Is it accurate when testing DC voltage and ohms?
Yes surprisingly linear but it's not easy to read you have to be looking at the meter right angle to be able to read the result. Please look at the spec sheet for accuracy.
I would expect it either to also work at 60Hz or to be switchable between 50Hz and 60Hz. Unless they have different models for different regions (unlikely) or just don't bother making it work at 60Hz.
I took time to test it at 60Hz this time at 30%, 50% & 90% duty square wave. Fluke 189 is showing a stable 2.9546v, the Uni-T UT71D is switching between 2.7xxx and 3.0106. At 50Hz both showing 2.9549v. I went to my friend's place and we tried his FG, same results. This is also same for triangle wave.
- There is no 'made in japan' written anywhere
I still have my original YX360 Sanwa AMM, its over 30+ years old and a real made in japan item, I use it as a general output voltage monitor. Since its entirely passive and uses no batteries except for the ohms range, I can leave it on all day, day after day.
It's made in Japan. Sorry I should have shown more pictures. Unfortunately this unit won't work without batteries.
If you don't mind, I noticed in this photo on the left, you have what looks like an HP/ Agilent 3610 or thereabouts, analog PSU, is this right?
You are right it's a E3610A. I will start a new review thread on the power supply. It's a versatile unit for electronics engineering. I like the small size of it, and love it for being linear. It's quite old so the caps started to leak and corrode the pcb tracks
. Fortunately my nose was sensitive enough to pickup the cat urine smell. They are now replaced with Panasonic FM and FC caps, I don't know if this changes the performance because it was working surprisingly fine when the caps was leaking!!

I also have a Philips PM2811 60W programmable switching power supply. It's a medium boat anchor. Love these Dutch made products very good engineering. I will post some internals pics if anyone is interested. Oh btw, the Hakko mod is also really cool, been wanting to share it, guess it's time to make lots of post.
