Using the Product
1. Assemble and warm up the probe following the steps in the previous sections
of this user manual.
2. Place the tip of the probe into the sample deep enough that the silver dot on
the shaft (thermistor for temperature compensation) is submerged, but not the
handle. The handle is not waterproof.
3. Gently stir the probe in the water. Monitor the dissolved oxygen concentration
in the live readouts.
It is important to keep moving the probe in the water sample. There must
always be water flowing past the probe tip while taking measurements due
to the consumption of oxygen at the membrane. If the probe is left still in
calm water, reported DO readings will drop erroneously.
If the water is not at room temperature, it is important to leave the probe in
the water long enough for the integrated thermistor, responsible for the
automatic temperature compensation, to have time to equilibrate; at least
two minutes.
