That's a bugger about the mains supply on the 7555, it is noted in the manual in regards to the model prefix numbers and as we have now found out something to watch out for whereas some of the other models noted have selectable universal input voltage.

A link to the user manual page. it's on page 7 for the 7555.

That's a good looking meter! Gone is the odd angled input panel of the 7552. I like the large easy to read button labels. Looks like Yokogawa dropped the option of multi voltage operation on this series. I hope you get good use out of it. I love my 7552. It is an accurate and versatile meter. Do you mind sharing what you paid for the 7555?

I paid around 8050 yen ($99au), plus shipping cost me around $180 all in. I think exchange rate may have changed since last year.

The meter appears to work via step down. However throws an error indicating lithium battery failed. Looking into replacing that this afternoon.
Also on 4 wire mode, it shows overload. Possibly failed relay?

Some internal pics for you.

I just came across an Omega 7563 digital thermometer, which is a rebranded Yokogawa 7563. It is similar to 6-1/2 digit 7561 and 7562, except replacing current and AC ranges with thermocouple and RTD. The nicest feature is a thermally isolated enclosure in the back for connection of thermocouple with reference junction compensation.

The DC voltmeter is surprisingly accurate, within a few ppm as far as I can measure. It is also quiet for a 6-1/2 digit meter, with the last digit rarely changing. Another nice feature is high input impedance up to 20 V range. One limitation is that thermocouple temperature is only displayed with 0.1 degree resolution, while RTD is displayed with 0.01 degree resolution, they could have added one more digit.

Yokogawa 7563 was only discontinued in 2017, but my unit was made in 1992. It seems to use the same voltage reference SL161525 as the 5-1/2 digit meters. It was manufactured by National Semiconductor, but I also couldn't find any info, perhaps a custom part made for Yokogawa?
