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 sen-
sor 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 sen-
sors
to hide menus that are not relevant for this sensor
To be able to use the automatic sensor recognition function a meter is
required that supports the automatic sensor recognition (e.g.
ProLab 4000), 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.
16
Note
With the ProLab 4000 you can also operate non ID sensors. Then,
however, you cannot use the advantages of the sensor recognition
function.

1.5.1 ID sensors
SI Analytics GmbH ID sensors support the automatic sensor recognition function. Their sensor designation has the addition "ID", e.g. BlueLine A 161 1M-BNC-ID electrode.
Note
Information on available ID sensors is given on the Internet or directly
by SI Analytics.
ID sensors connected to the ProLab 4000 meter can be recognized by
the ID sensor symbol on the display.
ba75646e03 12/2012

Overview ProLab 4000
1.5.2 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
– User (having carried out the last calibration procedure)
– Calibration characteristics
– Calibration interval
– Selected buffer set (pH electrodes only)
– Last cell constant (conductivity measuring cell only)
Measurement settings (conductivity measuring cells only)
– Specified reference temperature
– Adjusted temperature coefficient
– Adjusted TDS factor
The calibration data is updated in the ID sensor after each calibration
procedure. A message is displayed while data is updated in the sensor.
Note
While data is updated in the sensor, 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.

key
1.6 Electronic access control
The ProLab 4000 always documents measurement and calibration
data together with a user name.
Thus all measurement data is assigned to the user, in compliance with
GLP.
The user name is easily and safely transmitted to the ProLab 4000 via
an electronic key. Each electronic key in the form of a keyring pendant
contains a key number and a user name. The key number and user
name are read by the meter via a contactless radio data connection.
The meter checks the access authorization for the user name. Measurements with an electronic key are only possible if the key number
and user name is registered in the meter. The measuring data is then
documented along with the registered user name.
ba75646e03 12/2012
If the user name of an electronic key is not registered in the meter,
access to the meter with this electronic key is denied.
If access to the meter is anonymous (no password, no electronic key
required), all data are documented with the user name, Anonymous.
By labeling the measurement data with Anonymous, this data can be
excluded from the GLP-compliant documentation.
