HandyLab 200 Safety
2 Safety
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 manual 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:
Further notes
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.
Note
indicates notes that draw your attention to special features.
Note
indicates cross-references to other documents, e.g. operating manuals.

Safety HandyLab 200
2.1 Authorized use
Authorized use of the meter consists exclusively of the measurement
of conductivity, resistivity, salinity, TDS (total dissolved solids) and temperature in a laboratory or field environment.
The technical specifications as given in chapter 7 T
ECHNICAL 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.
2.2 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 operation.
The smooth functioning and operational safety of the meter can only be
guaranteed under the environmental conditions that are specified in
chapter 7 T
ECHNICAL DATA.
If the meter was transported from a cold environment to a warm environment, 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 operation.
Caution
The meter is only allowed to be opened by authorized personnel.

ba77063e01 03/2014
HandyLab 200 Safety
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.

3 Place four batteries (type Mignon AA) in the battery compart-
ment.
4 Close the battery compartment.
Caution
Make sure that the poles of the batteries are positioned correctly.
The ± signs on the batteries must correspond to the
battery compartment.
Note
Alternatively, you can also use Ni-MH rechargeable batteries (type
Mignon AA). In order to charge the batteries, an external charging
device is required.
3.2.2 Switching on the meter

1 Press 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).
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 section 4.3.1).
