4.1.5 Channel State Indicator Colors.
channel state. A gray indicator corresponds to a disabled or absent channel. A
green indicator corresponds to a channel with valid measurements.
indicator corresponds to a channel with invalid measurements that have been
persistent for more than a programmed acceptable level, i.e. they are
continuously outside the valid minimum and maximum values. This generally
indicates a disconnected channel and the channel value field will eventually be
cleared to avoid confusion. An orange indicator corresponds to invalid values
that have not been held.

on a busy system and becomes starved for computational resources.

Record buttons correspond to all channels simultaneously. The Calibrate button
calibrates the measurements for the current channel selected in the board
configuration.

button is automatically reset to its initial state to indicate that another recording
can be made. The SCP software is set to record 100 samples each time the
