The instrument warranty covers manufacturing faults that are discovered within the warranty period. The warranty does not cover components that are replaced during maintenance work, e.g. batteries.
The warranty claim extends to restoring the instrument to readiness for
use but not, however, to any further claim for damages. Improper handling or unauthorized opening of the instrument invalidates any warranty claim.

2Safety
This operating manual contains basic instructions that you must follow during
the commissioning, operation and maintenance of the pH meter. Consequently, all responsible personnel must read this operating manual before
working with the measuring system. The operating manual must always be
available within the vicinity of the measuring system.
Target group The measuring instrument was developed for work in the field and in the lab-
oratory.
We assume that, as a result of their professional training and experience, the

Note
indicates notes that draw your attention to special features.
Note
indicates cross-references to other documents, e.g. operating manuals.
2.1 Authorized use
The authorized use of the measuring instrument consists exclusively of the
pH and ORP measurement in the field and laboratory.
The technical specifications as given in section 1.4 T
observed. Only the operation and running of the measuring instrument according to the instructions given in this operating manual is authorized.
Any other use is considered to be unauthorized.

Function and oper-
ating safety
The smooth functioning and operational safety of the measuring instrument
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 measuring instrument
can only be guaranteed under the environmental conditions that are specified
in section 1.4 T
ECHNICAL DATA.
If the instrument was transported from a cold environment to a warm environment, the formation of condensate can lead to the faulty functioning of the instrument. In this event, wait until the temperature of the instrument reaches
room temperature before putting the instrument back into operation.
Safe operation If safe operation is no longer possible, the instrument must be taken out of
service and secured against inadvertent operation!
Safe operation is no longer possible if the measuring instrument:
z has been damaged in transport
z has been stored under adverse conditions for a lengthy period of time
z is visibly damaged
Obligations of the
purchaser
z no longer operates as described in this manual.
If you are in any doubt, please contact the supplier of the instrument.
The purchaser of the measuring instrument must ensure that the following
laws and guidelines are observed when using dangerous substances:
z EEC directives for protective labor legislation
z National protective labor legislation
z Safety regulations
z Safety datasheets of the chemical manufacturers.

4.1 Switching on the measuring instrument
1 Press the <ON/OFF> key.
The display test appears briefly on the display.
Subsequently, the slope and asymmetry used appear for approx. one second one after the other. In addition, the calibration
procedure of the last calibration is shown (AutoCal TEC or
AutoCal DIN or no display in the delivery state or following initialization).
The measuring instrument then automatically switches to the
measuring mode that was last selected.
Note
The measuring instrument has an energy saving feature to avoid unnecessary battery depletion. The energy saving feature switches the measuring instrument off if no key has been pressed for an hour. The energy saving
feature is not active when the AutoStore function is active.
