1Safety
This operating manual contains basic instructions that you must follow
during the commissioning, operation and maintenance of the meter.
Consequently, all responsible personnel must read this operating man-
ual before working with the meter.
The operating manual must always be available within the vicinity of the
meter.
Target group The meter was developed for work in the field and in the laboratory.
Thus, we assume that, as a result of their professional training and
experience, the operators will know the necessary safety precautions
to take when handling chemicals.
Safety instructions Safety instructions in this operating manual are indicated by the warn-
ing symbol (triangle) in the left column. The signal word (e.g. "Caution")
indicates the level of danger:
Warning
indicates instructions that must be followed precisely in order to
avoid possibly great dangers to personnel.
Caution
indicates instructions that must be followed precisely in order to
avoid the possibility of slight injuries or damage to the instrument
or the environment.
Further notes
Note
indicates notes that draw your attention to special features.
Note
indicates cross-references to other documents, e.g. operating manu-
als.

1.1 Authorized use
Authorized use of the meter consists exclusively of the measurement
of conductivity, resistivity, salinity, TDS (total dissolved solids) and tem-
perature in a laboratory or field environment.
The technical specifications as given in chapter 3 TECHNICAL DATA must
be observed. Only the operation and running of the meter according to
the instructions given in this operating manual is authorized.
Any other use is considered unauthorized.
1.2 General safety instructions
This meter is constructed and tested in compliance with the IEC 1010
safety regulations for electronic measuring instruments.
It left the factory in a safe and secure technical condition.
Function and
operational safety
The smooth functioning and operational safety of the meter can only be
guaranteed if the generally applicable safety measures and the specific
safety instructions in this operating manual are followed during opera-
tion.
The smooth functioning and operational safety of the meter can only be
guaranteed under the environmental conditions that are specified in
chapter 3 TECHNICAL DATA.
If the meter was transported from a cold environment to a warm envi-
ronment, the formation of condensate can lead to the faulty functioning
of the meter. In this event, wait until the temperature of the meter
reaches room temperature before putting the meter back into opera-
tion.
Caution
The meter is only allowed to be opened by authorized personnel.

Safety CO 3100 H
8ba77074e05 05/2021
Safe operation If safe operation is no longer possible, the meter must be taken out of
service and secured against inadvertent operation!
Safe operation is no longer possible if the meter:
has been damaged in transport
has been stored under adverse conditions for a lengthy period of
time
is visibly damaged
no longer operates as described in this manual.
If you are in any doubt, please contact the supplier of the meter.
Obligations of the
purchaser
The purchaser of this meter must ensure that the following laws and
guidelines are observed when using dangerous substances:
EEC directives for protective labor legislation
National protective labor legislation
Safety regulations
Safety datasheets of the chemical manufacturers.
Caution
In addition to the safety instructions mentioned here, also follow
the safety instructions of the sensors used.

Alternatively, you can also use Ni-MH rechargeable batteries (type
Mignon AA). In order to charge the batteries, an external charging
device is required.
4.2.2 Switching on the meter
Note
The meter has an energy saving feature to avoid unnecessary battery
depletion.
The energy saving feature switches off the meter if no key is pressed
during the adjusted interval. (How to set the switch-off interval, see sec-
tion 5.3.1).
4.2.3 Setting the date and time
3Place four batteries (type Mignon AA) in the battery compart-
ment.
4 Close the battery compartment.
1Press the <On/Off> key.
The meter performs a self-test.
The display shows the manufacturer's logo while the self-test
is being performed.
Subsequently, the meter switches to the measuring mode
(measured value display).

Switching off Press the <On/Off> key.
Automatic switch-off
function
The instrument has an automatic switch-off function in order to save the
batteries (see section 5.3.1). The automatic switch-off function
switches off the meter if no key is pressed for an adjustable period.
The automatic switch-off function is not active
if the communication cable is connected
if the Automatic data storage function is active, or with automatic
data transmission
Display illumination The meter automatically switches off the display illumination if no key
is pressed for 30 seconds. The illumination is switched on with the next
keystroke again.
You can also generally switch the display illumination on or off (see
section 5.3.1).

navigation
An overview of the operating modes and navigation of the CO 3100 H
is given in section 5.2.1 and section 5.2.2.
5.2.1 Operating modes
The instrument has the following operating modes:
Measuring
The measurement data of the connected sensor are shown in the
measured value display
Calibration
The course of a calibration with calibration information, functions
and settings is displayed
Storing in memory
The meter stores the measurement data manually or automatically
Transmitting data
The meter transmits measurement data and calibration records to
the USB interface automatically or manually.
Setting
The system menu or a sensor menu with submenus, settings and
functions is displayed
5.2.2 Navigation
Measured value display In the measured value display, you can
open the menu for calibration and measurement settings with <F1>
(short keystroke)
Open the Storage & config menu with the sensor-independent set-
tings with <F1__> (long keystroke, approx. 2 s).
Change the display in the measurement window by pressing
<MODE> (e.g. conductivity −> resistivity −> −> −> ).
Menus and dialogs The menus for settings and dialogs in procedures contain further sub-
elements. The selection is made with the <><>keys. The current
selection is displayed with a frame.
Submenus

Operation CO 3100 H
20 ba77074e05 05/2021
The name of the submenu is displayed at the upper edge of the
frame. Submenus are opened by confirming with <OK>. Example:
Settings
Settings are indicated by a colon. The current setting is displayed on
the right-hand side. The setting mode is opened with <OK>. Subse-
quently, the setting can be changed with <><>and <OK>.
Example:
Functions
Functions are designated by the name of the function. They are
immediately carried out by confirming with <OK>.
