• At this point, ensure that the pH probe is placed into the pH 7 solution (ref Figure 6.12). Currently
the probe blanking plug should be plumbed into the probe & injection point housing, you will need to
remove it. Ensure that your circulation pump isn't running, or isn't about to run. For above ground
pools (or pools where the water level is higher than the equipment) it may be necessary to close
isolation valves to ensure water doesn't flood from the pool;
• Once the pH probe is bathing in pH 7 solution, press
• The screen will next display pH calibration in progress (refer Figure 6.13). A count will commence.
Typically, the calibration will take less than 15 seconds, but may take up to a minute;
