We have a dmm (2701 model) and we want realize a fast scan of 9 channels (all 4-wires resistance measurements). We have a 7706 module but we want to know if a faster module is available? In the current case, with the 7706 module, for one 4-wires resistance channel the duration is around 80ms (1NPLC, autozero on, lsync off, range 1kOhm). We want keep the accuracy we have with this configuration and just improve the scan speed.
Thanks in advance

The relays opening, closing and debouncing are what accounts for the time per sample and will not be any faster in any of the reed relay cards.
