UNCTION ARAMETERS
vi = contains a session handle to the instrument. This handle is obtained by the function and remains valid until the
session is closed.
channels = the list of channels to which to apply the filter frequency selection. The list of channels can include
channels not currently in the scan list and can be a subset of the channels in the scan list.
numChannels = the length of the channels array. Value must be an integer in the range of 1 to 48.
range = sets the input range of the specified channels. Valid input values: 0.01 (10 mV), 0.067 (±67 mV), 0.1
(100 mV), 1 (1 V), and 10 (10 V).

range = 0.067 for thermocouple channels, 10 V for voltage channels.

ESCRIPTION
This function specifies input range of a voltage channel. If the channel specified by the channels parameter is a
thermocouple channel, an error will be returned. If an invalid range value is used, the value is rounded up to the
next highest valid range. If a value is greater than 10.0 V is entered for the range parameter, an error will be
returned
