+               Raw (unscaled no bias removal etc.) current measurement from
+               channel Y. In special cases where the channel does not
+               correspond to externally available input one of the named
+               versions may be used. The number must always be specified and
+               unique to allow association with event codes. Units after
+               application of scale and offset are milliamps.
