Operation

Routine Measurement: AUTO Mode

After the instrument has warmed up and the instrument is operating in AUTO mode, readings will
be updated (posted) once per second. These updates occur to the screen, Modbus, 4-20mA and
can be logged internally to the instrument. These updates also affect the operation of the alarms.
Please note that these updates are all affected by the setting of the Signal Averaging (see section
6.2.7) and possibly Offset (see section 6.2.5).
If power is lost at any time, once power is restored, the instrument will restart and the instrument
will continue in AUTO operation with the same settings. There may be some slight instability if the
instrument cooled off. If the onboard data logging was used it will record 0.00NTU during the
period that instrument is not running.
The Turb PLUS 2000 can read up to 110% of the range. Readings above
100% of the range may not be accurate. After 110% of that range the display
will flash indicating an over-range condition. The 10 NTU range can display
up to 11 NTU, the 100 NTU range can display up to 110 NTU, and the 1000
NTU range can display up to 1100 NTU.

Data Retrieval

Data is available in several forms. It can be viewed on the screen, logged in the instrument, read
via Modbus or output the 4-20 mA.

7.4.1 USB Connection

The USB connection can be used to upload new software or download logged data and
calibration reports via a USB flash drive.
Software uploads can be made by loading the software onto a USB flash drive and inserting it into
the USB connector. The update will not affect configurations or stored data, however it always
advisable to check the configuration as menus may change. The instructions are in section 6.2.18
of this manual.

7.4.2 File Downloads

All files download in a CSV (comma separated value) file format. These are easily imported
directly into most spreadsheet and database programs. The main data includes the Date, Time,
Reading, Units, Alarm 1 and Alarm 2. The instrument ID is part of the file name. For more
information on downloading data logged files, see 4.2.16
