Adjusting the measured value with the aid of wizards
In practice, the measurement typically needs to be adjusted based a reference value (e.g.
lab value) when commissioning the device to ensure optimum measurement performance
during subsequent operation. Repeating this adjustment is recommended if there are
significant changes to the process conditions or following replacement of the sensor
electronics module (ISEM).
The deviation from the value determined by the device can be checked and adjusted if
necessary with the aid of manually taken samples of the medium, which are analyzed in
the laboratory. The lab value is compared with the measured value of the device for this
purpose. The difference between the two values can then be used to decide whether the
measurement performance is sufficient or whether the device should be readjusted based
on the laboratory value.
The device has four wizards to facilitate this process. After starting each wizard, you are
guided through the necessary work steps.
Performing the basic settings for the adjustment:
1. Commissioning wizard
Adusting the measured value based on the reference value:
2. 1 - Take a sample wizard
3. 2 - Enter lab value wizard
4. 3 - Perform adjustment wizard
Adjustment can be carried out directly via local operation of the device or via the web
server.
The process using the wizards is essentially the same for both operation methods, but
more options and a graphic display are available when operating via the web server in
the 3 - Perform adjustment wizard. Using the web server is therefore recommended.
Online information
Further information on the procedure for performing an adjustment using wizards is also
available online.
11.8.1
Performing the basic settings for the adjustment
The Commissioning wizard is called up via the main menu: Setup → Total solids
adjustment → Commissioning
Commissioning
The Commissioning wizard is used to:
• set the system time (when using the wizard for the first time or after disconnecting the
device from the supply voltage)
• set the unit for the solids content for the measured total solids and the lab value
• enter the solids density
11.8.2
Adjusting the measured value based on the reference value
• All three wizards must be run each time the device is adjusted.
• You can call up the wizard options via the operating menu or during local operation
from the operational display by holding down the Enter key for longer than
3 seconds→ 132.
