Note: Priming reagents can reduce
start-up time, see Section 3.2.1.

3.5 Supplying Power

Start sample flow through the instrument by opening the supply valve. Allow the
pressure in the tubing to stabilize and check for leaks.
Until the surface of the sample cell becomes completely wetted, bubbles may
cling to the sample cell and cause erratic readings. This condition is temporary. Its
duration depends on the dissolved oxygen content of the sample.
Set the POWER switch to ON and allow the monitor to operate for approximately
two hours to ensure the system is completely wetted with reagents and sample.
