1. EXPLOITATION NOTICES

Dear User!

We present you a device distinguished by accuracy according to the
technical data and by a high stability of displayed results. We believe that
measurements will not cause you any trouble and that the meter will operate
without any inconvenience.
Using good-quality cells and replacing them if necessary ensures obtaining
high measuring parameters. We want to call your attention to the fact, that
this equipment has much shorter working life than the meter.
In case of conductivity measurements it is important to choose the cell with K
constant value adjusted to the measuring range. Improper selection may
cause increase of the readout error.

The essential feature of our products is their low failure frequency. However,
if your meter fails, our firm will immediately perform its warranty repair.

We wish you pleasant and trouble-free work with our meter.

2. CHARACTERISTICS OF THE METER

The CC-411 conductivity meter belongs to the newest generation of
measuring devices which ensure high accuracy and repeatability of readings
and is easy in use. Two kinds of power source: battery and power adapter,
enable work in the field and long-lasting measurements in the laboratory.
Electronic elements of the newest generation used in the meter have made
its memory independent from power supply and have ensured very low
power consumption what greatly prolongs the operation time on 1 battery.
The meter is equipped with large custom LCD display, which displays the
conductivity or the temperature value. Waterproof housing makes working in
difficult conditions possible. Minimised size and weight make the meter very
handy especially during the field work.

Main features of CC-411 are:

- high accuracy and stability of readings;

- calibration of the conductivity cell by introducing the K constant or on

standard solutions;

- possibility of determining the K constant of the cell;

- automatic and manual temperature compensation;

- storing parameters in non-volatile memory;

- co-operation with Pt-1000 temperature sensor;

- system protecting the meter against damages caused by connecting the

battery inversely;

- information about the battery condition (

)

;

- automatic switch off function.

3. WHAT IS THE METER DESIGNED FOR

CC-411 waterproof conductivity meter is a precise and easy-to-use meter

designed for measurements of conductivity in µS/cm or mS/cm. The meter
may be also used for accurate temperature measurement of solutions and air
in °C. It is useful both for work in the field and measurements in the
laboratory.
Waterproof housing enables work in difficult weather conditions or in humid
environment.
The CC-411 conductivity meter is used in food, chemical, pharmaceutical and
power industries, in water treatment stations, laboratories, agriculture,
universities, scientific laboratories etc.
The meter is prepared to work with many types of conductivity sensors (with
wide ranged K constant) equipped with BNC-50 connector. CC-411 co­operates with Pt-1000 temperature probe with Chinch connector.

4. THE OUTSIDE VIEW

On the front wall of the meter there is an LCD display (Pic.1) on which,
depending on the chosen function, the result of conductivity measurement in

µS/cm or mS/cm or temperature measurement in oC is displayed:

A particular function is chosen by pressing the button.
Symbols of units are displayed next to the result.
In case of disconnecting the temperature probe the meter switches to the
manual temperature compensation mode. Next to the result there will be

displayed blinking symbol. If the battery should be changed, a
symbol is displayed. The keyboard placed under the display is used for
switching the meter on and off, choosing the measuring function, calibration
and entering parameters.

Pic.1

The CAL symbol on the left side of the display informs that the meter is in
calibration mode.

The keyboard (pic. 2) placed under the screen has the following keys:

- switching the meter on and off.

- pressing shortly enters the unit choosing mode (with the
button); pressing and holding returns to the measurement
mode.

- holding this button enters the calibration mode (CAL symbol
displayed).

, - buttons used for entering the parameters

In the upper wall of the meter there are inputs placed with the symbols given
below:

F1 - BNC-50 input for connecting the conductivity cell;
t - Chinch input for connecting the temperature probe;
P - the power adapter input.

5. SWITCHING THE METER ON AND OFF

After switching it on with the

button, the meter tests the memory and the

display on which all symbols are displayed after switching it on (Pic. 3).

Pic. 3

If the test ends successfully, after about 1.5 s the meter switches
automatically to the measuring mode, in which it was switched off. If a

sign is displayed, it means that the meter has lost the factory settings and
requires service repair. If after 1,5 s all symbols are continuously displayed, it
informs that the calibration parameters of the cell have been lost.

After pressing the button the meter adopts the K constant of the
conductivity cell K=1.000 cm-1 and enters to the measuring mode. It will be
necessary to calibrate the conductivity cell.

The meter is switched off by pressing the

button. In case of working on
batteries, in order to save them, the meter switches automatically off after 10
minutes of non-use. This function is automatically deactivated when working
with power adapter.

6. PREPARATION TO WORK

Before starting measurement:

- connect the power adapter plug to the P input, if work with the power
adapter is planned;

- join the suitable conductivity cell to BNC-50 input (F1);

- in case of using the temperature probe it should be connected with the

temperature input Chinch (t);

- switch the meter on by pressing the button.

6.1. Choosing the measuring function and unit

CC-411 enables measurement of:

- conductivity at µS/cm or mS/cm converted to 25oC;

- salinity in g/l converted to NaCl (accordinfg to actual slope);

- salinity in g/l converted to TDS (with use of the W

TDS

coefficient);

- conductivity of honey at µS/cm or mS/cm converted to 20oC;

The unit is chosen in the measuring mode by pressing and holding the
button, in the buttom row displays the symbol and in the upper row -

the (conductivity) symbol (Pic.4). Next, by pressing the

button,

choose:

- - measurement in µS/cm lub mS/cm converted to 25oC;

- - measurement in g/l converted to NaCl;

- - salinity in g/l converted to TDS;

- - measurement in honey in µS/cm or mS/cm converted

to 20oC.
