PRECAUTIONS IN HANDLING
CAUTION
13. Do not place any samples on the bottom of the chamber
Do not place any samples on the bottom of the chamber to heat, because it affects the
temperature control of the oven. Always put the samples on the attached shelves.
Place sample so that it does not touch the interior wall of the chamber. Set the
shelves on the shelf brackets that will accommodate the size of the sample.
14. Never use corrosive samples
Stainless steel is used for major passage of circulating air. However, strong acid
occasionally corrodes even stainless steel. Besides this, the silicone rubber packing is
also vulnerable to acid, alkali, oil and halogen’s solvent.
15. When you open and shut the door
Do not put your hand either face near the door when you open and shut the door.
Failure to observe this caution may result in injury because the door hits your hand
or face.
16. When using the cable port
When you have inserted a measurement sensor or a probe into the cable port, close
the cover to the maximum extent possible and then securely seal it with
heat-resistant packing or sealant taking care not to leave any gaps. Insufficient seal
will degrade temperature characteristics or other performances.
