me is a GMC-500 and not the plus version the seller i purchased from on Amazon must have tampered with the unit as i see the 500 does not have 2 tubes yet this unit has 2 tubes installed it was sold as a 500+ unit but i have done another factory reset and it now says it is a 500 not the plus version so the seller must have put another tube in the unit and sold it to me as a GMC-500+ When in fact it is a 500 just with an extra tube that probably does not work

It is Not your Fault. But thank you for all your Help, i Purchased it from Amazon, so it will be covered for the free return and replacement.
Best Regards Simon.

EmfDev Posted - 06/27/2022 : 12:02:19
Thank you. Email sent for firmware. Please let me know if that works.
wiesner8 Posted - 06/27/2022 : 12:00:06
I Did a factory reset yesterday Morning thinking that it could be the issue but to no avail
EmfDev Posted - 06/27/2022 : 11:58:56
Before I send you the firmware, can you try to do a factory reset?

Indeed there is no tube selection. I already made the firmware because I suspect that there is wrong firmware downloaded but just want to make sure the serial number on my part is correct. Can you please double check the Main Menu -> About -> Model? and also Main Menu -> About -> Revision? Thank you so much!
wiesner8 Posted - 06/27/2022 : 11:22:12
Tube settings
tube voltage
high voltage display
HV Calibration
Tube dead time
EmfDev Posted - 06/27/2022 : 11:19:23
That is weird. What did you mean "It only say about tube"?

Did you see the Tube Settings Menu under Init Setup? Can you list the options under it? Thanks.
wiesner8 Posted - 06/27/2022 : 11:14:14
The wifi works fine it sends data and when i look on map it also shows the location and data but i see no option to switch tube
wiesner8 Posted - 06/27/2022 : 11:10:11
I Have looked at about and it say gmc-500+
Regards Simon
EmfDev Posted - 06/27/2022 : 11:05:52
Thank you! Can you double check the About -> Model and see if it is not the GMC-500+ version?
wiesner8 Posted - 06/27/2022 : 10:57:17
Yes i See a long black tube and a small clear tube
EmfDev Posted - 06/27/2022 : 10:48:37
Can you please email me the serial number under Main Menu -> About -> Serial number so I can check? And also please check on the back there are two windows to see the tubes. One is transparent and one is black. Do you see both?
wiesner8 Posted - 06/27/2022 : 09:46:06
And if it is a firmware problem how would i go about updating it
Many thank in advance Regards Simon.
wiesner8 Posted - 06/27/2022 : 09:29:27
Would this be a firmware issue ?
wiesner8 Posted - 06/27/2022 : 09:26:07
Yes but there is no option in the menu to select the other tube it only say about tube no selection
Regards Simon
EmfDev Posted - 06/27/2022 : 09:07:34
Have you read the user manual?

Tube selection is on Main Menu -> Init Setup -> Tube Settings -> Tube Selection.
wiesner8 Posted - 06/27/2022 : 07:32:11
To Be Honest with you i think i have been sold the wrong item is says GMC 500 + it has 2 tubes but no option to switch between tubes
Serial number is / 34193337333813
I Purchased via Amazon so i am now thinking of returning it as i dont believe i have been sold the correct item
Regards Simon
EmfDev Posted - 06/16/2022 : 08:45:02
