• If the resistance values are not out of expected range, but electrode response continues to be slow or
erratic, these effects may also be seen as a result of reference clogging or contamination. You should
reference the additional electrode care notes below.
• If the resistance value between checks increases substantially higher, the fill solution may be
depleted. Refer to the additional electrode care notes below for the proper fill solution levels of a
refillable electrode.
• If the resistance values show a “super high” resistance, cleaning and care may improve performance,
but will not be able to return the probe to like new condition. Consider purchasing a new electrode.
