Test results

Factory run times are as follows. The test time for an equivalent setup using the Model 7703 has also
been provided so that you can see what is achievable with the reed relays.
Differential Multiplexer Module Setup
7710: 20-channels for 1000 scans at 20,000
readings
7703: 20-channels for 1000 scans at 20,000
readings
7700: 20-channels for 1000 scans at 20,000
readings
The 7710 multiplexer module provides readings to the DAQ6510 faster and has the speed
advantage.
