Setting the switch-point adjustment

If only one calibration (empty or full) was carried out, and if buildup forms on the rod
probe while the probe is in operation, the device may no longer respond to changes in
level. A switch-point adjustment compensates for this condition and ensures that you
obtain a constant switch-point again.
For media that do not have a tendency to build up, we recommend a setting of 2 pF,
as the probe is most sensitive to changes in level at this setting.
For media with heavy buildup, is recommended to use the probes with active buildup
compensation with the setting of 10 pF.
Switch-point adjustment:
 49 10 pF
