Note: If your unit lacks calibration fluids, you must purchase them separately.
If pH rises above 8.00, the High relay activates. If pH drops below 6.00, the Low relay activates.

If readings are jumping, ensure the power cables for the probes aren't running parallel to high-voltage lines (like aquarium heaters or lights) to avoid electromagnetic interference.
Align the female BNC plug of the pH probe with the left port underneath the controller chassis. Push firmly and twist clockwise to lock the structural barrel. Repeat this step for the ORP sensor on the right port. Remove the protective liquid storage caps from the tips of the glass bulbs before operation. 3. Actuator Power Configuration
