If the reagent was dispersed involuntary in the whole reactor, it is also recommended to clean
the reactor. If the powder is only below the reagent tray in some quantities, just pull out the

top and let the powder fall out.
After the cleaning a dry run should be performed.

Dry Run
A dry run is necessary:
Before first use,
after the reactor has been left open for a longer period
or
if the water content of a previous measurement exceeded 50 mg
Although very low water contents are to be measured and the device was not in use before,
a dry run is recommended. If the HydroTracer is not in use the unit must always be kept closed
and be filled with reagent
A dry run is carried out in accordance with section “2 Performing a Test”
,
with the difference:
no sample material is used
the heating temperature is set to 210 °C
for the sample weight is enter 1 g and for the density 1g/cm³
