3.7 Supply of Cleaning water
Check that the flow rate of the cleaning water is correct with Zero water flowing.
(1) Open solenoid valve SV2 via converter “solenoid valve/WIPER OPERATION” menu.
(Note 1) For sampling system codes:-NN and-A1, there is no solenoid valve SV2.
(2) Slowly open valve V4 to allow it to flow so that water does not splash.
(3) Close solenoid valve SV2.
(4) Close detector.
(Note 2) For sampling system cords:-NN and A1, close valve V4 and open each time wash is performed.
3.8 Running-in operation
The operation is conducted for at least one hour while zero water is flowing.
3.9 Setup of operating parameters
TB830D starts operating according to the factory-set operation parameters (default settings).
Before starting measurement, check that the initial data conforms to the operating conditions. If needed,
set up again to perform the desired operation. See “4. SETTING PARAMETERS” and “5. FLXA402T
sensor menu” for the setup. If the operating parameters were setup again, it is recommended to note the
changed data.
(1) Converter’s Display Out setup
* Refer to Section 4 of FLXA402T converter Operator’s Manual (IM 12A01G01-03JA).
(2) Refer to the detector parameter setup “4. SETTING PARAMETERS”.
(3) Setup for Auto cleaning and Auto calibration
The sequence operation is set in the converter setting. See “4.5 Automatic cleaning/
Automatic zero calibration setting”.
3.10 Calibration
Allow TB830D to run for approximately one hour before starting calibration. For calibration, refer
to “7. CALIBRATION”.
