Multi 3320 Overview
ba77053e04 07/2018 7
1 Overview
1.1 Multi 3320 meter
The Multi 3320 meter enables you to perform measurements (pH, U, ISE, con-
ductivity, dissolved oxygen) ) quickly and reliably.
The Multi 3320 provides the maximum degree of operating comfort, reliability
and measuring certainty for all applications.
1.2 Sensors
A measuring system ready to measure consists of the Multi 3320 meter and a
suitable sensor.
1 Keypad
2 Display
3 Connectors

Suitable sensors are pH electrodes, ion selective electrodes (ISE), ORP elec-
trodes, dissolved oxygen (D.O.) sensors and conductivity measuring cells.
Suitable sensors are pH electrodes, ion selective electrodes (ISE) and ORP
electrodes.
Information on available sensors is given on the Internet and in the
WTW catalog, "Laboratory and field instrumentation".

2 Safety
2.1 Safety information
2.1.1 Safety information in the operating manual
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 manuals of 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.

2.2 Safe operation
2.2.1 Authorized use
Only the operation and running of the meter according to the instructions and
technical specifications given in this operating manual is authorized (see
section 15 TECHNICAL DATA, page 92).
Any other use is considered unauthorized.
2.2.2 Requirements for safe operation
Note the following points for safe operation:
• The meter may only be operated according to the authorized use specified
above.
• The meter may only be supplied with power by the energy sources
mentioned in this operating manual.
• The meter may only be operated under the environmental conditions
mentioned in this operating manual.
• The meter may only be opened if this is explicitly described in this operating
manual (example: Inserting the batteries).
2.2.3 Unauthorized use
The meter must not be put into operation if:
• it is visibly damaged (e.g. after being transported)
• it was stored under adverse conditions for a lengthy period of time (storing
conditions, see section 15 TECHNICAL DATA, page 92).
This meter is authorized exclusively for pH, ISE, ORP, dissolved oxygen and
conductivity measurements in a field and laboratory environment.
This meter is authorized exclusively for pH, ISE and ORP measurements in a
field and laboratory environment.

4.4.6 Example 2 on navigation: Setting the date and time
The meter 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.
7. Open the setting mode for the Language with <ENTER>.
