_
DANGER
This symbol warns of imminent danger, which can result in death, severe bodily injury,
or severe property damage in case of non-observance.
_
CAUTION
This symbol warns of potential dangers or harmful situations, which can cause damage
to the device or to the environment in case of non-observance.
_
NOTE
This symbol indicates processes, which can have a direct influence on operation or
can trigger an unforeseen reaction in case of non-observance.
2.2 Foreseeable misuse
_
The fault-free function and operational safety of the device can only be guaranteed if
applicable safety precautions and the device-specific safety instructions for this
document are observed.
If these notices are disregarded, personal injury or death, as well as property damage
can occur.
_
DANGER
Incorrect area of application!
In order to prevent erratic behaviour of the device, personal injury or property damage,
the device must be used exclusively as described under intended use.
–Do not use in safety / Emergency Stop devices!
–The device is not suitable for use in explosion-prone areas!

2.3 Safety instructions
_
CAUTION
Measuring cell must never come into contact with water-repellent materials such as oil
or silicone.
CAUTION
Empty batteries and batteries of inferior quality can leak more easily, which can
destroy the device. Please also observe the instructions in the chapter “Operation and
maintenance”.
NOTE
This device does not belong in children's hands!
2.4 Intended use
_
The device is designed for measuring the conductivity in liquids.
The measuring cell is connected permanently.
The range of application depends on the different measuring cells of the type:
G 1409
2-pole titanium measuring cell, with a wide range of applications
e.g. fish farming, hydroponics, measurement of surface water and
drinking water.
G 1410
2-pole graphite measuring cell, with a wide range of applications
e.g. fish husbandry, measurement of surface water and drinking
water
G 1420
2-pole stainless steel measuring cell for low conductivities <100μS
e.g. pure and purest water, boiler water, osmosis and filter
technology
2.5 Qualified personnel
For commissioning, operation and maintenance, the relevant personnel must have
adequate knowledge of the measuring process and the significance of the
measurements. The instructions in this document must be understood, observed and
followed.
In order to avoid any risks arising from interpretation of the measurements in the
concrete application, the user must have additional expertise. The user is solely liable
for damages/danger resulting from misinterpretation due to inadequate expertise.
