Finally! Hantek HDM3065 6.5 Digit DMM

[SteveyG]

My first problem is that I have a Mac. So, I needed to install a Windows 10 Virtual Machine, and installed the software which I have downloaded from Hantek web page.

The first software you have to install and configure is "Keysight Connection Expert". It's included on the software pack from Hantek. Using the USB connection, it is easy to use. You can see the instrument immediately after running the software. After that, you can send commands SCPI commands, start IO monitor and, after that, you can run Hantek HDM3000 app, which is a "remote control" of the instrument, where you can press virtual buttons, and see the readings at your computer.

For LAN connection, first you have to connect your multimeter at the same network where is your computer, and configure Network Options at Utility / IO Menu. Insert a compatible static IP address, or use DHCP. Then, after you get the IP Address at instrument, you go to Keysight Connection Expert at your computer, then "Manual Configuration", and set the same IP Address. At "Set Protocol" section, select "Socket". You must use the default port 5025, and press "Accept". After some seconds, you should see the Instrument as you have connected using USB cable.

I look forward you get it running, but if you need, just call me here, and I can try to help more.

What USB driver are you using on your PC? I just get an error 28 - It enumerates as VID_049F PID_605E which is a Compaq device if the VID is to be believed?
RS232 seems to work fine, and it spoofs a 34461A if you change the SCPI protocol.

(edit: actually you can use Zadig to install the WinUSB and it appears in Keysight Connection Expert)

Hi,

I've just received a HDM3065.  Quite pleased with it so far, except...  I've noticed a bit of a problem.

Since I temporarily have an Agilent 34461A on my bench, I decided to measure the same voltage source (~29V) at the same time and see how the two tracked.  Pretty good until ~36 minutes into the test the HDM suddenly showed a measurement of ~53V.  And then every 36 minutes thereafter, the same thing.  Roughly 60V, give or take, rogue reading.  Makes a bit of a mockery of the stats!  The spikes are very definitely not real, as shown by the Agilent and also tested with a 'scope.

Attached are two screenshots showing the issue.  Note the spike to the right of the Hantek graph.

Same thing on current measurement, spikes every ~36 minutes except -ve going this time showing as '-ve overload', and 2W resistance - once again higher readings than is the truth.

This smells of software to me - but I can't seem to find any updated firmware on Hantek's website.  I see there is a thread on SW for this meter but haven't had time to digest it and my skim of it filled me with dread...

The software version is 2.0.0.6(2394081348), firmware is 04.01.07.04.23-02.05-21.

Has anyone else noticed this issue?  Or do I have a unit with a pretty whacky fault?

I've emailed support@hantek.com but received no reply yet.  This, I understand, is to be expected.   

Such a shame because the hardware seems pretty nice.


Cheers,

         Jez.

I can confirm that it's software related. I manage to reproduce and observe the same behavior.

Hantek sent me a firmware update but apparently it did not solve this issue yet. I will try to run more tests later to confirm.

Thanks for sharing, would you please your hantek contact info, because they did not answered their emails to me?

Thank you for this information.

Shame there is no fix...   Yet.  But at least I now know that sending it back for replacement is pointless.   

Do you know if Hantek are aware that this issue exists?


Many thanks and best regards,

         Jez.

I've never had problems getting a response from them by e-mail, I really don't now what happens. I now have direct contact with one of their representatives by Skype so it's much faster. I am not sure if I could share that, but I will ask.
For technical support, I would recommend that you first try to contact directly the seller from whom you bought the equipment, they should have easier access to Hantek's support, and contrary to what appears, they are very responsive and helpful.
I've also shared sometimes links from posts of this forum with them to see if they could help, but apparently, the moderator blocked their IP so they can't read the messages...

Do you know if Hantek are aware that this issue exists?

Yes they are, I reported it to them and they sent me the new firmware to test. I'll run more tests later and report back to them and see what else they can do.

That's very good to hear - thank you!

Fingers crossed...

Just got the new firmware for the HDM3065(B). It looks like Hantek have fixed the issue that caused a spike reading at ~36min of logging.

I've also attached the FW for the HDM3055 if anyone need it, but I don't have how to test that.

After applying the update the multimeter will reboot, but you'll have to turn it off and on again for the new firmware to be loaded.

[jezgb]

ETA:  Ignore me, I'm an idiot.  I didn't power cycle the unit after the software update.  Having done that, it is indeed fixed.  Thanks again!



Hi Microcheap,

Thanks for posting this - very much appreciated.

Sadly, it's done nothing for my 3065...

 


Cheers,

         Jez.

[Microcheap]

Did you turn off the meter after the update? The new firmware is loaded just after the next power on cycle.

[jezgb]

Yep - that's exactly what I (hadn't!) done.   

Thanks!

Thanks for sharing, I have updated my unit right now

Does anyone try add parts to get LXI?
Probably just RJ45 socket, ethernet transformer and some passive components needed.
Settings are available in menu and why not give a try.

So if anyone can do pictures of PCB with populated parts please share it here.

I saw the cal cert in SteveyG's video and experienced deja vu....

Yes, I did add the missing parts to my HDM3065 and it can connect to a LAN without problems.

You will just need to solder the LAN connector, a 1:1 LAN transformer, some 0603 resistors and 0805 capacitors. That's all, no other change in FW or HW is required. I have attached pictures with the components values for reference.

The process is straight forward, but you will need to completely remove the main board to solder the resistors and capacitor on the bottom. Just unscrew the top cover and the front panel for that.

Big thanks for your repply Microcheap.
Actualy I made some research and findout that there are instaled SMSC8710A LAN controller on display board.



Then I read manual and ordered some parts.



Your reply gave me extra confidence in my component values chouse so I wait for delivery and then I did it.

   

and it working.

      

My parts list:

R182,R183,R184,R185 - 49.9Ohm - 0603
R191,R192 - 75Ohm - 0603
R198,R199 - 300Ohm - 0603
C125 - 1uF - 16V - 0805
T2 - H1102NL
J4 - L-KLS12-108-8P8C-1X1-2-Y/G-0-01

Total price ~ 7$

I recently bought an hdm3065b, I used its usb interface, but it doesn't allow me to use the multimeter's physical buttons, in addition to the interface being slow, I wanted to know if there is a way to just transmit the image of the multimeter's screen to the PC for monitoring and maybe put In obs studio, I tried connecting via LXI through the browser but when entering the IP only some text information appears.

[k0st1z]

Please help. i add the missing components on an HDM3055. Now the both lan port lights blinking simultaneously every ~3 seconds. I added static ip. When i press dhcp i get an error. I tested with 2 different firmwares. And i cant connect the multimeter to the network. Any idea whats wrong ?

Over promise? Hantek has a consistent record of really attractive hardware and specs, but their software developers seem to let their reputation slip, holding back and delay potentially successful products. The HDM3065 was so delayed for nearly a year before it was widely available.

You sure that's not an April Fool's joke? 😉

[Simmed]

it would be nice for the HDMxxxx to post some noise results
especially the AVAR

Hello

Did someone has the latest firmware for the HDM3065B?
On the Hantek site there is no firmware updates!?
