Insert the adapter for 13 mm Ø round vials.
Place the blank in the sample chamber and perform zero calibration
(see “Operation”). The blank is part of the test kit.
Water should flow through the special sample container for several
minutes to remove any air bubbles sticking at the surface.
The water must flow from the bottom to the top.
When the sample container is bubble-free press one Vacu-vial
®
into
the lower edge of the sample container. The Vacu-vial
®
breaks at the
neck and the vial fills automatically.
A small volume of inert gas remains in the Vacu-vial
®
.
Remove the Vacu-vial
®
point downwards from the sample container
immediately.
As the contents of the vial has a higher density than water, it is impor-
tant to remove the vial from the sample container within 5 seconds to
prevent any loss of reagent.
Invert the vial several times. Dry the outside of the vial.
Place the Vacu-vial
®
in the sample chamber.
Press the [ZERO/TEST] key.
The method symbol flashes for approx. 3 seconds.
