1.1 General features
The ProLab 2000 precision meter enables you to perform pH, ORP,
conductivity, dissolved oxygen (D.O.) and ion-selective measurements
rapidly and reliably.
The ProLab 2000 provides the maximum degree of ease of use,
reliability and, above all, measuring certainty for all applications.
The proven calibration procedures, and stability control function (SC)
and the sensor recognition function support your work with the meter.
In addition, the ProLab 2000 provides an electronic access control.
Documented measurement data is thus automatically assigned to a
user.

1.5 Automatic sensor recognition
The automatic sensor recognition function enables
to operate a sensor with different meters without recalibrating
to operate different sensors with one meter without recalibrating
to assign measurement data to a sensor
– measurement datasets are always downloaded to the interface
with the sensor type and sensor series number.
– measurement datasets are always stored together with the
sensor type and sensor series number.
to assign calibration data to a sensor
– calibration data is always downloaded to the interface with the
sensor type and sensor series number.
the automatic activation of the cell constants for conductivity
sensors
To be able to use the automatic sensor recognition function a meter is
required that supports the automatic sensor recognition (e.g.
ProLab 2000), and a sensor (ID sensor) that is suitable for sensor
recognition.
In every ID sensor, sensor data is stored that clearly identifies the
sensor.
The sensor data is sent to the meter automatically via radio
communication and used for sensor identification there.
Note
With the ProLab 2000 meter, you can also operate non-ID sensors.
Then, however, you cannot use the advantages of the sensor
recognition function.

ID sensor symbol
ID sensors SI Analytics ID sensors support the automatic sensor recognition
function. Their sensor designation has the addition "ID", e.g.
A 161 1M DIN-ID electrode.
Note
Information on available ID sensors is given on the Internet or directly
by SI Analytics.
ID sensors connected to the ProLab 2000 meter can be recognized by
the ID sensor symbol on the display of the meter.
Sensor data from ID
sensors
ID sensors transmit the following sensor data to the meter:
SENSOR ID
– Sensor type
– Sensor series number
Calibration data
– Calibration date
– Calibration characteristics
– Calibration interval
– Selected buffer set (pH electrodes only)
The calibration data is updated in the ID sensor after each calibration
procedure. The ID sensor symbol flashes while this is done.
Note
While the ID sensor symbol is flashing, the sensor must not be
disconnected because otherwise the calibration data will not be
completely transmitted. The sensor will then have no valid calibration.
Note
If non-ID sensors are used, the calibration data from the meter is used
and also stored in the meter.

access control
1.6 Electronic access control
The ProLab 2000 always documents measurement data and
calibration data with an ID number (USER ID).
If the USER ID is assigned to a certain user, all measurement data is
also assigned to the user in compliance with GLP.
The USER ID is easily and safely transmitted to the ProLab 2000 via
an electronic key. Each electronic key in the form of a keyring pendant
contains a key number. The key number is read by the meter via a
contactless radio data connection and used as the USER ID.
The meter checks the access authorization for the USER ID.
Measurements with an electronic key are only possible if the USER ID
is registered in the meter.
The measuring data is then documented along with the registered
USER ID.
ba75577e05 11/2013
If the USER ID of the electronic key is not registered in the meter,
access to the meter with this electronic key is denied.
Anonymous access is always possible. For anonymous access, the
USER ID 0 is used automatically.
By labeling measurement data without electronic key with USER ID 0,
this data can be separated from the GLP-compliant documentation of
measurements.

ProLab 2000 Safety
2 Safety
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
manual before working with the measuring system. 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 The individual chapters of this operating manual use the following
safety instruction to indicate various types of danger:
CAUTION
indicates instructions that must be followed precisely in order to
avoid the possibility of slight injuries or damage to the meter or
the environment.
Further notes
Note
indicates notes that draw your attention to special features.
Note
indicates cross-references to other documents, e.g. operating
manuals.
2.1 Authorized use
This meter is authorized exclusively for measurements of the pH, ORP,
conductivity, D.O. and ion-selective measurements in the laboratory.
The technical specifications as given in chapter 7 T
(page 105) 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.

Safety ProLab 2000
2.2 General safety instructions
This instrument is built and inspected according to the relevant
guidelines and norms for electronic measuring instruments (see
page 105).
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
operation.
The smooth functioning and operational safety of the meter can only be
guaranteed under the environmental conditions that are specified in
chapter 7 T
ECHNICAL DATA (page 105).
If the meter was transported from a cold environment to a warm
environment, 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
operation.
Safe operation If safe operation is no longer possible, the meter must be taken out of
service and secured against inadvertent operation!
Safe operation is no longer possible if the meter:
has been damaged in transport
has been stored under adverse conditions for a lengthy period of
time

4.2.4 Navigation example 2: Setting the date and time
The meter has a clock with a date function. The date and time are
indicated in the status line of the measured value display. This
indication can be switched off. When storing measured values and
calibrating, the current date and time are automatically stored as well.
The correct setting of the date, time and date format is important for the
following functions and displays:
Current date and time
Calibration date
Identification of stored measured values.
Therefore, check the time at regular intervals.
Note
After a drop of the voltage of the buffer batteries (empty batteries), the
date and time are reset and have to be adjusted again.
Setting the date, time
