What is the max switch read rate of the Model DAQ6510 with the 7710 FET switch card?

The specs state that >900 channels per second.
But a quick test just from the front panel was able to attain 1041 switch/reads per second on DCV.
The conditions were as follows...
NPLC = 0.0005
Fixed 10V range.
Filter disabled.
Trigger delay= 0.0
Autozero disabled.
Turning off the display remotely may increase speed futher.
