Precautions in handling
CAUTION
Caution about the temperature range.
・
Use the oven in the range of 40
℃
to 210
℃
When you use the oven for the first time
・
During the initial operation, the oven may occasionally generate an odor especially when
high temperatures are resched. This odor is nomal and does not signal a problem with the
oven. The nature of the odor is caused by the adhesive on the insulation melting
About the temperature in the chamber
・
Temperature display indicates the sensor temperature installed in the unit, however it
does not always correspond to the tempwrature of the sample when the sample volume is
very large or when the temperature is on the increase.
Caution about a drenched sample
・
When using a very wet sample, try to drain it as much as possible before putting it in
chamber.
Caution about powdery sample and the loading of samples
・
There are times when a powder sample is scattered by the sudden decompressin
operation or purge operation. When performing decompression or purge,open the valve
very slowly.
・
It occasionally takes a long time before the chamber reaches the target temperature if
the chamber is congested with samples with the large specific heat is in it.
In such cases, reduce samples. Moreover, note that the temperature display
occasionally unsettle when you process a exothermic sample.
Distribute samples
・
Each shelf can carry a uniform load of 15 kg(33 lb.). When you place samples on a shelf,
distribute them evenly over the shelf area.
・
If a shelf is congested with samples, the oven occasionally cannot regulate temperatures
properly. To ensure the oven’s temperature accuracy, there should be open space of at
least 30% on each shelf.
