CALIBRATION PROCEDURESSETTING FLOWCHART FOR EACH FUNCTION
Standard procedures:
1.SCH : Set the max display value corresponding to 20mA at SCH.
2.SCL : Set the min display value corresponding to 4mA at SCL.
3.HIPT : Input and save the corresponding value at HIPT, while the
medium is in high level.
4.LOPT: Input and save the corresponding value at LOPT, while the
medium in is in low level.
Completed Calibration
Example 1:
The lowest value sets at 0 and the output sets at 4mA.
The highest value sets at 100.0 and the output sets at 20mA
Calibration is done in empty and full tank.
Example 2:
The lowest value sets at 100.0 and the output sets at 4mA.
The highest value sets at 200.0 and the output sets at 20mA
It is calibrated at 10% of tank high and 90% of tank high. The 0%
of the total height of the tank is corresponded to 4mA, while the
100% of the total height of the tank is corresponded to 20mA.
Procedures of calibration for example 2
1. Input:
Dot=1, SCL=100.0,
SCH=200.0
(It can be adjusted anytime; Nothing is related with the status
of tank.)
2. To fill the medium till reaching to
the 10% height of the tank, go to
the LOPT setting and input the
value of 10.0 and then press
"ENT" "SAVE'' (Remark 2).
3. To fill the medium till reaching
to the 90% height of the tank,
go to HIPT setting and input
the value of 90.0 and then
press "ENT" "SAVE''
(Remark 3).
3. When the tank is full, go to
HIPT setting and input 100.0,
then press "ENT" "SAVE"
(remark 1).
Procedures of calibration for example 1
1.Input：
Dot=1, SCL=0.0
SCH=100.0,
(It can be adjusted anytime; Nothing is related with the status
of tank.)
2. When the tank is empty, go to
the LOPT setting and input 0.0,
then press "ENT" "SAVE"
(remark 1).

Press "ENT" button to save the value and then press "UP" button
to escape the setting.
Remark 2: When Hipt or Lopt setting is over range, the LCD show
"Err", Please reset the value.

WIRING AND CAUTION
1. Please install a concentric circles
2. The rod or wire probe should be parallel to the tank wall. To
prevent material from sticking between the probe and tank
wall , the probe shouldn't be too close to the tank wall.
3. If the container is irregular-shaped, such as a cylindrical ,
and the medium is liquid with low viscosity, the rod should
be placed inside a concentric circles metal with
vent hole at the top.(Fig. 1)
4. Coating Probe type is necessary for conductive media (eg.
Water...) , as the bare electrode can't operation normally in
conductive media.
5. During the installation, the process connection should be
grounded. An installation without proper grounding will not
guarantee normal operation of the device later on.
6. For non-conductive medium of powder or granules in big
tank , the wire probe should be fixed to the bottom of tank
7. When all electrical connections inside of Admittance Level
Transmitter housing are finished, the housing cover and the
conduit opening should be sealed and tightened to prevent
moisture from soaking in.
8. If an agitator is in place (see fig. 3), a pipe shield outside the
probe is recommended.

hole at the top outside the probe (Fig. 1)

1.Read installation notice before calibration.
2.It is recommended to have the media touched probe
bottom when users calibrate lowest value for empty tank.
3.Doring calibration, pribe should be put into the tank.
Don't calibrate the product outside the tank.
4.Please keep at least 50% distance between HIPT and LOPT
to ensure accuracy. It is recommended to calibrate with
empty and highest level in the tank.

2 Connect isolation cable with GND of power.
2 Connect tank with heater or cover of electric device to decrease
EMI.
After installation of the Compact Capacitance LevelTransmitter on
the top of tank, please make sure the cover of the transmitter is
contacted with tank perfectly. Please avoid the grounding of panel
meter to touch the tank wall.
While the panel meter is not supplied with a power supply, please
prepare a 24V power supply for use. The wiring for panel meter is
showing in diagram 1.
The max cable length is depends on the max resistance.
Maximum resistance is not to exceed (Vs-15)H50W to
ensure the accuracy of measurement.
Make sure to separate the signal cable with other big power
cables (such as pump, conveyer and solenoid valve)while wiring.
Before turning on power, make sure all wirings are correct.
