Page 4: Description
Description The Swimming Pool Controller is an automatic system to measure and control levels of pH and free chlorine in a swimming pool or a spa. The chlorine level is measured based on the ORP of REDOX principle. An increase of the ORP value correlates with an increase of the level of free chlorine. -

Page 23: Ph Calibration
The BL121 can calibrate the pH probe using an Automatic, two points from three available values (4.01, 7.01, 10.01 pH) calibration. If the buffer calibration was made a process calibration can be performed in one adjustable point. Calibration The probe should be calibrated: •... - Page 24 The Error messages in buffer calibration are the followings: Calibration Wrong Buffer: This message appears when the difference between the pH reading and the value of the selected buffer is too great. If this error message is displayed, check if you have selected the proper calibration buffer and have poured the desired buffer.
-
Page 25: Orp Calibration
The pH calibration is affected by pH buffers contamination that could appear if the probe was used in ORP standard solution. It is recommanded to perform the pH calibration first. Calibration Pour calibration solutions into clean beakers. If possible, use plastic to minimize any EMC interferences. For accurate calibration and to minimize cross-contamination, use two beakers;... -
