Agilent multimeter from Japan
« on: January 21, 2024, 11:55:16 pm »
I’m bidding on eBay for an Agilent multimeter, and I just noticed that the seller did write this on the description:
"The voltage of the electronic device on display is 100 VAC, a Japanese product. If you use the voltage in your country, we recommend using a transformer."

Now, on the back of the MM (34401A) I see a lot of voltage listed and a small window with "100" inside : given I live in EU with 220V, should I retire from bidding or the seller was overzealous and the voltage can be easily switched to 220 ?
Anyone with experience on this ?

Edit : found MM manual. It seem that the fuse holder assembly can be rotated in order to show and match the proper voltage…what about the fuse itself…given the pic, it looks like it must not be replaced…

If that photo is of the actual unit that you are buying, you should be good.  If not, you might want to verify that the back of the auction unit actually looks like that.
A 3.5 digit 4.5 digit 5 digit 5.5 digit 6.5 digit 7.5 digit DMM is good enough for most people.

That’s the actual unit I’m on… thanks  :-+

On the 34401A the line voltage selection is done via pulling and rotating the fuse holder assembly.  The manual says to use the 250mAT fuse for all line voltages (100,120,220,240V).
On the 3478A (I happened to recently buy another one from Japan), you have to open the unit up and move an internal wire to change the transformer winding.

The important thing to remember is don't turn it on, take it apart... and check the capacitors and line voltage setting before first power up.
Being in Australia, I've had to handle this on multiple pieces of TE coming from USA (not so much for EU).

for sure  you need to change the fuse assembly to select the right voltage ...


on you purchase picture do you see the unit working ???   the vfd brightness ??  if not stay away

a blown xformer    is around 75$ usd,  a vfd is easily 130$ usd      ....  serial number will show  if you have the old unobtanium vfd drivers who does over the years  mostly    the red only plugs      or the latest  model   with black and red plugs

you have to check the sn range   to get witch pcb version you have

Assuming that the OP's title is correct and it is actually an Agilent-branded unit, none of those things should be an issue.
A 3.5 digit 4.5 digit 5 digit 5.5 digit 6.5 digit 7.5 digit DMM is good enough for most people.
