1.1 General features

The ProLab 1000 precision pH meter enables you to perform pH, ORP and ion-selective measurements rapidly and reliably. The ProLab 1000 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 1000 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.

To be able to use the automatic sensor recognition function a meter is required that supports the automatic sensor recognition (e.g. ProLab 1000), 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 1000 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 1000 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.

ba75576e05 11/2013

ProLab 1000 Overview

Reader unit for access control

1.6 Electronic access control

The ProLab 1000 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 1000 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.

ba75576e05 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 1000 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 pH, ORP and ion-selective measurements in the laboratory. The technical specifications as given in chapter 7 T (page 83) 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.

2.2 General safety instructions

This instrument is built and inspected according to the relevant guidelines and norms for electronic measuring instruments (see page 83). 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 83).

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

Obligations of the

purchaser

 is visibly damaged

 no longer operates as described in this manual.

If you are in any doubt, please contact the supplier of the meter.

The purchaser of this meter must ensure that the following laws and guidelines are observed when using dangerous substances:

 EEC directives for protective labor legislation

 National protective labor legislation

 Safety regulations

 Safety datasheets of the chemical manufacturers.

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.
