Commissioning OUSTF10 You can dilute the suspension to produce a series of optical standard solutions. You can check the calibration of the measuring system with the standard solutions. Stock suspension [ml] Ultrapure water [ml] 97.5 It is not recommended to dilute the stock suspension below 4 FTU.
OUSTF10 Maintenance There are two ways to calibrate/adjust with CM44P: • Calibration Zero point calibration or two-point calibration • Application adjustment You create a maximum of five calibration datasets which are each adapted to your particular application. Calibrating the measuring system ‣...
Maintenance OUSTF10 Replacing the hazardous area lamp The disassembly and assembly process for the hazardous area lamp is the same as for the non-hazardous area version. Make sure you use the right spare parts kit. Replacing the collimated incandescent lamp Preparation Switch off the lamp using the software function on the transmitter.

OUSTF10 Maintenance Loosen the two securing screws on the optical project unit (a) and then carefully unscrew the optical projection unit (b). Dispose of the lamp unit, along with the cable connector, in accordance with local regulations. Insert the new lamp unit into the optical projection unit and retighten the securing screws.
Maintenance OUSTF10 Screw the lamp module clockwise onto the flow assembly. A zero point adjustment is required after replacing the lamp. Replacing the sensor window and seal Operating Instructions for Flowcell OUA260, BA01600C Operating Instructions for CUA261, BA01652C If you have mounted the sensor in a VARIVENT flow assembly using the CUA261 adapter, refer to the Operating Instructions of the adapter for information on removal and on replacing the optical windows.
