Priming the titrant tubes:

Place the filled titrant containers under the container cover, and under the
titrant tubes that are to be primed.

Attach a sample container, containing a small amount of clean water, to the dis-
persion head; this is used to catch the titrants during the priming process.
Water in the container is not essential, but will eliminate the effect of surface
tension at the end of the titrant tube.

Open the titrator application by selecting the Manual control icon.

Select the radio button for the titrant tube that is to be primed, or All to prime
all three titrant delivery tubes at once.

Select the cycles required and press the Prime button to begin the operation.
Each cycle will pump the volume of the titrant tubes from the container.
(Note that, once started, pressing
Prime a second time will stop the opera-
tion).

Priming will stop once the number of cycles has been completed.

When the prime operation has finished, titrant should be visible in the bottom
of the beaker. If none is dispensed, the
Prime button should be pressed again
to repeat the process.
Note
The titrant tubes can also be cleaned using the same tab. Simply insert con-
tainers of cleaning fluid in place of the titrant containers.
