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 warning 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 manuals.

2.1Authorized use
This meter is authorized exclusively for pH and ORP measurements in a laboratory or field environment.
The technical specifications as given in chapter 7 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.
2.2General 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 The smooth functioning and operational safety of the meter can only be operational safety 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 7 TECHNICAL 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.

3Place four batteries (type Mignon AA) in the battery compartment.
4Close the battery compartment.
Caution
Make sure that the poles of the batteries are positioned correctly. The ± signs on the batteries must correspond to the ± signs in 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.
3.2.2Switching on the meter
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).
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).
