4. The display shows Ct2 for entering the second point calibration.
Clean the sensor before immersing it into well-prepared standard
solution. Constantly stir the solution. Press to confirm it.
Enter turbidity range selection.
1. Enter CT1 Calbration mode. After cleaning up the sensor,
inmmerse the sensor into 0.00 NTU standard solutioin. Press
to confirm it. The display shows “0.00NTU”. Continually
press to send the calibration signal to sensor.
5. Enter turbidity range selection, press or to select
suitable range. Press and the value starts to twinkle. Press
or to adjust value until it is the same with the standard
solution’s value. Press to display the analog signal of the
sensor.
Two or up to five points calibration, and in which “Ct 1” must be 0 NTU calibration.
Offset calibration.
Turbidity standard solution 2 to 5 point calibration
2. At the time, the sensor responses 2 mA analog signal to indicate
that the sensor is in the process of inner calibration.
3. After inner calibration of the sensor, it responses 4 mA analog
signal to transmitter. Press to calibrate the sensor with the
0.00 NTU standard solution.

9. The display shows Ct5 for entering the fifth point calibration. The
procedure is the same as step 4~6.
Note: To finish the calibration procedure as a four point
calibration, when the display shows Ct5 please press and
skip to step 10.
10. When the calibration is successful, the display screen shows the
word “CAL PASS”; when the calibration is unsuccessful, the
display screen shows the word “CAL Err”. (Please refer to chapter
10 for error message, causes and treatment seeking.)

Note: Before the implementation of offset calibration,
it is necessary to make a 2 to 5 points standard
solution calibration in advance.
4. When the calibration is successful, the display screen shows the
word “CAL PASS”; when the calibration is unsuccessful, the
display screen shows the word “CAL Err”. (Please refer to
1. After entering into display CA, put the sensor which has been
cleaned into turbidity standard solution, and constantly stir the
solution. Press to confirm and enter into turbidity range
selection.
2. Enter turbidity range selection and press or to

Wrong wiring will lead to breakdown or electrical shock of the instrument, please read this
operation manual clearly before installation.
zMake sure to remove AC power from the controller before wiring input, output connections,
and remove it before opening the controller housing.
zThe installation site of the controller should be good in ventilation and avoid direct sunshine.
zThe material of signal cable should be special coaxial cable. Strongly recommend using our
coaxial cable. Do not use normal wires instead.
zAvoid electrical surge when using power. Especially when using three-phase power, use
ground wire correctly.
3.Assemblyandinstallation
3.1 Controller installation: This controller can be installed through panel mounting, wall
mounting and pipe mounting.
Installation of panel mounting: First,prepare a square hole of 138 x 138mm on the panel box,
and then insert the controller directly into the panel box. Insert the accessorial mounting
bracket from the rear, and make it be fixed in to pickup groove.
