7. This will add or subtract the value of the offset to the measured NTU value. As an example if the Turb
PLUS 2000 measures the process at 0.36 NTU but the laboratory instrument read the sample at 0.12
NTU, adding an offset of –0.24 would result in the Turb PLUS 2000 displaying 0.12 NTU.
8. Select the desired offset level using the
and
buttons. Once the desired level has been set, press
the
button to accept it.
9. This completes the offset configuration
10. The instrument will return to the
AUTO
mode with the offset mathematically added to the reading.
Operation
NOTICE
Prior to use for the first time, the supplied desiccant pouch will need to be installed.
Installing or Replacing the Desiccant Pouch
The Turb PLUS 2000 continuously checks the condition of the desiccant. When the desiccant
gets in such a condition that it may cause problems, the instrument will display
DESC
on the
lower portion of the display to indicate the presence of humidity.
Proper use of the supplied desiccant is essential in maintaining the performance of the
instrument. The desiccant has been designed to have a long life; however, replacement of the
desiccant pouch will be required from time to time.
It is essential that the enclosure seal on the instrument base be maintained to ensure adequate
desiccant life. Inspect the seal each time the desiccant pouch is replaced. Replace or reseat the
seal if it is found to be defective.
The desiccant should be replaced when the instrument displays
DESC
. A new, sealed desiccant
pouch and indicator card are available from Xylem Analytics Germany.
1. To initially install or remove the old desiccant, simply unscrew the four corner thumbscrews and remove
the electronics half of the instrument.
2. If replacing an old desiccant pouch, remove the used desiccant pouch from the instrument.
3. Open the bag protecting the new desiccant pouch.
4. Insert the new desiccant pouch in the instrument base assembly.
