IS-HF-AccUViewLEDEx-100125 Rev 0 14Routine MaintenanceCleaning the Flow Through CuvetteMeasurement cuvettes used for the flow through should be clean andfree of marks or scratches. The interior and exterior of the cuvette canbe cleaned with a detergent solution and then rinsed several times withdistilled or de-ionized water.To replace the cuvette:1. Shut off the flow using the provided shutoff clamp.2. Unscrew the old cuvette and replace with a fresh, clean cuvette.3. Recalibration is required for accurate operation.Replacing the Source LEDThe life of the UV source lamp in the AccUView LED Ex is dependenton the setting of the Duty Cycle and operating conditions. See sectionon Duty Cycle for more information on the LED life.When the UV source LED requires replacement, it is required to openthe enclosure. Contact the HF scientific Customer Service departmentbefore servicing or to purchase a service module.Input RegistersThese 16-bit values are readable by the master.
