Performing additional ISE electrode washes

ISE Detergent Solution is automatically run through the ISE module as part of the shutdown wash procedure (WASH2). Manually perform additional ISE washes (described in the following procedure) once per shift under either of the following circumstances:

·   Dialysis samples are run routinely.

·   The system is run more than 8 hours per day.

NOTE
