INPUT:POLARITY
The input polarity command selects the input polarity for one or more channels. When a channel
is programmed for normal polarity, an interrupt will be generated when the input voltage is
greater than the programmed input offset for the channel. The invert polarity will cause an
interrupt when the input voltage is less than the programmed input offset for the channel.
INPut:POLarity <polarity>,<channel_list> Where <polarity> is either NORMal or
INVerted
Where <channel_list> is the standard
channel list format supporting channels 1
through 16.
EXAMPLES
INPut:POLarity NORM,(@3:5)
Sets the input polarity for Channels 3
through 5 to NORMal. This will generate an
interrupt when the input signal on Channels
3, 4, or 5 is greater than the input offset.
INPut:POLarity? 5
Returns the input polarity for Channel 5 as
NORM NORMal
INP:POL INV,(@6)
Sets input polarity for Channel 6 to invert.
