The compact Lab 865 precision pH meter enables you to perform pH measure-
ments rapidly and reliably.
The Lab 865 provides the maximum degree of operating comfort, reliability and
measuring certainty for all applications.
The USB interface can be used for data transmission to a PC and for software
updates of the meter.
1.2 Sensors
A measuring system ready to measure consists of the Lab 865 meter and a
suitable sensor.
Suitable sensors are pH electrodes and ORP electrodes.

This operating manual provides important information on the safe operation of
the meter. Read this operating manual thoroughly and make yourself familiar
with the meter before putting it into operation or working with it. The operating
manual must be kept in the vicinity of the meter so you can always find the infor-
mation you need.
Important safety instructions are highlighted in this operating manual. They are
indicated by the warning symbol (triangle) in the left column. The signal word
(e.g. "CAUTION") indicates the level of danger:
NOTE
indicates a possibly dangerous situation where goods might be damaged
if the actions mentioned are not taken.
2.1.2 Safety signs on the meter
Note all labels, information signs and safety symbols on the meter and in the
battery compartment. A warning symbol (triangle) without text refers to safety
information in this operating manual.
2.1.3 Further documents providing safety information
The following documents provide additional information, which you should
observe for your safety when working with the measuring system:
• Operating manualsof sensors and other accessories
• Safety datasheets of calibration or maintenance accessories (such as buffer
solutions, electrolyte solutions, etc.)
WARNING
indicates a possibly dangerous situation that can lead to seri-
ous (irreversible) injury or death if the safety instruction is not
followed.
CAUTION
indicates a possibly dangerous situation that can lead to
slight (reversible) injury if the safety instruction is not fol-
lowed.

4.3 Switching off
Automatic switch-off
function
The instrument has an automatic switch-off function in order to save the
batteries (see section 7.3.1 SYSTEM, page 42). The automatic switchoff
switches off the measuring instrument if no key is pressed for an adjustable
period.

if the communication cable is connected
if the Automatic data storage function is active, or with automatic data trans-
mission
if the power pack is connected
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 section
7.3.1 SYSTEM, page 42).
4.4 Navigation
The principles of navigation in menus and dialogs are explained in the following
sections.

measurement settings for the displayed measured parameter.
Use <F1__>/[Menu] (long pressure (approx. 2 s) to open the Storage & con-
fig menu with the sensor-independent settings.
Use the keys of the keypad to carry out further functions such as storage or cali-
bration (see section 4.1.1 KEYPAD, page 12). These functions are not available
in other operating situations.

4.4.6 Example 2 on navigation: Setting the date and time
The measuring instrument has a clock with a date function. The date and time
are shown in the measured value display.
When storing measured values and calibrating, the current date and time are
automatically stored as well.
The correct setting of the date and time and date format is important for the fol-
lowing functions and displays:
Current date and time
Calibration date
Identification of stored measured values.
Therefore, check the time at regular intervals.

8. Select the required language with <><>.
9. Confirm the setting with <ENTER>.
The meter switches to the measuring mode.
The selected language is active.
After a fall of the supply voltage (empty batteries), the date and time
are reset.
