1Safety
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 man-
ual 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 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 warn-
ing 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

1.1 Authorized use
This meter is authorized exclusively for pH and ORP measurements in
a laboratory environment.
The technical specifications as given in chapter 3 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.
1.2 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 opera-
tion.
The smooth functioning and operational safety of the meter can only be
guaranteed under the environmental conditions that are specified in
chapter 3 TECHNICAL DATA.
If the meter was transported from a cold environment to a warm envi-
ronment, 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 opera-
tion.
Caution
The meter is only allowed to be opened by authorized personnel.

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.
4.2.2 Connecting the power pack
Caution
The line voltage at the operating site must lie within the input volt-
age range of the original power pack (see section 3.1).
Caution
Use original power packs only.
Note
You can carry out measurements without the power pack.
4.2.3 Switching on the meter
1Open the battery compartment (1) on the underside of the
meter.
2Place four batteries (type Mignon AA) in the battery compart-
ment.
3 Close the battery compartment.
1Insert the plug into the socket of the pH 1100 L.
2 Connect the original power pack to an easily accessible power
outlet.
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 sec-
tion 5.3.1).

5.1 Switching on the meter
Switching on Press the <On/Off> key.
The meter performs a self-test.
The display shows the manufacturer's logo while the self-test is being
performed.
The measured value display appears.
Switching off Press the <On/Off> key.
Automatic switch-off
function
The instrument has an automatic switch-off function in order to save the

es off the meter if no key is pressed for an adjustable period.
The automatic switch-off function is not active
if the communication cable is connected
if the power pack is connected
if the Autom. storage function is active, or with automatic data trans-
mission
Display illumination The meter automatically switches off the display illumination if no key
is pressed for 30 seconds. The illumination is switched on with the next
keystroke again.
You can also generally switch the display illumination on or off (see

Measured value display In the measured value display, you can
open the menu for calibration and measurement settings with <F1>
(short keystroke)
open the system menu with the sensor-independent settings by
pressing <F1>Storage & config for a <F1__>long keystroke,
approx. 2 s).
change the display in the selected measuring screen (e. g. pH <->
mV) by pressing <MODE>.
Menus and dialogs The menus for settings and dialogs in procedures contain further sub-
elements. The selection is made with the <><>keys. The current
selection is displayed with a frame.
Submenus
The name of the submenu is displayed at the upper edge of the
frame. Submenus are opened by confirming with <OK>. Example:
