Iwatsu has released an interesting 6 1/2 count DMM, similar to the Agilent 34461A. Little information released so far. Has anybody played with this one before?
Possibly selling for about 1,100.00 USD in Japan.

Anyone have any further info on this meter? I can't seem to find much out from their website or even google. After Dave's latest video teardown I started to look at their meters and other items and found this post.

Here is a short video of the 7602:

Looks pretty sexy I must say.

Damn you Wytnucls! Now I want one and I have no need for it! The Iwatsu Catalog (page 36) has some nice info on the unit, looks really, really good for sub 1K price range.

Wow, $959 on TEquipment. Can Dave please do a review / teardown of this unit soon? :D
EDIT: On second thought, the 34460A is slightly cheaper if you don't need the high speed / internal memory. The Iwatsu's paper specs would suggest it's a much better value though.
-
Can someone give a blow-by-blow comparison of the spec sheets? I'm kinda interested in the logging functions.
-
Another video showing some of the functionality.

I just now punched the buy button. Christmas bonus gift to myself. :)

Nice! From Tequipment? I'm seriously thinking about it.
-
Yes, from Tequipment. We'll see how fast the unit is delivered.

looks really sweet. only 3A max tho? 80$ on tequipment.net for the lan module... hmmmmmm tempting...

I know, the 3A is kind of a bummer, also no capacitance. But I love the simulated analog sweep display and speed.
-
Would be good if it is possible for simple review on VOAC 7602. :)
I never had a chance to touch it.
-
Tequipment has notified me that the estimated SHIP date is 2/11/16, so my Christmas gift is now a birthday gift.
-
ever get your hands on it?
-
I've been busy and haven't had a chance to get to the multimeter. Here is a pic of it, I might get to test it in a couple of weeks.

Man, they sure did spend a lot on their graphic designer for the packaging! ;D Almost as much as Ersa!
Looking forward to your review in any case.
-
Interesting meter, perhaps a teardown coming? ;)
-
teardown & review please :-DMM :-+ :-+ :-+
-
Not that it means much, the packaging is all cardboard, double corrugated for the main box. Very well designed.

I've been using the meter today, working on a Sony V-Fet amplifier repair/refurb. Some observations from my time getting to know this meter:
I have no experience with other modern graphical UI meters. This one feels fast, very responsive. The functions are grouped pretty well, for example display options are all in one menu, I'll see if there is is more menu diving involved in getting advanced setups.
The display is very nice, sharp and clear. Buttons are also very crisp feeling, no mis-presses so far.
The construction seems up to current standards. The face is surrounded by a rubber material that feels OK as I place my fingers on it to push buttons with my thumb. The case feels solid, it does not rattle or make other noises.
The manual is on a CD, it is typical Japanese regarding the translation quality. You'd think after Admiral Perry arrived the Japanese would have better command of American English, it's only been 163 years since the American gangsters arrived. ( I am an American, and half Japanese on my mother's side)
I have been monitoring the bias setting of the amplifier, as this is a critical issue with the old Sony V-Fet amps. The Iwatsu provides me with a really good visual readout of how this circuit is behaving.
As I get to know this meter, I might add more info. I may also open the unit up and have a look around.
There is also a 7502 model, with fewer features.

nice meter, is it fanless?

Is it possible to see teardown pictures?

nice meter, is it fanless?
The case is completely closed, there is no fan. The more I use this meter, the better I am liking it.
The case has vents on either side, and there is a what sounds like a fan. It is very quiet.
I had another meter stacked on top, and looked at the stack in a dimly lit room. Apologies for my mistake. :palm:
-
When I am done with this project, I will open it up and take some pictures, perhaps next week if all goes well. :popcorn:
-
Please, do the teardown, finally. It's still the most modern-looking and sleek DMM on the market.

While trying to resurrect the topic - found series of high-quality photos from VOAC 7602: https://www.flickr.com/photos/ryuuoh/sets/72157668271935613/with/27737267623/ (https://www.flickr.com/photos/ryuuoh/sets/72157668271935613/with/27737267623/)
Top quality soldering, in my opinion. Have an itch to buy it right now =)

Perhaps this explains why the units have a LTC version of the reference with a HP part number on them
As you may be aware Yokogawa has built a lot of test gear for HP/Agilent and perhaps Keysight.
After reviewing the manuals it appears identical to the Iwatsu one I just bought on sale from tequipment.net
