This option gives an on-screen visual guide through a number of standard maintenance procedures
to perform on the instrument.
Installation
The installation wizard will be invoked automatically the first time the instrument is switched on to help you
complete the installation of the instrument.
Once the instrument has been successfully installed, the
Skip installation wizard on device startup checkbox
should be checked to ensure a normal startup from there onwards.
Maintenance
It is recommended to use the maintenance wizards for maintenance of the instrument. Simply follow the on-
screen instructions available for each of the options.
Antifoam tank filling
When refilling the cartridge, follow the instructions given in
on page 20.
To ensure the performance and reliability of the instrument, it is strongly
recommended to only use the silicone antifoam supplied by Hach Lange (part
number 33156).
EC sensor maintenance
Chemical reactions within the gas sensor requires that the oxygen sensor be
serviced regularly to restore its original sensitivity. A clear sign that a sensor
maintenance is required is when measurements are noticeably less stable than
usual.
For EC sensor maintenance, please also refer to the instruction sheet entitled
A1100 cleaning procedure for 6110 TPA
which is supplied with the instrument.
