シグレント(SIGLENT) SDM3055 デジタルマルチメータ ホワイト/グレー 5.5桁 【日本正規輸入品】

数年前から購入候補だったがなかなか手が出せずにいたけど、円安で軒並み値上がりしてて一瞬下がった時に購入。それでも3年前より1万円高い。よく使うのはトレンドチャート。レンジにより１桁多い７桁計測値が出る。3年前なら上位の3065xが購入出来た、残念。電源切ると設定がリセットされるのが痛い。 【230202追記】mAレンジはmath８桁表示nanoレベル迄出してくれる

I posted some pictures to help clear up some confusion on this meters abilities. MICROAMPS I read the MFG specs on micro amps, it reads like it only goes down to 200 uA. I should read the resolution is 000.01 micro amps to 240 uA the range threshold is 0 to 239 uA then range changes to mA at 240 uA as seen in pictures. RESISTANCE Yes, the continuity voltage is 6.4 volts and the resistance voltage is 1 volt. there was some concern about this damaging components. See the photos of the FLUKE 179's, they have an even higher voltage output . of 2.7 volts for resistance and 7.33 volts for continuity. I have never read a review questioning this on FLUKE. I have been using Flukes for 37 years and have never damaged anything with one. They have been an industry leader in test equipment forever. I think the Siglent will be ok too. SUB OHM READING 4 Wire resistance testing, works great for me even with cheap kelvin probes, see photo's. INPUT VOLTAGE SWITCH Yes, the power input switch is factory set to 220v, it also has a sticker over the power cord receptacle warning you to set your input voltage before you plug it in. BREATHING POWER LAMP Yes, the power led breaths in standby and is on solid when powered up. I like this feature because it reminds me to shutdown my power strip. The only thing I didn't like about this unit is the carry handle is cheap and it removes too easily. I can live with that for the money I saved.. Yes, the BIG name test equipment is better by far and is what I have used all my life, but for home or small business this equipment needs a look. Rigol and Siglent are two new names on my bench, to go with TEK, Fluke and Agilent, Remember they are made in China too. ;) Hope this helps.

Good lab type DVOM. Features 5 1/2 digits, trend & history charts, capacitor value finder, frequency counter, diode check, 2&4 wire resistance measurements, trigger mode, relative measurements, DC&AC amps 200mA -10A, math functions: statistics, limits, dB & dBm, limit tests. Analog filter, period measurements, overvoltage protection to 1000v, programmable screen saver and much more. If you want a good lab DVOM it is hard to do better. I was hesitating between this one and the Rigol DM3058 unit of the same caliber for slightly more money but the big yellow on black number display of the Singlent won me over.

Un gran instrumento de medición para laboratorio. Las gráficas son muy útiles cuando hago pruebas de consumo. Puedes medir voltaje y amperaje simultáneamente. Llevo dos años usándolo y ha sido una buena inversión.

I noticed some of the online reviews complained about the time it would take the meter to "settle", I don't really notice that. It does take a couple of cycles to set on a value but not a lot more than other meters I have used. For a bench meter, after starting with a VTVM (tube, as a kid in the 60s), this is by far the best I have ever worked with and for hobby electronics and casual design it is more than adequate. The display is easy to read and nicely setup. The power up sequence is slow for my taste, but it is computer, everything seems to take a while. Probably has Android or some variation of Linux underneath. Can't really make a comparison with similar brands in this price point, but I like what I bought.

New Siglent SDM3055 is a cost effective DMM which features a 5.5 digits accuracy. It has all the features built in for a low cost bench DMM usually found in a much expensive machine. The built quality is excellent and it has a new updated front panel. I enjoyed using it for daily work.
