EEVBlog 121GW Discussion thread
matemathieu:
Hi,
I found it is not possible to report an issue on the store page here:
https://www.eevblog.com/product/121gw/
Hence have an issue to report.
According to the current version of the manual, the thermocouple reading cannot be calibrated.
One simple way of doing it is to use boiling/freezing water.
Capture the max temp when you put a K-type probe into your home boiler, make sure it does not touch the bottom where the heater is and you have the first point.
Water with ice would be the second one. Put water with lots of ice, wait. Make sure the probe end-tip does not touch the ice and capture the lowest value.
Is that a good idea?

How long does the 121GW take to load a new update, and how do you know when it has? Asking because I've just loaded the latest update onto a new high speed 68 gig SD card and it doesn't seem to have done anything in just under an hour! All the display is showing is IAP in the top left and down on the main display line.
I did everything according to the manual and advice above.

Situation sorted!!
I had a think and realised the file hadn't been extracted and the renaming hadn't worked properly. I renamed the thumbnail in the folder that I saved the new update to, but I didn't realise the file hadn't been extracted so wasn't actually renamed. Worked my way through that, dropped the SD into the meter, did the install key press thing, then I saw the download progress on the display bar graph! Ta Da!!
If the manual had mentioned what the download progress should be indicated by, I would have known there was an issue with the file on the SD!
So, meter now updated, all good! And the boot loader seemed to tolerate my ignorance fine!

I would expect the card to require Fat or Fat32 formatting, preferably done with the SD Association SD card formatter.
If your card is too large, it won't be Fat or Fat32 and the meter won't read it.

Possibly, I actually went back to the SD card supplied with the meter, which is 8GB. Thanks.
