1. During pH EasyCal, the
detected sensor input is
more than 2PH away from
the selected pH value or
the range of possible
buffer values.
2. During pH Standard/Slope
calibration, the detected
sensor input is more than
2PH away from the
entered pH value.
3. During ORP One Point
calibration, the detected
sensor input is more than
120mV away from the
entered ORP value.
1. Check the sensor and restart
the calibration procedure.
2. Press “Enter” to accept the
value.
Please Maintain

1. During pH EasyCal, the
detected sensor input is
more than 4PH away from
the selected pH value or
the range of possible
buffer value.
2. During pH Standard/Slope
calibration, the detected
sensor input is more than
4PH away from the
entered pH value.
3. During ORP One Point
calibration, the detected
sensor input is more than
240mV away from the
entered ORP value.
1. Press “Enter” to interrupt the
calibration. Replace the
sensor and restart the
