Emptying of Measuring Cell
After startup, conduct emptying operation on the measuring
cell.
Maintenance Function
Before entering the maintenance function, the
corresponding permission is required. During equipment
maintenance, all operations are slightly different from those in
non-maintenance mode in data identification, data result
transmission and storage.
Only when entering the maintenance mode, can maintenance
be conducted. Maintenance includes the operations of
routine maintenance, hardware maintenance, equipment
self-detection and system management. When entering the
maintenance interface and checking the maintenance mode,
the interface will prompt "Entered the maintenance mode".
Maintenance operations such as the instrument maintenance,
hardware maintenance, etc. can only be carried out after
entering the maintenance mode.
It is recommended to enter the maintenance mode only in the
idle state. If the maintenance mode is checked in the non-idle
state, the current operation needs to be stopped for emptying
and cleaning, and the maintenance operation cannot be
carried out until the emptying and cleaning are finished.

Routine Maintenance
Instrument maintenance includes the operations of
pre-loading tubes, emptying of the measuring cell and
reaction cell, sample pre-mixing, routine cleaning, deep
cleaning, and back flushing, etc.

System Running
Tube Pre-loading: For each instrument operation, the tube
pre-loading (priming) is a process that must be implemented.
Tube pre-loading includes the water sample pre-loading,
standard liquid pre-loading, reagent 1 pre-loading, reagent 2
pre-loading, reagent 3 pre-loading, and deionized water
pre-loading, etc.
When selecting the corresponding item, set the pre-loaded
volume, and then click "Start" to start tube pre-loading.
Emptying of Reaction Cell and Measuring Cell: It is used
to emptying the reaction cell and measuring cell. After
entering the sub-item, click "Start" to start the sub-process.
Sample Premixing: It is used to mix samples. Click "Start" to
start the sub-process.
Routine Cleaning: It is used for the routine cleaning of the
measuring cell and reaction cell. DI water is injected into the
measuring cell and reaction cell several times, and conduct
mixing to clean the possible common residues in the
measuring cell and reaction cell. After entering this interface,
click "Start" to start routine cleaning.
Deep Cleaning: For deep cleaning, see Manual Operation
(measurement) part: Deep Cleaning.
DANGER: Exposure to an inhalation of
chemicals are hazardous. Only trained and
qualified personnel can perform the work
described in this section of the user manual.
Deep cleaning solution (either concentrated sulfuric acid
≥
90% or 10% HCL) is required for deep cleaning. It is
recommended to purchase these chemicals from your local
chemical suppliers.
Back Flushing: It is used to clean calibration fluid, and tube
lines R1, R2 and R3. When using this function, ensure that the
tube line is not connected to the solution bottle, otherwise it
may cause contamination of solution. During back flushing,
DI water back flushing is adopted. After entering back flushing
interface, click "Start" to start back flushing process.
Hardware Setting
Hardware setting is used to set the relevant hardware of the
instrument, including light path calibration, liquid path sensor
calibration, thermistor calibration, analog output 1 calibration
and analog output 2 calibration.
