Specs: How fast does the 2700 measure and scan channels?

This really depends on the function, range, measurement characteristics, alarm/limit status, scaling, timestamp, etc. selected, as well as the input module used. Generally, the 2700 offers single-channel speeds of up to 2000 readings/second. Scanning is typically in the 65-185 channels/second range. These speeds are for fully traceable, settled, formatted measurements (not raw A/D counts that need extensive post-processing), so be sure to consider these issues when making comparisons.
