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 operators will know the necessary safety precautions to take when handling chemicals.

ECHNICAL

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 Operation

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.
