Hi Jerry,

Will do!
I'll forward this & your request directly to Mark P right now, as I just read your post & I think it's a great idea.


P.S. Yep, I'm one of several moderators. {;-)

P.P.S I forwarded the request to Mark @ 12:33am by email.

FYI, I tracked the actual manufacturer of this meter to Uni-Trend.  It is the UT322 click here.  Unfortunately, they don't have any software downloads for it.

The most recent Windows XP update broke the 72-7712 software (crashes before starting).  Uninstall/reinstall doesn't help but rolling back the Windows update does.  MCM sent me a version 2.0 of the software (latest they have), but it also crashes.  I sent the crash reports to Microsoft.

Until it's fixed, I'll just use the software on an old junk pc that I never update.

Dan, I have WinXP 2002 (Home) Service Pack 2.  I have auto-update running and have all the current updates.

I am experiencing no problems with the software.  No crashes on bootup.

Could it be something else?  An issue around resource allocation?  An HD that needs to be de-fragged?

I wish I were a better expert;  I am just a good 'appliance operator'.

Is anyone else having similar problems?

My laptop has XP Home SP3, and it was the Jan update that caused the problem (rolling back fixes it).  Don't really use it for much, but everything else seems to still work.

This probably won't help anyone else, but I wrote a Linux program that dumps the 100 stored samples over USB just like the windows program, and saves it in CSV format.  If others run into this problem, and if there's no official fix, maybe a Windows programmer can port my program to Windows and make it pretty...

Windows XP, Windows Media Edition 2002, service pack 3 = no problems here.  Auto updates turned on.  Still running fine on my end.

Dan, let me give you an 'Appliance Operator's' trouble-shooting tip:

Find a buddy with WinXP (home) 2002 Service Pack 3 installed.  Ask him to install the program and see if it opens ...or crashes on startup.  

Your buddy should NOT have a laptop.  My experience with laptops is that they are more troublesome in the way they use resources (or something (...that means I don't exactly know what I'm talking about)).  But seriously, my old Toshiba laptop had problems.

Let us know.

Do have a question with this unit that Jerry probably hasn't experienced.  I will actually read the manual but my unit is auto shutting down about the 90 data point being entered.  I don't see a low battery level light on, but I am just missing the last few data points from being entered.  I thought that it was shutting down the back lighting but the last two roasts have missed data points because of this.  Again I am logging every 11 seconds so that roughly translates into 16 and a half minutes into the logging.  My roast don't go quite this long but I like to log the chamber heat up and subsequent drop in chamber temp when I dump the beans as well as the turn point (how low the chamber temps go before they start to climb again).  The reason that I said that I didn't think that Jerry has experienced this is that he doesn't log that long, but maybe it isn't a time thing, maybe it is something else.  I will change the battery before I log the next batch today.

I had the sleep mode turned on and once it goes to sleep it stops logging.  Make sure to set it long enough in the set up file to take you to the end of your roast/logging session.

Hi,

Thanks for the information, I got mine today. A few newbie questions:

1) There is a 50 or 60Hz frequency selection in the setup. What is it for? The manual does not mention any details on this.

2) The K probe I received has a small black rubber sleeve at the tip? Won't it melt at high temps of 450+? Should I push it back or remove it?

3) Will the white/blue sheath withstand 450+ degrees? Should I remove part of it and expose just the metal wires?

4) SC/TO users: How do you mount such a probe for measuring bean temperature without getting in the way of stir rod?
