Copy Fluke 87v power up options to 121GW?
« Reply #1275 on: October 22, 2018, 02:26:04 am »
This video explains power up options for the Fluke 87v.  It seems to me somethings like this would be easily implemented in the 121GW.

Useful options. But might be better if it is in some config menu. Otherwise it gets tricky, if you want multiple power-on functions.

Auto power off is inteligent in some meters , not just a timer . It resets itself if the reading is changing as you would measure something .
Anyway many other meters have at least some beeping sounds to warn you before the time is up .

Sigrock support for the 121GW was added:

This was done by a user of the 121GW, pretty neat.

Seppy, any word on why firmware V1.51 has been removed from the 121GW firmware list for download?
Is there a problem with the version or is it just missing after a website update? Need to know if the missing version has caused a problem and what the effect on the meter might be.

We don't think so, but there was an issue with one person. I thought it prudent to pause the update, looks like its safe I'll release it again when we are sure.
Their post on the forum is:
https://www.eevblog.com/forum/testgear/121gw-calibration-killed-after-firmware-update!/

They did not have a backup of their calibration prior to updating and seem to have bricked their cal, this has been investigated and at this point it it seems that their unit might have a physical defect or the cal was accidentally overridden by the user.

Odd that the link will not work here with https.

If there is anything we can do to help, just ask.   
How electrically robust is your meter?? https://www.youtube.com/channel/UCsK99WXk9VhcghnAauTBsbg

Seppy, I did not know of the need for backing up Calibration and installed 1.51.   I don't know if my Cal is bricked. How do I check?  What instructions did I miss about backing it up?

From your post, it sounds though like this one incident cannot be duplicated in house?

I ran a test where I checked several resistance, capacitance, AC/DC voltage, current ranges using the 1.0, 1.26 and finally 1.51.   At least with the prototype, the data does not shift (ignoring the changes to the filters). 

I also tried to repeat their test using 5.0VDC and 5.0VRMS 50Hz but saw no significant difference.

Android app:
I miss a feature to read/Export logs.
The gw 121 product page links to a UEi app, but the link is dead...
What is/was this app?
I did find a app named "UEi apps" , and in it, a  app "525DMM" is listed.
This latter app has a logs function and does connect to the 121 (shows error if bt is off on 121), but shows no measurements...
What is the Story here?

Temp sensor:
The 121 is rated up to 1350Deg. C. Or so. The sensor's insulation is obviously not, the Photo shows the effect of 1040deg. IT still seems to work, but I wonder What temp. Limit the fabric has, and What it is for anyways. The wires must be insulated different, but how.
And, What are the sensor's specs, in case i want to replace it?

There was no photo but I doubt anyone would  learn anything from it.  It's a K-type.  For higher temperatures, I have been using ceramics.

Hi Everyone,

I'm getting a little concerned with my order that I made back in September. I'm posting here as a last resort because the person I was in touch with, Suse, has not responded to any of my follow-up emails concerning the tracking of my order or a resolution. My 121GW was destined for Vancouver, Canada but the last tracking update was on September 16th when it passed through Germany: https://ecommerceportal.dhl.com/track/?ref=AUBCN001823543.

If you check the tracking yourself you'll see that it ghosted on me. Hopefully a little exposure in this thread will get some action or response.

Thanks for reading.

From the link that you  provided, your issue is with DHL, not with Suse or Jonestronics.   I am dumbfounded that you didn't contact the carrier back in September.

I followed up on this order on October 21st when I was told by Suse to email back in November if I hadn't received by then. I'm not the one arranging shipment so I don't think it's unreasonable to expect the folks over at Jonestronic to follow-up on their end. In my experience, when you purchase something online and it doesn't come through, usually the vendor is the one that has to follow up with the shipping company. Is this not your experience as well?

Edit: Just got off the phone with DHL, and just as I suspected, they tell me this is something that needs to be resolved from the merchant's side. I don't think your snark is warranted.

If it were me, I would work it with the delivery company.   I think your strategy is really more the cause of your problem than anything.  As your link demonstrates, Jonestronics provided the shipment to DHL.   DHL then lost it.

If you had worked this with your local DHL office, the problem would be solved. At the least they could admit that they didn't have the package anymore. Then their insurance would compensate you.

Now through your stuborness, the trail has grown cold.  Did you even complain to DHL?  I don't fault with Jonestronic's here.  I find it with DHL and your failing to complain they didn't deliver.  Nothing you have written is even remotely  relevant to anything I care about.  You have no issue with the 121 GW because, obviously, you never got one.  So please don't clutter up this thread.

Definitely down to the seller to sort out.

 :-+ I'm happy to take it offline, but I have to try other means if I'm not getting any communication. I understand things get busy.

It is the person that made the contract with the shipper that has to deal with it. DHL are not renowned in a good way all over the world. I tend to use different carriers depending on destination country.

This.

The merchant enters into a contract with the purchaser to supply the goods purchased.  The merchant then enters into a contract with the carrier to deliver it.

As I understand it, any assistance the carrier may provide to the purchaser is a courtesy.  Their obligation to deliver is with the merchant - and it is the merchant's obligation to the purchaser that delivery is made.

Thanks for the confirmation everyone! I’ve opened up a PayPal case as a last resort - hopefully it’s a little more visible.

I got mine delivered today. Ordered from Welectron and shipped the whole way by DHL. Pretty poor packing to be honest. The meter is fine and no bashes on the box so I take it it was handled well by the carriers, if it had taken a bump "en route" I doubt very much it would have survived. The fact it arrived unscathed was more down to luck than it being well packed.
