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 meter or
the environment.

2.1 Authorized 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.
2.2 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 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.

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.
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.
3.2.2 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
section 4.3.1).
3.2.3 Setting the date and time
4Close the battery compartment (2) and tighten the screws (1).
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).
