- Page 53 5. HANDLING PRECAUTIONS Caution 11. Temperature control. The temperature sensor for this unit is installed on the inside wall of the chamber and used to control chamber temperature. Chamber temperature reading, as detected by the sensor, may not always agree with the temperature of test specimens. More often than not, chamber and test sample temperatures will differ largely immediately after opening or closing chamber door.
- Page 54 5. HANDLING PRECAUTIONS Caution 17. Cable port precaution. Whenever a manual temperature gauging sensor or probe is inserted through the cable port, close the port cover as fully as possible and completely seal any gaps with heat-resistant insulation or sealant. If the seal is inadequate, temperature characteristics or other performance properties will be degraded and inaccurate.
