23 Sensoray Model 417
Chapter 4 Programming
High Speed Mode
This command increases the the channel scan rate to allow higher throughput. Channel processing
time is decreased from 22 milliseconds/channel (default) to 9 milliseconds/channel. Increasing the
scan rate reduces accuracy by approximately sixty percent and will sometimes result in higher
noise levels, due primarily to shortened signal integration time.
A hard or soft board reset will always restore the board to the default scan rate. A board reset is the
only way to resume the default scan rate after invoking the High Speed Mode command.
COMMAND: (224), (8), (0)
RESPONSE: NONE
