SBIG ST10XME showing constantly -152 degrees.

Dear all from SBIG TEAM,

Suddenly my SBIG ST10XME is showing in a permanent manner -152 degrees in SGP PRO..
is this related to any driver issue or to SGP ?

Permanent manner means, at the moment the CCD is turned on and SGP is showing the value -152
hence, the system is not cooling anymore..

And could it help ? if I provide to you any logs captures via SBIG DRIVER CHECKER ??
r do you think the matter is related to SGP ?

Any ideas are welcome.. few weeks ago, the correct values were shown in SGP..

SGP = sequence generator pro

Thank you

Martin

 

Thank you Doug,

I will try to find a copy of CCDOPS.. is there any special process I need to stick to ?
and one question, are the MaxImDLObsoleteDriver needed where the SBIG CCD is only
operated by SGP PRO ? I have this new LAPTOP and would rather only use the SBIG CCD with SGP PRO..

Do you think the OBSOLETE DRIVERS are needed to be installed beside the standard drivers provided with SBIG DRIVER CHECKER 64 ?? for the combination above ?

Thank you



Martin

 

Did find CCDOPS Ver 3.11B4, Nov 2011
hope the version is still good enough to make the functional test..

 

OK

Thank you Doug

Let me see if I can find one..

Cheers

Did find the version 5.61 from the STF product page..

 

Hello Bill,

here is the result from the CCDOPS and indeed, also CCDOPS shows -153.65"C

That was not the case last week.. when I did have the same ccd in action with MAXIM DL..

See the FIT HEADER from the DARK FILE taken last week.. it was still showing correct tempretaure values..

SIMPLE = T
BITPIX = 16 /8 unsigned int, 16 & 32 int, -32 & -64 real
NAXIS = 2 /number of axes
NAXIS1 = 2184 /fastest changing axis
NAXIS2 = 1472 /next to fastest changing axis
BSCALE = 1.0000000000000000 /physical = BZERO + BSCALE*array_value
BZERO = 32768.000000000000 /physical = BZERO + BSCALE*array_value
DATE-OBS = '2018-10-15T17:10:08' /YYYY-MM-DDThh:mm:ss observation start, UT
EXPTIME = 10.000000000000000 /Exposure time in seconds
EXPOSURE = 10.000000000000000 /Exposure time in seconds
SET-TEMP = -20.000000000000000 /CCD temperature setpoint in C
CCD-TEMP = -12.705067188926705 /CCD temperature at start of exposure in C
XPIXSZ = 6.7999999999999998 /Pixel Width in microns (after binning)
YPIXSZ = 6.7999999999999998 /Pixel Height in microns (after binning)


The ony difference between last week and today is.. I did only exchange the descicannt and that is it..and suddenly the CCD shows at the moment connected -153.65"C..and one more issue, I did also send the CCD to a friend " very well packed " since he wanted to use it and see how " GOOD " the CCD is.. " you know, many dream of having one SBIG ST10XME "



Is this a case which needs to be repaired by you Bill ?

Cheers

Hello,
thank you all (especially Martin!) for the fast and uncomplicated help. I´m the guy who is dreaming about having an ST10XME in the observatory
After all tries with with different drivers and software, i'm also at the point, that this might be an hardware issue.
Well, here at work, we have an electronics workshop. Repairs at this (and higher) level (Thermistor replacement) should be easily possible. But i would only try that check or replacmenet, when you (Bill) can give some instructions where the sensor is located and what type it is.

Another or may be related question according temperature: The camera gives also an environmental temperature. This value did also not change over the 2 hours yesterday evening. Always 25 degree, but it should read something around 19 degree. Is this a real measured temperature? Do you have any advice on this?

Cheers
Torsten

 

Thank you Bill,

I will contact you directly for the repair service.. I think I will do that..
the SBIG ST10XME is a very good ccd to leave it unused..

Still, very unusual, why one week earlier the CCD did work and then after sending it not " despite well packed ".. due to "open thermistor "
could that be due to transportation ??

Cheers

Martin

 

Happy Halloween Bill

Martin

 

Did send you email with questions..how to proceed to send the CCD to you for service..thank you

Martin
