I Calibrati Ng The Sensors (If An Opti Onal Ph Link Or Dual Link Module Is Installed) - Zodiac GenSalt OT Series Instructions For Installation And Use Manual

5.3 I Calibrati ng the sensors
5.3.1 Calibrati ng the pH sensor (blue)
The pH sensor may be calibrated in 1 point calibrati on or 2 points (pH 4 and pH 7); 2 point calibrati on is recommended
for more accurate measurement.
Current setpoints are displayed on the Home screen whenever the device is ON.
Current Sensor Measure
• Turn on the device.
• Turn off the pool pump and close valves as necessary to isolate the cell and sensors.
