Hi at all, We got a yokogawa MV2000 form the early 2000s years here for several purpopes, mostly logging temperatures for a long time up to 96h. Actually we use it for tests by logging input voltage, output voltage, output current and several temperatures(It got more than 16 channels). "Now" we need a second one, because this will be in a testsetup for years. It´s a good chance to get one with "better" parameters, for example the maximum voltage input of the modules from the MV2000 are 50V. I´ve asked yokogawa for a actual replacement, it will be the sirius series, but they cost up to appx 9000€ and are having the same limitations concerning maximum input voltage. Could it get better and cheaper ? The yokogawas get the advantage of an inbuilt display - But this isn´t a must have. We need at least 16 channels, maximium record time of 96h, very nice to have would be an input voltage up to 250VAC. Or more precisely: Input voltage 3 phase 400 hz, 200Vac. Input current up to 16A (or via shunt) Output voltage up to 30Vdc Output current up to 200Adc ( definitely via shunt I guess...) Several temperature meausure points on the DUT. What about the rigol M300 system ? |

I would definitely contact Rigol support with actual question. Keyword here is maximum permissible voltage. Current you have to measure trough shunt. Scan cards are break before make, so they disconnect current path.. Use shunts and measure voltages. Temperature measurement shouldn't be a problem.. A custom code to control and scale would need to be made.. M300 has a display and can chart but is much smaller and simpler than Yokogawa.. |

Hi, What maximum voltage concerns, this wouldn´t be a problem because of the 6.5 digits DVM module the M300 system can be equipped with. https://www.batronix.com/shop/multimeter/Rigol-M301.html But you´re right, contacting them (rigol or batronix) will be the best solution in this case. |

Contact support and explain the setup. If they say it is OK it is OK... |
