content: Hello,recently I got the bench multimeter SDM3055 from Siglent. Now I want share some first impressions of this testgear.Like other Siglent devices, the first impression of this multimeter is not cheap. There is a fan build in which is not loud, about the same noise level as a Agilent DSOX3xxx.If you connect the device with line, immediately the green power led starts to fade in and out. The power button is a soft on/off button not a hard disconnect from the line.The probes are good quality but not so good as the probes of my U1272A. they comes with a pair alligator clips.the precision seems very good, if I compared it with my U1272A. I have already ordered on of the cheap Chinese voltage reference, so I can later compare it with this.One of the fuse for the 10A range is on the back side. Another fuse is build in inside the device.Internal the multimeter makes a well build impression, not cheap. As I can rate it, there are good quality components build in. The analog acquisition board is separated physically and electric from the digital board.The input terminals are protected, the RMS to DC converter ist extra shielded.

content: At the end some remarks about this testgear.Shuntresistance for the ampere range:1,2 Ohm for 200uA and 2mA1,06 Ohm for 20mA and 200mA0.044 Ohm for 2A and 10AThe input resistance is switchable between 10 MOhm and 10 GOhm but only in manual range modeThe voltage for the resistance mode seems high:1.05 V for 100MOhm2.215 V for 10MOhm5V for 2MOhm6.1 V for 200 kOhm6.84 V for 20 kOhm6.7 V for 2kOhm, diode and continuity testIn continuity test I can adjust the threshold.The GUI is mostly easy to use, but not so "elegant" like the GUI of Rigol or Agilent. One Point I have not understand it, ist the using and the advantage of the Dual function, here I have to read a manual or to experiment more. What I missed is a long time logging function to the internal or USB memory, so that I can use this DMM as a simple logger this is on my whish for that gear.I will using this DMM in the next week more intensive so I can write more about if it desired here.At last some screenshots:

content: Hello belba,and thanks for your review.As the price looks good this stuff becomes interesting. Please can you give us more informations? First at all about accuracy in volts and other measurement functions (if is possible can you test and compare it side by side with a certified tool ?), measurement speed, startup time, TFT viewing angles, display settings (change colours etc), printing of data, communication with software etc."What I missed is a long time logging function to the internal or USB memory, so that I can use this DMM as a simple logger this is on my whish for that gear." - What you mean ? How long is the maximum of this duration ?At the end you find this instrument a good value for money buying ?Also a small video it could be helpfull !Thanks in advance.P.S. Please forgive my bad English.

content: The screen shots look a lot like the Agilent 6.5 digit meter. Anyone have side by side pix?Wish I could find the Agilent at a slight discount, Newarkelement14 15% off is no good on it.Want good stability on a bench DMM, particularly with the trend analysis. How does the Sig fare in this aspect?

content: HiThanks belba for the reviewI'm looking to buy a Siglent SDM3055, that result is giving you ?, you could compare it to the Rigol DM3058E before purchase?Thanks for the info and sorry for my bad EnglishOsvaldoArgentina
