Fluke 185 Review

<< < (11/17) > >>

DK ekectro:
 with modifying this dump file, the problem is that I can't change the label h01 to h02 ... I've tried several programming applications but I miss the last three column to display the address, so at the top of the program I only have; 0123456789ABCDEF columns, but I'm still missing these next three columns; 012, where in the end is the data needed for the modification ... Can anyone help with this problem ...? Thank you!

 :)All Hex editors won't have the same number of columns, it's just a question of display layout.
Look for address location Hex:600 no matter how many columns there are in your editor, if you're really as bad as I am for looking through hex files count back from an easily identifiable position such as start of serial number.
While you're at it could you please upload a copy of your original EEPROM contents if available? It could help understanding organisation for people in need of manual readjustment.

Edit: I figured you were using my memory dump anyway so if you really can't do the job with your hex editor, I can send you the modified file.

I have just received a Tektronix TX3 with a lowish serial number (<2000), F.W. version 0.0716. Funny thing about it is the back label is factory marked "DEMO NOT FOR SALE" above the serial.

Any other TX1 or TX3 owners noticed this?

shakalnokturn:
My two meters side by side comparing the modified Fluke 183's uncalibrated temperature readings to the long ago factory calibrated TX3's.

Note that the meters do have some differences, I prefer the plastics used and keyboard colours on the Fluke. The LCD is better on the Tek though.

I also noticed in the Tek that other than the spring contact there is a pogo-pin contact to the back shield near the relay, the pin is free to drop out and be lost (at the worse left floating in the DMM). I lightly squashed the end of the barrel on mine to hold it captive. As I remember it was already missing on the 183 leaving me puzzled to the purpose of the part at the time I opened it.

Hello everyone! First, I would like to very much thank the shakalnocturn member for the detailed description and presentation of everything he has done so far regarding this work on the TX1/TX3 measuring instrument. I believe that, like me, it helped everyone a lot. I bought a used TX1 but in very bad shape and with a UNCAL problem. Thanks to a member  shakalnocturn I made a complete modification to make the TX3 officially now... Everything works great except that there are deviations in some measurements, for example 80mV-100mV difference in AC and DC in all rankings, other measuring areas are not quite accurate either. Maybe someone has a very original dump file of TX3 so let me try it with him because the one that is currently in it is from Fluke 185. who knows...? I can live with that but after so much effort to paint the case again, polish the plastic of the screen, print the markings( it's not all over yet), I'd be sorry if some other instrument that was paid $20 in a supermarket showed more accurately than it...!
