962,"def set_series_resistance(self, channel, value, resistor_index=None):
'''
Set the current series resistance value for the specified channel.
Parameters
----------
channel : int
Analog channel index.
value : float
Series resistance value.
resistor_index : int, optional
Series resistor channel index.
If :data:`resistor_index` is not specified, the resistor-index from
the current context _(i.e., the result of
:attr:`series_resistor_index`)_ is used.
Otherwise, the series-resistor is temporarily set to the value of
:data:`resistor_index` to set the resistance before restoring back
to the original value.
See definition of :meth:`safe_series_resistor_index_read`
decorator.
Returns
-------
int
Return code from embedded call.
