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
