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).
