Switchable between automatic zero calibration command
and transmission hold
EXT2
Switchable between cleaning command and transmission
hold
EXT3, EXT4 Selection command from four ranges using 2-bit contacts
Communication
function
Type RS-485
Signal form
Two wire type, the power source of the communication is isolated from the
power of measurement circuit (the power source of transmission and
communication are not isolated).
Calibration
Calibration
method
Zero calibration By filtered clean water
Automatic zero
calibration Zero calibration is performed automatically by switching to
the filtered clean water (option)
Span calibration Turbidity adjustment method by coefficient input
Compatible standard substances Kaolin, Formazin (NTU), PSL
Automatic zero
calibration (option)
Zero calibration
method
The electric valve of a sample line is closed, the electromagnetic valve of a
zero line is opened, measured value is automatically judged to be zero within a
time, and zero calibration is carried out.
Setting
Calibration cycle 1 to 999 (h)
Stability time
1 to 60 (s)
Stability level 0.01 degrees/NTU to 0.05 degrees/NTU
Hold time 60 s to 600 s
Cleaning function
(option)
Cleaning method
Electric wiper type (executes cleaning operation by
communicating with the converter)
