Adjusting the Length of the Electrodes
1. Firmly grasp the white adjustment nut at the end of the electrode body with one
hand. With the other hand hold the shaft of the electrode body. Rotate the nut
clockwise to shorten the electrodes. Rotate it counter-clockwise to lengthen the
electrodes.
NOTE : The ring should extend a little beyond the steel surface. This allows the
step in the ring to engage the outer edge of the insert (or the tri supports of a
hanging insert).

of the electrodes.
Fig. 7—The electrode length is properly
adjusted.
2. Align the electrodes with the well inserts and position the STX2-PLUS over the well
so that it rests securely in an upright position. (Images shown with a Corning 3470
24-well insert and plate. For greater stability, rest the cable on the tabletop. For
other plates and inserts, center the electrodes and the weight holds the electrode
in place when making measurement readings.
Fig. 8—The outer electrode reaches close to
the bottom of the well plate, and the inner
electrode does not touch the membrane.
Fig. 9—The STX2-PLUS sits securely over a
well insert.
