5.2 Measuring
Preparatory activities Perform the following preparatory activities when you want to measure:
Stability control
[Auto]
During the measuring procedure, the stability control function is automatically activated. The stability control function [Auto] checks the stability of the measured oxygen signal and the stability of the measured
temperature signal. The stability has a considerable effect on the reproducibility of the measured value.
The status display [Auto] flashes until a stable measured value is available. As soon as the measured value is stable the status display [Auto]
stops flashing.
For identical measurement conditions, the following applies:
Temperature sensor The temperature measurement is absolutely essential for a reproduc-
ible oxygen measurement. If a temperature sensor is integrated in the
sensor, it is indicated on the display by [TP].

Note
The OX 4000 H D.O. meter automatically recognizes the type of connected D.O. sensor (OXY 11).
Temperature sensor The D.O. sensor has an integrated temperature sensor that always
measures the current temperature of the test sample.
Warning
When connecting an earthed PC/printer, measurements cannot be performed in earthed media as incorrect values would result. The RS232
interface is not galvanically isolated.
5.2.3 Measuring the D.O. concentration
Note
When measuring the concentration of test samples with a salt content
of more than 1 g/l, a salinity correction is required. For this, you have to
measure and input the salinity of the test sample first. This is described
in section 5.2.7 E
NTERING THE SALT CONTENT (SALINITY).
Switch on the salinity correction prior to measuring the D.O. content
(see below).
You can measure the D.O. content without salinity correction as follows:
Stability control The stability control function continuously checks the stability of the
measurement signal. The stability has a considerable impact on the
reproducibility of measured values. The [Auto] display flashes until a
stable measured value is available.
1 Perform the preparatory activities according to section 5.2.2.
2 Immerse the D. O. sensor in the test sample.

5.2.5 D.O. calibration
Why calibrate? D.O. sensors age. This changes the slope of the D.O. sensor. Calibra-
tion determines the current slope of the sensor and stores this value in
the instrument.
When to calibrate? After connecting another D.O. sensor
When the sensor symbol flashes (after the calibration interval has
expired).
Calibration procedure Calibration in water vapor-saturated air.
Use an air calibration vessel for calibration.
Note
The OXY 11 sensor is zero-current free
(see operating manual
OXY 11). Therefore the calibration of the zero point is not necessary
and even not provided.
Stability control
[Auto]
In calibration, the stability control [Auto] function is automatically activated.
Displaying the
calibration data
You can have the data of the last calibration displayed (see section
5.2.6).
Calibration evaluation After the calibration, the meter automatically evaluates the current sta-
tus of the calibration. The evaluation appears on the display and in the
calibration record.

5.4 Transmitting data
The meter has a USB-B interface (device).
Via this interface you can transmit data to a PC and update the meter
software.
Note
The interface cable has to be connected if you want to download data
to the USB interface.
In addition, the driver for the USB interface must be installed on the PC
from the enclosed CD-ROM (see section 5.4.4).
Terminal program Generally, a terminal program is used to establish a connection to an
instrument at a data interface and to communicate with this connection
via a console on the display. A terminal program normally enables you
to store in a text file or print out the contents of the console.
Terminal programs are available from different manufacturers for different operating systems. Windows (versions 95 to XP) includes the terminal program, "HyperTerminal". It is under accessories in the program
menu.
More detailed information is given in the user information of the terminal program.
Caution
The interface is not galvanically isolated.
When a grounded PC is connected, measurements cannot be performed in grounded media as incorrect values would result.
