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).

Remark 1: Under the setting for Hipt & Lopt, press "ENT" to show
(screen flashing)
Press "ENT" button to save the value and then press "UP" button
to escape the setting.
Note 2: When Hipt or Lopt setting is over range, the LCD show
"Err", Please reset the value.

For example, changing SCH
value from "1230" to "1234" is to
press this button fourth.

The rod probe or cable probe (depending upon which one you
purchased ) should be parallel to the tank wall and be positioned
as close as possible to the tank wall. Make sure the medium
does not stick in between the probe and the tank wall.
If the tank is not electrically conductive, a metal strap should be
added outside of tank wall (fig. 1) for either liquid or non-liquid
medium. Or place a metal tube, usually made out of stainless
steel, around the rod (fig. 2) for liquid medium. This metal tube
should come with a vent hole at top of the tube to allow the
medium to go up inside of the tube.
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 metal tube with vent hole at the top. (Fig. 2)
For non-conductive medium of powder or granuules in a new or
empty tank, the cable probe should be fixed to the bottom of tank
with ceramic isolator (EB2100 Series. If the tank is not empty,
please use the EB2300 Series. (fig. 3)
Make sure to fix the rod probe or cable probe to the container
wall with non-conductive supporting material. If an agitator is in
place (see fig. 4). This will prevent the deformation of the rod
probe and tangling of the cable probe around the agitator.
If the medium is conductive, make sure to coat the rod probe or
cable probe with PVDF or PP material.
During the installation, the process connection should be
grounded. An installation without proper grounding will not
guarantee normal operation of the device later on.
When all electrical connections inside of a Capacitance Level
Transducer housing are finished, the housing cover and the
conduit opening should be sealed and tightened to prevent
moisture from soaking in.

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.
