Page 20: Commissioning
Commissioning OUSAF44 Commissioning Function check Prior to initial commissioning, ensure that: • The sensor is correctly installed • The electrical connection is correct Calibrating/adjusting the sensor Measuring points consisting of a photometer sensor, flow assembly (if provided) and a transmitter are adjusted at the factory. Normally adjustment is not required when commissioning for the first time. - Page 21 OUSAF44 Commissioning While the D-tryptophan is dissolving, add deionized water until the beaker contains an approximate volume of 450 ml. Continue stirring at 30 °C (86 °F) until the tryptophan is completely dissolved. Dilute the solution to 1000 ml in a volumetric flask.
- Page 22 Commissioning OUSAF44 It is very important that you use the actual values of the optical Easycal filter. These values are given in the calibration certificate supplied. ‣ Enter the absorbance values (CM44P): Menu/Setup/Inputs/Photometer/Extended setup/Measurement channel/Calib. settings/EasyCal = Yes, NIST filter high and NIST filter low.
