Optional Service Test
If desired, the circuit board can also be tested while in the Service mode.
1. Unplug control.
2. Disconnect probe and connect Soft-Minder Meter/Aqua-Sensor® Simulator (P/N 01017705) and set to the "balanced"
position.
3. Plug in the control.
4. Press the "Information" key once and then repeatedly press the "down" key until "z-ratio" is displayed. Wait 30 seconds for
the reading to stablize.
5. With the simulator device set to "Balaced", the "Z-ratio" should read between 900 and 1130.
6. Set the simulator device to "Unbalaced" and wait 30 seconds for the reading to stabilize. The "Z-ratio" should read between
1130 and 1250.
Sensor Probe Resin Test
The Probe Resin Test uses fully regenerated, but previously used, Cullex® resin to simulate a balanced environment. Run this
test only on a circuit board that has passed the Circuit Board Test with simulator device.
Preparation
You will need a container that can hold enough regenerated Cullex resin to completely immerse the probe's electrodes without
making contact with the container's sidewall. A section of PVC pipe, either 2" or 3", makes a suitable chamber for testing either
residential or commercial probes.
1. Cut a piece of pipe about 18 inches long and close the bottom end with a cap or a flat piece of PVC (which can also serve
as a base)
2. Close the other end with a cap that has been drilled and tapped for a 1" PVC pipe plug, or use a reducing adapter and plug.
3. Fill the chamber with used, regenerated Cullex resin and soft water; the water level should be at least one inch above the
resin (when not in use, plug the end to prevent spillage of resin and water)
Probe Test
1. Remove the probe from the resin tank. Make sure pressure is relieved on tank before removing probe.
2. Visual inspection
a. Look for discoloration (brown film or blue spots) on electrode fins.
b. If discolored, try cleaning the probe (Sofner-Gard chemical or white vinegar). The fins can be lightly scrubbed with a soft
toothbrush.
