Eric mentioned that sometimes the polarity of a line can change and that
this might be the reason that inject hold was activated.
We've looked on the Gold system computer settings for the control of the
pump--both in the configuration of the Gold system and in our methods and
sample tables to see if we activated an inject hold somehow.
But in the meantime, we have got the 506 operating.
