What sampling rate do you need? |
| Martin72:
Hi, It's hard to say when it was completely analog before. I had looked at the device today for the first time, looks funny with the paper roll inside, with the millimeter imprint. 8) But the colleague who told me that we need something new, he can tell me tomorrow times, where he wants to have the measurement voltage connected to the recorder. I could not see anything earlier, except temperature inputs .. ::) |

Yepp, that's why tomorrow I'll have the protocols given to me where they had pasted the paper sections. |

Seems to be the better choice compared to multimeters but also more expensive. The ones you mentioned seem to be discontinued. But there is the DAQ970A / DAQ973A now. And from Keithley the DAQ6510. --- End quote --- I think a DMM6500 with a 2001-TCSCAN card should be enough if all you need is a few thermocouple and voltage channels (up to 125 Vrms). IIRC the DAQ6510 just has more cards available (with higher channel count/special features) and you can install two of those at the same time. EDIT: The pricing on the DAQ6510 + 7700 bundle seems to be pretty similar though. So still worth a look if you don't have a DMM6500 already. |
