<1. OVERVIEW>
1. OVERVIEW
The applications of turbidimeters, which have been used for operation or control of ltration
plants, are expanding into turbidity detection in chemical processes and in measurement of
suspended solid particulates in various types of industrial wastewater.
Model TB400G Surface Scattering Light Turbidity Meter is a process turbidimeter employing the
principle of measuring surface-scattered light. This instrument has the following features.
• High performance, high reliability
• Self-diagnostic functions (such as detection of a disconnected lamp, automatic converter
checking functions, and upper and lower limit alarms).
• Choice of functionality (such as automatic cleaning, range-free function, automatic zero
calibration, etc).
• Easy maintenance through small, light-weight, and accessible design.
• No window surfaces to become contaminated.
• Bubble rejection signal processing.

<1. OVERVIEW>
1.1 SystemConguration
The TB400G Surface Scattering Light Turbidity Meter comprises a detector, converter and
sampling system (which supplies process sample water, zero-calibration water (“zero water”),
and cleaning water). This instrument is classied into three types depending on the specications
for the sampling system. However, if specied in advance, the detector and converter may be
delivered separately.
Here, four types of the instrument, including the delivery of detector and converter separately,
will be described. Details on the detector and converter are described in Section 1.2, “Operating
Principle”.
1.1.1 TB400G-¨-¨-NN, -KC (without sampling system)
The detector and converter are available separately and can be assembled into any sampling
system.
The owrate condition for sample is 1.5 to 2 L/min. If the owrate exceeds this range, satisfy the
owrate condition by providing a head tank (constant-level chamber) or the like.
For measurements of low turbidity (less than 200 mg/L), prepare a sampling system which can
supply the zero water (tap water ltered with a zero-turbidity lter).
1.1.2 TB400G-¨-¨-A1 (with sampling system, without
1-2
automatic cleaning or automatic zero calibration)
This is a system which combines the detector and converter with a sampling system to manually
supply process sample, zero water, and cleaning water (see subsection 2.6.1).
The measuring water ows into a header tank (constant-level chamber), serving also as a bubble
separation tank, after passing the ball valve located after the tap water inlet port.
Debubbled sample in this tank ow into the measuring cell in the detector at a constant owrate,
and drains through the drain outlet after overowing at the measuring cell.
The cleaning water passes the ball valve located after the tap water inlet port and ows into
the measuring cell in the detector from the cell side. The cleaning water then starts swirling
and removes dirt on the measuring cell wall. The dirt, together with the opening the ball valve
mounted under the header tank.
During zero check, the zero water is ltered by passing through a zeroturbidity lter from the tap
water inlet. This zero water ows into the measuring cell in the detector via the head tank through
a tube separate from that for the sample and drains through the drain outlet.
1.1.3 TB400G-¨-¨-A2 (with automatic cleaning and without automatic zero calibration)
This is a system which comprises the TB400G---A1 model with the automatic cleaning
function added (see subsection 2.6.2).
The sampling system of this system incorporates a solenoid valve at the cleaning water tube and
an electric motor-operated valve under the header tank. These provisions automatically clean the
measuring cell under the detector in a sequence preset in the converter.
IM 12E04A02-02E 9th Edition : Mar. 16, 2018-00
<1. OVERVIEW>
1.1.4 TB400G-¨-¨-A3 (with automatic cleaning and zero calibration)
This is a system which comprises the TB400G---A1 model with the automatic cleaning and
automatic zero calibration functions added (see subsection 2.6.3).
The sampling system of this system incorporates solenoid valves at the cleaning water tubing
and zero calibration tubing and electric motor-operated valves under the header tank and at the
measuring-water tubing. These provisions automatically clean the measuring cell in the detector
and perform zero calibration in a sequence preset in the converter.
1.2 Operating Principle
The operating principle of the Surface Scattering Light Turbidity Meter employs a method of
measuring the amount of the light scattering that takes place close to the surface of the water
sample. The measuring system comprises a detector and a converter. This section describes the
meter conguration and operating principle.
The detector is comprises a measuring cell and a detecting section. Sample that ows into the
measuring cell from the bottom of the cell overows at the top of the cell.
Meanwhile, a tungsten lamp closed inside the detector emits light onto the surface of the sample
through a system of lenses. This light is separated into scattered, reected, and transmitted
light on the water’s surface. The transmitted light and reected light are absorbed in a dark area
equivalent to a black body.
1-3
This scattered-light intensity (L) is proportional to the turbidity as shown here:
L = K • Q • S
Where K: a constant relative to turbidity,
S: turbidity,
Q: amount of light from the lamp.
The scattered light is detected by a turbidity element (a silicon photodiode). It is focused onto
the element with a lens inside the detecting section. This gives the scattered light signal to the
converter.
In addition, a reference element is incorporated in the detecting section to hold the amount a light
(Q) from the lamp constant, and it also provides a light-detection signal to the converter.
The measuring circuit of the converter is sealed in a housing of aluminum alloy together with the
operating panel and a terminal block for external wiring. This measuring circuit amplies and
calculates the input from the turbidity element in the detector and outputs a signal (1 to 5 V DC or
4 to 20 mA DC) corresponding to the measuring range.
The converter also calculates the reference element input from the detector to control the lamp
voltage so that the amount of light from the lamp is constant.

*1: A de-foaming tank (head tank) is to be provided. It is to be installed to adjust the sample ow to the detector at 1.5 to 2 L/min.
*2: These options are available for the specication of “without sampling system” (sufx code: -NN, -KC).
*3: These options are available for the specication of “with sampling system” (sufx code: -A1, -A2 or -A3).
*4: When measuring range is low (200 mg/L or less) and if air bubbles are likely to be formed on the sample, this option is to be specied.
When measuring range is high (more than 200 mg/L), this option is not to be specied. Because air bubbles in high ranges don’t disturb
the measurement, and because clogging or reduction of ow rate may occur at the removal port of air bubbles on the ow line.
*5: A pH meter with necessary units, or non-reagent type free available chlorine analyzer should be purchased separately.
Both of a pH meter and non-reagent type free available chlorine analyzer can not be installed together on the TB400G.
Available model & sufx codes are as follows;
Non-reagent type free available chlorine analyzer (refer to the GS 12F5A1-E)

3.1 Installation
3.1.1 Unpacking
The Surface Scattering Light Turbidity Meter is shipped only after being packed so as not to be
damaged during transportation. When the turbidimeter is delivered, unpack the meter carefully. If
the turbidimeter with a sampling system is delivered, unpack them near the location where they
are to be installed.
3.1.2 Installation Location
The Surface Scattering Light Turbidity Meter should be installed in a location where:
(1) rainwater cannot get inside, such as in a building or a cabinet,
(2) there is little vibration,
(3) corrosive gases are not present,
(4) there is low humidity,
3-1
(5) temperature changes are kept to a minimum and the temperature is maintained between -5
to 50 °C,
(6) there is enough clearance for maintenance and maintenance work can be easily done,
(7) drainage can be provided.
IM 12E04A02-02E 9th Edition : Mar. 16, 2018-00
<3. INSTALLATION, PIPING, AND WIRING>
3.1.3 Installation
Installation of the Surface Scattering Light Turbidity Meter differs depending on whether the
sampling system is provided or not. If the sampling system is provided, secure the entire system
with anchor bolts (M12 (12 mm) bolts) to a well-drained “concrete base”. If the sampling system
is not provided, mount the detector and converter onto pipes (2-inch pipe) or racks with the
special mounting bracket. (See Model Code Option Specication.)
In the case of TB400G---KC (for Korea), a noise lter assembly is attached. Please refer to a
gure of external dimensions for the attachment means of the noise lter assembly.

3.2 Piping
3.2.1 TB400G-¨-¨-NN, -KC (without sampling system)
(1) Measuring water piping
For a sample ow of 1.5 to 2 L/min, the sample can be introduced directly into the detector.
Connect the attached ø33 mm X ø25 mm black soft PVC pipe to the Sample inlet. However, if
the sample ow exceeds the range of 1.5 to 2 L/min, satisfy the ow condition by providing, for
example, a head tank (constant level tank) also used for bubble removal. In this case, also use
an ø33 mm X ø25 mm black soft PVC pipe for the piping connection between the head tank and
the detector.
(2) Drain piping
Connect an ø33 mm X ø25 mm black soft PVC pipe to the drain outlet of the detector. In doing
this, carefully run the piping so that a trip does not form in the pipe. If water is trapped in the drain
piping, the detector may be harmed by becoming ooded.
3-3
(3) Cleaning water piping
The cleaning water inlet of the detector is sealed with a blind plug.
Note: If a low turbidity (less than 200 mg/L) is to be measured, prepare a sampling system which allows a supply of zero water (tap
water ltered with a zero-turbidity lter).

3.2.2 TB400G-¨-¨-A1, -A2, and -A3 (with sampling system)
(1) Sample-water piping
This is piping to supply sample to the detector. The pressure and ow rate for the Sample are 20
to 500 kPa and 2 to 10 L/min, respectively. Piping connections are designed for a rigid PVC pipe
of nominal size VP16 (ø22 mm). Do the piping using any anges or unions conforming to the pipe
diameter.
(2) Tap-water piping
This is piping to supply cleaning water and zero water to the detector. Supply water having a
turbidity of 2 mg/L or less, such as tap water. The pressure of the water to be used is 100 to 500
kPa. Piping connections are designed for a rigid PVC pipe of nominal size VP16 (ø22 mm). Do
the piping using any ttings conforming to the pipe diameter similar to the piping for sample.
Note: Please consider to install a check valve so that cleaning water does not ow backward in the tap water side.
(3) Drain piping
This is piping for draining the sample and tap water supplied to the detector to a drain or the like.
The piping connection is designed for a rigid PVC pipe of nominal size VP40.
3-4
Connect such a pipe of nominal size VP40 (VU40) or more and do the piping so that debris does
not remain or get trapped or get trapped in the pipe.

Use a two-conductor cable having a nished of ø6 to ø12 mm (/ARS : The occasion with the
arrester ø9 to ø11 mm) for the power wiring.
The cable end-treatment procedure for the end to be connected to the converter is described in
the following:
(1) Strip off about 80 mm of the cable insulation covering from the end.
(2) Attach clamp terminal lugs tted to M4 (4 mm) screws to the tips of the conductors.
In the case of TB400G---KC (for Korea), please wire a noise lter assembly by all means.
[Grounding Wiring]
Do the grounding wiring using the grounding terminal at the bottom of the converter case.
As the grounding terminal is for an M5 (5 mm) screw, connect a grounding conductor whose
end is end-treated (obtaining sufcient continuity) and do the grounding (JIS class D, grounding
resistance of 100 ohms or less).
3-7
Note: If grounding cannot be done using the ground terminal of the converter case, connect
the grounding conductor to terminal G (M4 (4 mm) screw) within the converter and ground the
conductor on the power supply side. In this case, use 3-conductor or 2-conductor shielded cables
for the power and grounding wiring.
Do not use two-point grounding.
3.3.2 Analog Output Wiring
This is the wiring for transmitting a 1 to 5 V DC or 4 to 20 mA DC output signal corresponding
to the output range to a receiving instrument such as a recorder. For Wiring, use a 2-conductor
shielded cable of nished ø6 to ø12 mm (/ARS : The occasion with the arrester ø9 to ø11 mm).
The cable end-treatment procedure and connection procedure on the connecting side to the
converter are shown below.
(1) Strip off about 40 mm of the insulation covering and shield from the cable end and solder a
leadwire to the root of the exposed shield. Protect the soldered part with wound a insulation
tape.
(2) Make the soldered leadwire length almost the same as other conductor lengths and attach
crimp terminal lugs conforming to as M4 (4 mm) screw to the tips of each conductor and this
leadwire.
(3) Connect the cable to the converter terminals + and -. Connect the plus pole conductor to
the OUTPUT “+” terminal and the minus pole conductor to the OUTPUT “-” terminal. Also,
connect the leadwire of the shield to terminal G. (Do not ground the shield on the receiving
side.)

3.3.3 Digital Output Wiring
This is the wiring for outputting turbidity signals and generated failure details as digital signals
(through RS-232C). For details of specications and transmission, see Section 2.1, “Standard
Specications”.
For wiring, use a 3-conductor shield cable of nished ø6 to ø12 mm. Limit the cable length up 10 m.
The cable end-treatment procedure and connection procedure on the connecting side to the
converter are shown below.
(1) Strip off about 40 mm of the insulation covering and shield from the cable end and solder a
leadwire to the root of the exposed shield. Protect the soldered part with wound insulation
tape.
(2) Make the soldered leadwire length almost the same as other conductor lengths and attach
crimp terminal lugs conforming to an M4 (4 mm) screw to the tips of each conductor and this
leadwire.
(3) Connect the cable to the converter terminals (TD, RD, DG, and G). Connect the conductors
as shown in Figure 3.7 (Do not ground the shield on the receiving side).

3.3.4 Contact Input and Contact Output (Range Output) Wiring
As output ranges, three types of ranges can be set, and output can be obtained by freely
switching these ranges. The output range selection is “remote”, “local” or “auto” mode.
This wiring is applied if the range is changed in “remote” mode (see Section 6.6 (12)) or the range
contact output is used.
Use a 2-conductor cable of nished
ø
6 to ø12 mm for the wiring. However, use a 3-conductor
cable when remote range selection only is used and a 4-conductor cable when only range
contact output is used.
The on and off contact statues are identied with the resistance value conditions shown in Table
3.1. In doing wiring, conrm that a contact meeting these conditions is used.
Table3.1 On/offIdenticationofContactInputforSwitching“Remote”Range
Onstatusidentication Offstatusidentication
Resistance value (contact) 200Ω or less 100 kΩ or more
The cable end-treatment procedure and connection procedure on the converter connection side
are shown below.
(1) Strip off about 40 mm of the cable insulation covering from the end and attach suitable
terminal lugs tted to M4 (4 mm) screws to the tip of each conductor.
(2) Connect the cable conductors to “remote” range selection terminals R1, R2, and R3 and
range contact output terminals A1, A2, A3 and S4.
“Remote” range switching on/off contact input is performed between terminals R1 and R2, and
between terminals R1 and R3 (See gure 3.8). The relationship between the on/off contact input
and the output range is as shown in Table 3.2.

3.3.5 Contact Output Wiring
The converter outputs contact signals for failure, maintenance, and upper and lower limit alarm
or automatic cleaning/in calibration. Use a nished
4-, or 6-conductor cable depending on the number of contact outputs used). The contact rating
for contact output relays is as shown in Table 3.3. For the instrument to be connected, select that
which satises the conditions in Table 3.3.

4.2.2 Automatic Cleaning Operation
When automatic cleaning is specied (Sufx code: -A2 or -A3), the detector is automatically
cleaned in the <MEAS.> mode. With measuring water (or zero water) owing, dirty substances
on the measuring cell wall and the measuring surface edge are washed out by jets of cleaning
water (tap water) from two outlets on the side of the measuring cell in the detector. After cleaning,
dirt on the measuring cell, header tank, and in the piping between the header tank and the
detector is washed out by opening the drain outlet of the header tank.
The above cleaning operation is repeated a predetermined number of times.
The information of start or end is output when automatic cleaning is started or ended.
In addition, there are two types depending on the specications for automatic cleaning.
• Withoutautomaticzerocalibration(Sufxcode:-A2)
• Withautomaticzerocalibration(Sufxcode:-A3)
The explanation for each types are followed.

4.2.3 Automatic Zero-calibration Operation
If the specications including automatic zero calibration (Sufx code: -A3) are used, zero
calibration is automatically performed. The automatic zero-calibration computation is
implemented by passing zero water and at a stabilized indication after performing the same
cleaning operation as automatic cleaning in subsection 4.2.2 b.
In addition, at the start and end of automatic zero calibration, all starting and completing digital
information is output (see digital communication specications in Section 2.1).
Automatic zero calibration can be started in the following two ways.
• Startup with the internal timer (see Figure 4.7).
• Startup with FUNCTION “7” in the <MAINT.> mode (see Section 6.5).
Note: Startup with the internal timer can be selected for execution (on)/stop (off) using FUNCTION “B.” in the <PROGRAM1> mode. It
has been set to execution (on) when shipped from the factory.

(2) Output range 2: Range contact outputs A1 and A3 are closed; RNG2 lamp is lit.
(3) Output range 3: Range contact outputs A1 and A4 are closed; RNG3 lamp is lit.
• When the output range is switched, digital range information is output only once (see Section 2.1, "Digital Communication
Specications").
• When the turbidimeter is used with auto-range, the output should be set as shown below.
(1) Set the Low side of the setting to 0 (display is "L00.00").
(2) Set the High side of the setting so that range 1 <= range 2 <= range 3 holds.
(3) If two ranges are required, set range 2 = range 3.
(4) If one range is required, set range 1 = range 2 = range 3.
• Range switching timing in auto-range should be taken as follows:
(1) The timing of switching from a low range to a higher range is a point where the measured value just becomes larger than the
auto-range switching point of the lower range.
(2) The timing of switching from a higher range to a lower range is a point where the measured value just becomes smaller than
-10% of the auto-range switching point in the lower range (10% is provided for range switching hysteresis).
Note: Auto-range switching should be set in item 7. When the turbidimeter is shipped from the factory, this is set to 80% of the range.
• In auto-range, the output ranges are switched for contact inputs (R1, R2, and R3).
(1) No contact input: Output range 1
(2) Contact input (R1, R2) = Closed: Output range 2
(3) Contact inputs (R1, R3) = Closed: Output range 3

5.6.1 OverviewoftheSpikeDetectionFunction
If air bubbles occur or dust is present on the sample surface of the detector's measuring cell at
which the light is scattered, the reading, in general, rises rapidly. The uctuation is dependent on
the size of air bubbles or dust and their behavior on the sample surface.
A head tank is supplied when the TB400G with a sampling system is specied. It is for removing
air bubbles and thus for preventing them from reaching the detector. In rare cases, however,
air bubbles occur and grow in the pipe between the head tank and the detector, and rise to the
surface of the measuring cell, resulting in reading uctuation.
The converter has a signal averaging function with a user-congurable averaging factor.
Small changes in readings due to air bubbles or dust can be compensated for, to some degree,
by increasing the averaging factor. However, it is not practical to set the averaging factor too high
because it can cause a delay in the response of the turbidity signal.

The spike detection function is the one of detecting and suppressing a rapid change due to air
bubbles or dust, preventing it from affecting the reading and output. (Note that this function is
available in models with ROM number K9410SE with version 1.04 or later).
IM 12E04A02-02E 9th Edition : Mar. 16, 2018-00
<5. FUNCTIONS>
How It Functions
To suppress a rapid change due to air bubbles or dust, the TB400G:
• Checks a turbidity signal before averaging;
• Calculates the difference between the current signal and the previous signal;
• Compares the difference with the Detection Level;
• If it is less than the Detection Level, proceeds to averaging and gives the turbidity reading;
• If it is greater than the Detection Level, holds the output for a specied Hold Time period;
• During that period, suspends the Detection Level check;
• After the Hold Time has elapsed, averages signals without the Detection Level check for a
specied Sampling Time period and gives turbidity readings; and,
• After the Sampling Time has elapsed, performs the Detection Level check again.
Instructions for Use
The spike detection function is effective in processes where turbidity changes are relatively small
under normal conditions, but it may not be suitable for processes where rapid changes occur
often. Even if rapid changes do not usually occur, this function may be activated and may cause
a delay in the response of the reading or output if stepwise turbidity changes occur occasionally.
Therefore, before using this function process conditions should be carefully considered, and in
order to use it properly, determine optimum setpoints for the operating conditions while changing
them little by little.
5-10
When using the function, pay attention to the following.
• Adjust the Detection Level according to the degree of reading change due to air bubbles or dust.
• If an excessively long Hold Time is set, the turbidimeter may not be able to detect a change
in reading that may have occurred and should have been recognized as a real change.
• If the function is responsible for the delay in the response of the turbidity reading, try setting
the Sampling Time longer without changing the Hold Time.
• When an abnormal turbidity reading is suspected, turn off the function once and wait for
a while and see. The function may have prevented the turbidimeter from giving readings
properly.
5.6.2 SettingsofSpikeDetectionFunction
To enable the function, set necessary parameters in <PROGRAM1> mode following the
procedure below.
• Turn ON the function (FUNCTION “F.”)
• Set the Detection Level (FUNCTION “D”)
• Set the Hold Time (FUNCTION “E”)
• Set the Sampling Time (FUNCTION “F”)
a.DetectionLevel(%)
The Detection Level is a value used to determine whether a reading is a spike due to air bubbles
or dust or not. It is dened as a percentage of the upper limit of the analog output range currently
selected. The percentage setpoint is converted to the corresponding turbidity signal in the
computer. (The ratio of the sensitivity correction factor is also calculated automatically).
For the Detection Level check, a pre-averaging turbidity value is used. To determine the
Detection Level, it may be needed to know the degree of uctuation in pre-averaging turbidity
signals. Set the averaging factor to 1 in FUNCTION “4” in <PROGRAM1> mode to allow the
turbidimeter to give turbidity readings directly without averaging.
Check readings to know the degree of uctuation. Generally, the Detection Level is set to a value
greater than the uctuation.
IM 12E04A02-02E 9th Edition : Mar. 16, 2018-00
<5. FUNCTIONS>
b. Hold Time
When a signal exceeds the Detection Level, the readings and output signals are held for a
specied Hold Time. The Hold Time should be long enough for air bubbles and dust to move
away from the sample surface. Normally, air bubbles and dust will run off the sample surface or
disappear within a short time (in a few seconds). In practice, rst set the Hold Time to a shorter
time, and then increase it if the function does not work satisfactorily.
c. Sampling Time
After the Hold Time has elapsed, the turbidimeter gives readings without any processing for a
specied Sampling Time to verify that no uctuation occurs in turbidity readings.
The time count begins after the Hold Time. It is unlikely that air bubbles or dust occur
consecutively. Therefore, the Sampling Time may not need to be too short. If the Sampling Time
is set too short, the response is delayed when a sudden change in turbidity actually occurs. First
set the Sampling Time slightly longer. If something is wrong with the behavior of the function,
shorten the time. For the procedure for settings in <PROGRAM1> mode, refer to Section 6.6.
Instructions for Use
Be careful when using the function as the following restrictions apply.
• The function works only in <MEAS.> mode. As soon as the mode is changed, the Hold or
Sampling timer is reset and the function stops working.
• The function does not work during automatic zero calibration or automatic cleaning.
If automatic zero calibration or automatic cleaning begins when the function is active (i.e.,
during a Hold Time or Sampling Time period), the function immediately stops running and
the timer is reset.
• During a Hold Time period, both turbidity readings (including communication data) and
analog outputs are held.
• The function does not run for approximately 5 seconds right after the turbidimeter is turned
on.
• If the turbidimeter is turned off then on again while the function is running, the timer is reset.
• Since the reference clock runs at a period of approximately 1.07 seconds, the actual time
are slightly greater than their setpoints, respectively. For example, if the time is set to 10
seconds, the actual time will be: 10 x 1.07 = approximately 11 seconds.

6.2 Operation Modes and Functions
Operation of the turbidimeter is divided principally into three operation modes (modes are
classied into four types).
(1) Measurement mode (<MEAS.> mode) (subsections 6.2.1)
(2) Maintenance mode (<MAINT.> mode) (subsections 6.2.2)
(3) Setting modes
• Data setting/operation setting mode (<PROGRAM1> mode) (subsections 6.2.3)
• Automatic cleaning and zero-calibration setting/failure detection function selection mode
(<PROGRAM2> mode) (subsections 6.2.4)
Display or setting items for data and command items, such as for calibration, are determined by
functions in each mode. Accordingly, various operations require designation of a mode and a
function code.
Table 6.2 outlines the modes and the function codes in each mode. For details on function codes,
see subsections 6.2.1 to 6.2.4.

6.3.3 Numerical Input
Numerical input is made with the data set keys. Operation of the data set keys becomes effective
in the modes other than the <MEAS.> mode. The data set keys include the following four keys.
(a)[>]Key(Digitselectionkey):
This is used select the digits of a value of displayed data in the data display that are to be
changed. Digits are selected in such a manner that a digit to be changed moves one place to the
right from the most signicant digit on the left every time this key is pressed and returns to the left
end from the right end.
When the display is on or off in each mode, pressing the [>] key indicates them alternately. Also,
when the display comprises _ _1, _ _2, and _ _3, pressing the [>] key indicates one of them in
this order.

(1) Zero Calibration (with "zero water") [FUNCTION "1"]
The zero-calibration operation using "zero water". For the value operating procedures, see
Section 7.6.
The following is a description of the key operations.
(Example of display)
(1) Select FUNCTION "1" in the <MAINT.> mode. => 000.04 mg/L
(2) Press the [ENT] key after the display becomes => The "CAL" lamp begins to ash.

(3) Press the [>] key. => 000.00 mg/L is displayed.
(4) Press the [ENT] key to terminate calibration. => 000.00 mg/L
The entire display ashes once and the "CAL" lamp goes out.
In addition, at operation 4, the measured signal at the zero point is checked and if the permissible
range (-10 to 10 mV) is exceeded, Err21 (zero calibration overrange) is displayed (see Section
5.3 *3). In this case, the "FAIL" lamp is not lit and a FAIL contact is not output.
An error message can be reset by pressing the [ENT] key and the display returns to the turbidity
indication. Wait until the display becomes stable and then begin from step 2 again.
At any stage of zero-calibration operation, pressing the [MODE] key or [FUNC] key allows
switching to another mode or function. Calibration computation is not performed unless the
operation of 4 is carried out.
Note: At this calibration, the turbidity not multiplied by the correction factor from the zero-shift calibration (zero correction) in (3) or span
calibration (sensitivity correction) in (5) is displayed.
(2) Zero Calibration (with lamp turned off) (FUNCTION "2")
The zero-calibration operation is done by automatically turning off the lamp. Only in a measured
turbidity exceeding 200 mg/L, can zero calibration be performed simply in the following
operations. A turbidity reading with the lamp turned off reads a value 1 mg/L smaller than a
reading using "zero water".
IM 12E04A02-02E 9th Edition : Mar. 16, 2018-00
<6. PROCEDURES FOR CONVERTER OPERATION>
(Example of display)
(1) Select FUNCTION "2" in the <MAINT.> mode. => 002.00 mg/L

becomes stable, and press the [>] key.
(4) Press the [ENT] key to calibrate. => 000.00 mg/L
The entire display ashes once and
then the CAL lamp goes out.
In addition, at operation 4, the zero-calibration range is checked and the permissible range (-10
to 10 mV) is exceeded, Err21 (zero-calibration overrange) is displayed (see Section 5.3 *3). In
this case, the "FAIL" lamp is not lit and a FAIL contact is not output.
The error message can be reset by pressing the [ENT] key and the display returns to the turbidity
indication. Wait until the display becomes stable and then begin from step 2 again.
In any stage of zero-calibration operation, pressing the [MODE] key or [FUNC] key allows
switching to another mode or function. Calibration computation is not performed unless
operation of 4 is carried out. Also, since the lamp voltage returns to the control voltage when
the turbidimeter resets from the function for calibration with the lamp turned off, a little time is
necessary until the turbidity reading becomes stable. When the mode is to be changed to the
<MEAS.> mode, change the mode after waiting for ve minutes or more.
Note: At this calibration, the turbidity not multiplied by the correction factor from the zero-shift calibration (zero correction) in (3) or span
calibration (sensitivity correction) in (5) is displayed.

(3) Zero-shift Calibration (FUNCTION "3")
At any turbidity value, this is an operation to zero-shift a turbidity reading within the permissible
range (±9 mg/L).
For details on the function, see Section 5.3 (*3). The zero-correction factor obtained in this
calibration can be displayed and directly changed in FUNCTION "B" in the <PROGRAM1>
mode.
The operation procedures are as follows.
(Example of display)
(1) Select FUNCTION "3" in the <MAINT.> mode. => 000.13 mg/L
(2) Wait until the display becomes stable, and => 000.13 mg/L
then press the [ENT] key. The CAL lamp ashes.
(3) Press the [>] key. => 00000. mg/L
The display is now ready for
determination of the decimal point
position.
(4) Press the [>] key to determine the position => 000.00 mg/L
of decimal point.
Every time the key is pressed, the decimal
point moves to the right and when the least
signicant digit is reached, the decimal point
then moves to the second digit from the left.
(5) Press the [ENT] key. => 000.00 mg/L
The second digit from the left ashes
and waits for the turbidity setting.

<6. PROCEDURES FOR CONVERTER OPERATION>
(6) Select a digit with the [>] key and set the => 000.22 mg/L
turbidity value using the [^] or [v] key.
Every time [>] key is pressed, the ashing digit
moves to the right and when the least
signicant digit is reached, it moves to the
second digit from the left.
(7) Press the [ENT] key to terminate calibration. => 000.22 mg/L
The entire display ashes once and
the CAL lamp goes out.
In addition, if the turbidity value set in operation 7 exceeds the permissible setting range (0
to 2200 mg/L), "not" is displayed. As this setpoint is out of range, reset the error message by
pressing the [>] key and continue the operation from step 2.
Also, check the zero-correction factor; if it exceeds the permissible range (±9 mg/L), "Err23" is
displayed. In this case, the "FAIL" lamp is not lit and a FAIL contact is not output. Reset the error
message by pressing the [ENT] key and continue operations from step 2.
At any stage of zero-shift calibration operation, pressing the [MODE] key or [FUNC] key allows
switching to another mode or function. Calibration computation is not performed unless operation
7 is carried out.
(4) Span Calibration (by standard solution or calibration plate)
(FUNCTION "4")
6-13
This is the operation for normal span calibration (by the calibration plate or standard solution). For
details on value operation and others, see Sections 7.6 and 7.7. Select whether the calibration
plate or standard solution is used in span calibration in FUNCTION "D" in the <PROGRAM1>
mode.
The following is the key operation procedure.
(a) Span calibration with calibration plate
(Example of display)
(1) Select FUNCTION "4" in the <MAINT.> mode. => 0090.5 mg/L
(2) Wait until the display becomes stable, and => 0090.5 mg/L
then press the [ENT] key. The CAL lamp ashes.
(3) Press the [>] key. => 0090.0 mg/L
The preset turbidity value of the
calibration plate is displayed.
(4) Press the [ENT] key to terminate calibration. => 0090.0 mg/L
The display ashes once and the CAL
lamp goes out.
In operation 4 check the difference between the current turbidity value and the calibration plate
turbidity value. If it exceeds the permissible range (±50% of the preset calibration plate turbidity
value), "Err24" is displayed. In this case, the "FAIL" lamp is not lit and a FAIL contact is not output.
Reset the error message by pressing the [ENT] key, check that the calibration plate is set in place
and continue operation from step 2.
Also, check the ratio of the current sensitivity (slope) to the reference sensitivity. If the exceeds
the permissible range (50 to 400%), "Err22" is displayed (see Section 5.3 *3).
The error message is reset by pressing the [ENT] key. Perform operation from step 2 again.
At any stage of zero-shift calibration operation, pressing the [MODE] key or [FUNC] key allows
switching to another mode or function. Calibration computation is not performed unless operation
4 is carried out.
Note: At this calibration, the turbidity not multiplied by the correction factor from the zero-shift calibration (zero correction) in (3) or span
calibration (sensitivity correction) in (5) is displayed.
