SiglentTechnologies SDM3055 5.5 Digit Digital Multimeter, White/Grey

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.

Takes 30 minutes to warm-up for best accuracy but so does most precision electronics equipment so thats not unexpected.Extremely accurate, and just to put that into perspective.When measuring the voltage of a battery, you can watch the lowest digit drop as the capacity decreases from the high-impedance load of the meter.I got the high-end Siglent Arbitrary Waveform Generator too and WOW, this equipment is better than lab equipment costing many times the price.Siglent is a serious contender: - great packaging - great docs - outstanding supportYou can actually download the SERVICE MANUALS online,.. remarkable quality - like HP used to be.

I posted some pictures to help clear up some confusion on this meters abilities.MICROAMPSI read the MFG specs on micro amps, it reads like it only goes down to 200 uA. I should read the resolutionis 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.RESISTANCEYes, 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 READING4 Wire resistance testing, works great for me even with cheap kelvin probes, see photo's.INPUT VOLTAGE SWITCHYes, 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 LAMPYes, 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.

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

Excellent multimeter - precise readings and easy to use. Very satisfied with my purchase.
