Please keep the damaged goods until any issues have been resolved.
• Check the scope of delivery against the delivery papers and your order to ensure it is complete
and nothing is missing.
• Pack the device in such a way as to protect it reliably against impact and moisture for storage
and transportation. Optimum protection is provided by the original packaging materials. In
addition, the permitted ambient conditions must be observed (see Technical data).
• If you have any queries, please contact your supplier or local sales center.
1.3 Installation, commissioning and operation
Observe the following points:
• Installation, commissioning, operation and maintenance of the measuring system must only
be carried out by trained technical personnel.
The technical personnel must be authorized to perform the tasks by the owner-operator.
• The electrical connection may only be established by an electrical technician.

6.3.1 User roles and access authorization
If the password protection has been defined and activated, you have to log in with the
appropriate user role before you can make changes to the settings in the menu.
Here, you will be prompted by the device to enter an access code as soon as you want to
configure a value:
User roles and access authorization (factory setting):
! Note!
If you are logged in as the "Specialist" (=Administrator), you can change the access
authorization of all other user groups:
1. Select a submenu where you want to assign authorization to, or take authorization from,
another user group.
2. Press and hold down the navigator button for at least 3 seconds.
The display shows all the user groups and the current access authorization to the menu
selected.
3. Use the navigator to change the authorization in question and confirm with "OK".
4. Make a note of the changes in your operating logbook or similar.
6.4 Calibration
Calibration is necessary:
• At initial commissioning
• After replacing a sensor
Maintenance team Specialist Operator

• After periods of standstill
• At sensible, process-dependent intervals1).
6.4.1 Types of calibration
• Automatic buffer recognition (only pH):
– "PARAM"/"Sensor"/"Cal-settings"/"Buffer manufacturer" or
"PARAM"/"Quick Setup"/"Buffer manufacturer"
– You select the buffer type (e.g. DIN 19266).
– The device automatically recognizes the buffer during calibration.
• Fixed buffer (only pH):
– "PARAM"/"Sensor"/"Cal-settings"/"Buffer recognition"
– You select two buffer solutions from the menu.
• Manual:2)
– You enter the buffer values during calibration.
• Numeric input:
– "PARAM"/"Sensor"/"Cal-settings"/"Type of calibration"
– You enter the slope, zero point and temperature (for pH).
– You enter the mV value (for ORP).
6.4.2 Calibrate
Proceed as follows to calibrate the sensor:
1. Go through the menu "Param"/"Quick Setup" completely 3).
2. Remove the sensor from the process.
3. Clean the sensor.
4. Press the soft key for "CAL".
5. Follow the instructions in the menu.
6. Finish calibrating by switching back to the measuring mode.
7. Install the sensor back into the process.
Your measuring point is now ready for operation.
! Note!
• If calibration is aborted using ESC, or if the calibration is faulty, the system continues to use
the original calibration data. A calibration error is shown as plain text on the display.
• During each calibration, the device automatically switches to Hold (factory setting).
• Any offset set is automatically deleted after accepting the calibration.
1) Depending on the process conditions, the intervals can range from several times daily to once quarterly.
2) Not available during initial commissioning if you are working with the factory settings.
3) Only for initial commissioning
