Once the bag is opened, install the desiccant pouch immediately to
prevent premature degradation of the desiccant.
5.2 Starting the System
The following steps describe how to measure the turbidity of a sample
using this instrument:
1. Apply power to the instrument and allow the unit to warm up (typically
45 minutes – 1 hour on initial commissioning).
2. Check the cuvette to make sure it is tight before starting the flow. The
cuvette should be handled at the top ½” to prevent fingerprints from
interfering with readings.
3. After the initial warm-up period and once a continuous process stream
is flowing through the instrument, the instrument will display the
measured turbidity level of the sample by displaying it on the LCD
screen. In addition, the equivalent signal is provided on the analog (4-
20 mA) output, or the digital output, depending on the options selected.
4. Initial settings like Date and Time (section 4.2.17) must be set now.
