4. Press or

to input the pH value.

5. Press when the pH reading on the top line becomes stable.

5.1.2 pH Calibration Notes

1. The

Chemflo

pH probe has an allowable Asymmetry range of –1.00 to +1.00 pH. If calibration

fails due to the Asymmetry being outside these limits, please consult the Troubleshooting

guide (section 7.4) for possible remedies.

2. All calibration information is retained in memory when the

Chemflo

is switched off, even when

the power supply is removed.

5.1.3 pH Calibration Messages

1. If a calibration has been successfully performed, the

Chemflo

will display the following

message and the asymmetry of the probe. For example…

Calibrate OK

Asym=0.10pH
