6.2 Operation Modes and Functions
Operation of the turbidimeter is divided principally into three operation modes (modes are
classified into four types).
(1) Measurement mode (<MEAS.> mode) (subsections 6.2.1)
(2) Maintenance mode (<MAINT.> mode) (subsections 6.2.2)
(3) Setting modes
• Data setting/operation setting mode (<PROGRAM1> mode) (subsections 6.2.3)
• Automatic cleaning and zero-calibration setting/failure detection function selection mode
(<PROGRAM2> mode) (subsections 6.2.4)
Display or setting items for data and command items, such as for calibration, are determined by
functions in each mode. Accordingly, various operations require designation of a mode and a
function code.
Table 6.2 outlines the modes and the function codes in each mode. For details on function codes,
see subsections 6.2.1 to 6.2.4.

(FUNCTION)
Description
MEAS. to
This is the mode for steady operation in which turbidity is measured. If
execution of automatic cleaning and zero calibration is selected, a sequence
operation is carried out. (Suffix code: A2 or A3)
MAINT. to
This is the mode for performing maintenance in which calibration can be
done (implemented items are selected using the [FUNC] key). The data set
key and valve operation keys can be operated.
PROGRAM.1
to
Data can be set such as output range setting. (The setting items are selected
using the [FUNC] key). The data set key and valve operation keys can be
operated.
to
Operating functions such as range switching (automatic, remote/local) and
execution/stopping of automatic cleaning can be selected (setting items are
selected using the [FUNC] key). The data set key and valve setting keys can
be operated.
PROGRAM.2
to
The cleaning and calibration sequence time can be set (setting items are
selected using the [FUNC] key). The data set key and valve operation keys
can be operated.
to
Execution/stopping of failure detection can be selected (setting items are
selected using the [FUNC] key). The data set key and valve operation keys
can be operated.
