Introduction
(a)Thank you for your purchase of our product. The Model MBM-102A Electrodeless Concentration
Analyzer / Controller (hereafter called the controller or the product) is an indicating controller in a
measurement system that measures the electrical conductivity of a solution continuously using the
electromagnetic induction method and converts the measured value into concentration value and
then displays and outputs its concentration value.

Example of a Measurement System
(b)If the product is equipped with an RS-232C connector (option), the following can be performed
from the PC screen by using an application program (option). For details, refer to the instruction
manual of the application program.
•Import the digital measured value data (concentration, temperature and conductivity) to the PC.
•Change the concentration conversion data stored in the controller (using an optional dedicated
software program).
(c)The concentration conversion data (linear approximate expression) determined by the ordered
specification is preinstalled in this product. The concentration conversion data represents the
relationship between concentration, temperature and conductivity. For standard specification, the
concentration conversion data is based on the International Critical Table (I.C.T.) and DKK-TOA
analysis data.
(d)The entire concentration measuring range is 0.00 to 99.99% (it may be 0.000 to 4.000% depending
on how the setting is made). However, the concentration measuring range of each product depends
on the preset concentration conversion data. In accordance with the preset concentration
conversion data, one of the following conductivity measuring ranges is automatically selected.
0.000 to 2.100/ 0.00 to 7.00/ 0.00 to 21.00/ 0.0 to 70.0/ 0.0 to 210.0/ 0 to 700/ 0 to 2100mS/cm
(at 25°C)
The transmission output range can be set arbitrarily based on the range of the concentration
conversion data.
(e)This product can be combined with a sensor whose reference cell constant (designed cell constant)
is 9.00 or 2.60/cm (depending on the ordered specification). Sensors with other reference cell
constants cannot be combined. Power supply is 90 to 264VAC and two circuits are provided for
alarm outputs. For other specifications, refer to 7.1 “Standard Specifications”.
(f) There is a possibility that the product indicates or outputs an erroneous measured value by the
following causes. Prepare a backup system so that no damage occurs to the related facilities even
in the case like these.
•Any problem of the product such as deterioration or damage of the detecting section or
inappropriate insulation of cables.

•Improper setting of operating conditions or calibration operation.
•Electrical interference such as noise in the vicinity or improper grounding.
•Other unpredictable phenomena
(g)Since important items are described in “Safety Information”, read the contents carefully.
(h)The product should be handled by persons who have received proper training. In addition, for
technical services such as repairs, ask a specialist to do who is qualified for the technical
certification system in our company or a person who has technical skills equivalent to that
certification system.

Safety Information
(1) Meaning of markings
Meaning of symbols such as the ones used in notations of warning in the instruction manual is
described below. In addition, the alert symbol ( : General caution symbol) used on a product label,
etc. is meant to notify the existence of hazard/loss and it also means “Refer to the Instruction
Manual”.
:
Indicates the degree of hazard which can lead to death or serious injury if you fail to operate the
product properly.
Serious injury means an injury such as loss of sight, burns (high temperature or low temperature),
electric shock, bone fracture and poisoning, and the aftereffects of the injury remains or the injury
requires hospitalization or long periods of outpatient treatment.
:
Indicates the degree of hazard/loss which can result in minor injury or property damage if you fail to
operate the product properly.
Minor injury means an injury not requiring hospitalization or long periods of outpatient treatment.
Property damage refers to damage that affects property around the product such as equipment and
buildings (wide-ranging damage).
【IMPORTANT】:Indicates important matters such as to prevent damage to the product main body,
prevent data destruction, prevent wasting time, and maintain performance.
〔NOTE〕 :Indicates comments, reasons, background information, a case example and other
items to help the reader understand the meaning.
:Indicates reference items.
①, ②, ③:Indicates item numbers such as the ones used in operations.
(2) Safety compliance items
Hazardous Gasses
Do no use the product in an area where explosive gas, flammable gas exists. Using
the product in any of these areas can cause explosion or fire.
Electric Shock
Do not touch the terminals in the analyzer while power is applied. Touching the
terminals may cause electric shock.
The ground terminal must be grounded. If the terminal is not grounded and a problem
occurs in the power supply system, electric shock may result.

2.1 Operation Start Procedure
Follow the procedure below, and then the controller can be placed in normal operation.
①Check the installation. ⋅⋅⋅⋅⋅⋅ Check that the necessary installation work (mounting and wiring) is
completed. 8. “Installation”
②Immerse the sensor in sample solution. ⋅⋅⋅⋅⋅⋅ Make sure that the sensor is installed properly and
the liquid-contact part of the sensor is immersed in sample solution.
③Supply power. ⋅⋅⋅⋅⋅⋅ Make sure the power to be supplied to the controller is of the power voltage
within the range described on the nameplate of the product or in the specification and then turn on
power.
Electric Shock
Do not touch the terminals in the analyzer while power is applied. Touching the
terminals may cause electric shock.
•When power is supplied, “Concentration measured value” screen, the initial screen of the
measurement mode (“ST-BY” is unlit), appears and the concentration measured value is shown
on the main display.

•Normally, the transmission output range is set in accordance with the ordered specification when
the product is shipped from the factory.
⑥Check the 20mA transmission value. ⋅⋅⋅⋅⋅⋅ Press once and check that the value on the
main display of “Transmission 20mA value display (20mA)” screen shows the necessary
concentration value (%) that corresponds to 20mA value. Check that the transmission output range
is appropriate for the conductivity of sample solution for 20mA value as well as 4mA value.
•The transmission output range can be changed. 3.3(5) “Setting the transmission output
