| Siglent SDM3055 vs. SDM3065X |
| (1/3) > >> |
| ElectricPower:
I allready have two good handheld multimeters. Brymen 869S and EEVblog BM786. But i really want an good Bench multimeter with same or better resolution and accuracy then my BM869S. I have pointed out Siglent SDM3055, but i know SDM3055 also has an bigger brother with name SDM3065X. Yes, the resolution is higher and accuracy, but iss there other reasons to buy SDM3065X instead regards to price? |

SDM3065X has a few extra fruits but the main difference is the higher accuracy due to its LM399 Vref whereas SDM3055 uses a MAX6325 Vref. Size comparison when I had all 3, the 3055 mid stack was an early unit before the horned bumpers were added later. Datasheets reveal the other differences. ;) |

| Kleinstein:
The SDM3055 is better accuracy, at least in most functions/ranges. In some case by quite a bit, like with resistance and lower currents. With different ranges there may still be a few point where the Bryman is more accurate because it can use a more suitable range. The battery supply and thus need for low power just requires compromises. Another point is that the SDM3055 offers a high input impedance up to 2 V (the SDM3065 has this up to 20 V). 4 Wire ohm measurement is another point that handheld meters usually don't support - this may be reason for the better accuracy with resistors, especially small ones. |

Is that bad or good? |
