Operation
Preparation for operation
When you start using the converter for the first time after factory shipment or resetting it to
factory settings, be sure to complete the following preparation procedures.

Check of converter and detector installation condition (refer to “ Installation method ”
(page 12)).

Check if the wirings are correct (refer to “ Wire connection ” (page 18)).

Check if the terminal block screws are firmly tightened.

Check if the piping for mistake (refer to “ Piping ” (page 14)).

Initial setup (selection of turbidity standard substance, transmission signal setting,
operation condition settings for relay contacts, etc.)

Calibration (zero and span) (refer to “ Calibration ” (page 59))
At the time of shipping from the factory, span calibration has already been performed
using Polystyrene Latex. As the calibration information stored on the sensor is called up
when the power is turned ON, calibration using Polystyrene Latex is not necessary.
However, span calibration is necessary if Formazin or Kaolin is used as a span solution.

Initial setup
The converter is shipped with initial settings from the factory.
If necessary, change the initial settings according to “ Entering the setup menu ” (page 38).
Note

Before starting operation, be sure to set the items grayed out in the following table.

When Kaolin is selected, set the item of “Selection of turbidity unit or SS unit (mg/L) for Kaolin”.

When an automatic zero calibration function (option) is provided, set the item of “ Automatic zero
calibration setting ” (page 41).

When a cleaner (option) is provided, set the item of “ Cleaning operation setting ” (page 45).
For the initial values, refer to the table below.
