5.5.2 Start measurement/measurement series
The ‚Start measurement series‘ menu is divided into three
areas ‚Measurement position / name‘, ‚Measuring range /
sample volume / ATH‘, and ‚Measuring duration / measuring
interval‘. You can switch between the three areas with the up
▲
and down
▼
arrow keys.
If the A-symbol at the top left of the menu is grey, it means
that Autostart mode is deactivated (Figure 6); otherwise it
is activated. It can be switched on and off in the ‚Options‘
submenu (see 5.6 Options, 5.6.1 Autostart).
Measurement position / name:
One of the six measure-
ment positions can be selected with the left
►
and right
►
arrow keys or the head keys. The number keys one to six
have the same function as the head keys in this menu.
If a head is recognised at the selected measurement position, the measurement parameters and head
name are displayed. The LED in the head illuminates continuously.
If you use the arrow keys to switch to the next, measurement positions without heads are skipped.
The displayed measurement parameters and the head name are saved in the head. The parameters
of the current and/or last measurement from the selected head are always displayed. The head name
can be changed in the ‚Options‘ menu.
Select the measurement location with the prepared sample.
Measuring range / sample volume / ATH:
You adjust the measuring range here. The sample volu-
me required for the measuring range and the quantity of nitrification inhibitor are displayed.
Measuring duration / measuring interval:
Specify the measuring duration here.
A measurement is performed with the selected sensor every hour during the first 24 hours, every two
hours during the next 24 hours, and once every 24 hours thereafter.
Start the series of measurements with function key F2 (start). The previous measurement results and
parameters in the selected head are overwritten in the process.
A corresponding warning message always appears.
Press function key F1 (back) to return to the main menu.
