Finally! Hantek HDM3065 6.5 Digit DMM
<< < (15/24) > >>
Otso:
The continuity tester is much more sensitive on my Fluke 179 than on the Hantek, using the same probes on both.

Edit: That's because the Fluke beeps at < 25Ω and the Hantek at < 10Ω.

I got a HDM3065 for me a few week ago. It's just for hobby and I have used it occasionally only but I'm very happy with it so far.


--- Quote from: Kleinstein on April 04, 2022, 09:34:42 pm ---It is also odd to see only 1 string of the larger SMD resistors typical for protection.  I somewhat miss 2 more of those for the protection of the Ohms sense inputs. Unless there is protection on the bottom, I would be careful with the sense inputs.

I'm more curious than worried about any warranty so I opened my meter as soon as I got it and took some pictures of the PCB. The pics are not great and there's not much else on the bottom of the board but the missing resistors are indeed there.


--- Quote from: Otso on October 13, 2022, 07:23:21 pm ---- It's completely silent. The fan has never started, except on boot when it spins up (so I know the fan is functional). I value this very much and was one reason I bought this particular DMM, since I had understood that it is silent. Now I can leave it on without bothering me.

If I leave the meter on for long enough, the fan will eventually kick in. It works for a few seconds and then turn of again. It's a bit loud, but it is ok for me. My power supply and my DS1054Z are as loud or worse and their fan are permanently on.

I have no issue here. Check which settings your meter are loading during start up: go to [Shift]+Utility -> Store/Recall -> Power on
You can select the last settings used (that's how I set), the settings saved in a file or factory default.

I don't know with firmware version is yours but Hantek sent me some updates for the HDM3055 and HDM3065. Given the forum attachment limit I'll attach the files on my next post if anyone is interested.
Don't ask me which fixes are included. I've asked Hantek the same question and got no reply. At least, it did not break anything on my meter.  :phew:


--- Quote ---There's no manual for the SCPI commands, but I tested a few commands from a Keysight manual, and the ones I tested works. I got the VISA interface working on Linux. I would have hoped to get a simple USB serial interface, but that did not work out of the box, and I don't know how to configure it. If anyone knows, please share.

I also got the SCPI manual from Hantek (see attachments). I'm pretty sure it was available on their website but they must have removed it  :-//
I'm using the RS-232 interface of the meter with Test Controller to log some measurements.
There's no HDM30x5 option on Test Controller yet, but you can just select the Keysight 34461A on the device list and then change the SCPI command set on your meter to "Agilent".  ([Shift]+Utility -> I/O Config -> SCPI)

Regarding the user interface, I think Hantek, let's say, took an inspiration on the 34461A. I was watching and everything looks identical, except for some more advanced options that are missing on the Hantek's meter, everything else looks the same.
Looking at some pictures, even the layout of the components on the PCB are very similar on both meters.

To update the HDM3055 firmware, download the file htdmm55_V2004(2207081100)_20220708_R.zip.

For the HDM3065 use the file htdmm65_V2006(2208011137)_20220801_R.zip

Just extract the .up to an USB stick, plug it on the instrument and select the option [Shift]+Utility -> Test/Admin -> Firmware Update

In my HDM3055 the above firmware has been loaded. So far it works :) I didn't expect some new ones to be available so thank you for sharing.
After the upgrade:
"Software: 2.0.0.2 (2103131444) Firmware: 01.01.10.24.20-02.05"
 has changed to:
"Software: 2.0.0.4 (2207081100) Firmware: 01.03.06.01.22-02.05-02"

Yes, it's spun up for a minute or so when I have had it on for a long time. I don't find it so loud. I have an old Siglent SDG1025 waveform generator and that's what I call loud, and it's loud all the time. Really annoying. In the Siglent it's not actually the fan itself, but the vent holes that make the noise. I opened it thinking about replacing the fan, but when the fan is not close to the holes then the fan itself is quite silent.

That's how I have it. Still doesn't restore the button clicks to off for me. I'll update the firmware and see if that changes.

Edit: Updated to 2.0.0.4 from the file you provide. I have Utility -> Store/Recall -> Power On -> Last. Buttons still make the click sound after power on, even though I have them off before powering off. I, for example, changed the screen brightness, and that setting stays as I left it. But neither Beeper nor Key Click settings stay.

How do you check the firmware version? I would have expected it to be in Utility -> Test/Admin, but it's not there and the manual doesn't say anything about it either. And it doesn't show on boot.

Edit: *IDN? says I have 2.0.0.3. Still curious how to check the version on the display.

Edit 2: Found it in the help menu -> About.
