(FUNCTION)
Description
MEAS. 1
to
8
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. (Suf fi x code: A2 or A3)
MAINT. 1
to
F
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
1
to
F
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.
1.
to
F.
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
1
to
F
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.
1.
to
9.
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.

Note 1: The values in the column for the initial value are those shown when the memory storing the data is initialized.
These are partially different from the values set upon shipment from the factory.
(*1), (*2) These are indicated by reversing the sign (+ or -) for the voltage values obtained by placing the AG terminal of the detector to
the negative side (-).
(*3) "FTU" unit, a turbidity unit when formazin standard is used, is also available. Since the instrument uses kaolin standard,
reference sensitivity calibration using formazin standard is required for the FTU display.
