1. Safety
This Operating Instructions Manual contains fundamental information that should be observed in connection with the
installation, start-up, operation and maintenance of the instrument in connection with the sensor. Therefore, it is absolutely
vital for the user to read this manual prior to workin g with it.
User qualification
The meter has been designed for analytical measurements. It is assumed that the user/operator and the maintenance
personnel have the proper professional skills and experience to know the specific properties of analytical measuring
systems, master the safe handling of chemicals, for example, in the maintenance of electrodes/sensors, and can assess
any dangers and risks resulting thereof. The user must ensure that the national legislation and procedures concerning the
maintenance of industrial health and safety standards, the accident preventions and the handling of chemicals are
observed.
Installation and getting started
The perfect functioning and operational safety of the instrument can only be maintained under the climatic conditions
specified in the section "Specification" of this manual. When the instrument is moved from cold to warm surroundings,
condensate may occur and interfere with the functioning of the instrument. In such case, the user should wait until the
temperature of the instrument has adapted to t he ambient temperature b efore using the instru ment again.
Use the sensor and interface cables recommended by the manufacturer only. For the sensors and accessories, the
instructions and regulations given in the respective operating instructions manuals and specification sheets will apply. The
instrument can only be operated with the battery specified in the section “ Specification”.
Be careful when connecting other instruments (e.g. via interface). Connections with external instruments may cause not
permissible potentials inside the instrument (e.g. connections between GND and earth). These potentials may result in
operational influences or malf unctions in the instrum ent itself or the ext ernal devices conne cted.
Proper usage
The meter and the sensor are intended for measuring and docu mentation of analy sis parameters. T aking into consideration
the “Specification” paragraph, operating and using the unit for this application is the proper usage. Any application beyond
this and individual modifications or extensions are improper and will lead to loss of entitlement to the warranty. When
connecting the unit with electrochemical sensors, always take into account their life and natural wear as this may result in
malfunctioning of the measuring system and the regulation or control associated therewith. The user must take suitable
measures to limit harmful effects of such malfunctioning.
General safety instructions
The complete meter has been manufactured and tested in accordance with the relevant guidelines and standards for
electronic measuring equipment. It has left the fact ory in technically unobj ectionable condition.
The perfect functioning and operational safety of the instrument and the accompanying components will only be ensured if
the user observes the normal safety precautions as well as the specific safety guidelines stated in the present manual and
in the relevant operating instruction manuals of the components. If there is reason to assume that the instrument can no
longer be employed without a risk, it must be set aside a nd appropriately marked to prevent further use.
The safety of the user may be endangered, e.g. if the instrument or one of its components
•
shows visible damage,
•
no longer operates as specified,
•
has been stored over a longer period under unsuitable conditions,
•
has been subjected to difficult conditions during transport.
If in doubt, please contact your supplier and sent back t he instrument to the manuf acturer for repair and maintenance.

2. Sockets
2 sockets for connecting the sensor and the” Interface HMG USB” are located on the front side of the instrument. Please
use only the delivered original cable for the interface with the PC. For protecting the sockets against moisture and to avoid
corrosion, the sensor should always b e con nected to the i nstrument and the “Interface HMG USB” so cket shoul d be seale d
by means of the protection cap if it is not in use. The “Interface HMG USB” is not included in the deliv ery.
Cable Sockets
2.1 Battery
Please open the battery chamber on the back sid e of the instrument an d insert the battery correctly into the cham ber.
Battery Chamber
Please use batteries from the type AA, IEC R6, LR6 only. After connecting and inserting the battery, please close the
battery chamber carefully an d correctly, to avoid moistu re coming inside t he device.
If the battery is in low condition, the device shows these with only 1 bar in battery indicator display. A change of the battery
is recommended. If there is no bar in the display, t he battery must be cha nged immediately.
Only for AM 40:
After changing battery or sensor please note the wait time before a new calibration. We recommend a new
calibration after battery change, because the permanent polarisation of the sensor was interrupted by
disconnecting the sensor from the battery.

By pressing the button “ON/OFF“ the meter switches on. The meter switches off either automatically after a
preset time-out or by long (approximately 3 seconds) pressing th e “ON/OFF“ button.
Only for AM 40:
Also when the AM 40 is switched off, the connected O2-Sensor is supplied with the necessary polarisation
voltage and so the system is directly after switching on always ready to measure.
