sample sizes of approx. 10 g, which is our recommendation as a good sample
weight.

) "PFl" is the "PreFlash" feature, which is useful for very wet samples to shorten the
measuring time. This parameter is set to a certain value for the remaining dry
substance. E.g. a material has moisture of 90 % and dry material of 10 %, the
parameter should be set to 30 %. Then the radiator will start to dry with full energy
(100 %) and when the value of 30 % dry substance is reached, it will dry to the
automatic stop with a lower energy set by the parameter "Heat". Results has to be
set to "dM" in that case. Users in waste water plants often use this feature.
5. Drying temperature
The drying temperature can be set by adjusting the menu item "Heat" to an exact
value of % energy. This means % of 230 Volt power. Of course there is a certain
connection between the power and the temperature.

Please take into consideration, that the sample temperature is depending very much
on the quality and mostly on the colour of the sample. A light sample will get much
less hot than a dark sample. Therefore the temperatures are only approximate.
The radiator's power can be changed also during a measurement. Press the „Tara"
button and the „Set" button at the same time. Use the turn switch to set the power in
%. The value is shown in the display.
(For UX 2031 models only)
Only the bright radiator is adjustable, the quartz radiator dries only with 100 % power.
