TA Instruments DMA 850 - Installing the ACS Clamp Screen; Clamp Screen Usage and Temperature Limit

Installing the ACS Clamp Screen
NOTE: It is important to use the included ACS Clamp Screen found in the kit when using either the ACS-
2 or ACS-3. The screen helps maintain a uniform temperature around the sample and thermocouple, allow-
ing for more accurate temperature readings of the sample.

Bending.
After mounting the sample, slide the appropriate ACS Clamp Screen over the clamp.

WARNING: The metal band on the ACS Clamp Screen is made of aluminum. The upper tempera-
ture of the DMA 850 with ACS is limited to 400°C, and the Instrument Control Software will not
allow a temperature higher than 400°C when the ACS is the chosen accessory. It is vitally
important not to request a temperature higher than 400°C at any time when the ACS Clamp
Screen is installed. Major damage to the DMA 850 can occur if the furnace is commanded to go
above 400°C when an ACS Clamp Screen is installed.
AVERTISSEMENT: L'échangeur de chaleur de l'ACS est en aluminium. La température maximale
du DMA 850 avec l'ACS est donc limitée à 400 ° C et le logiciel de contrôle d'instruments n'auto-
rise pas une température supérieure à 400 ° C lorsque l'ACS est l'accessoire choisi. Il est
extrêmement important de ne pas demander une température supérieure à 400 ° C à tout
moment lorsque l'ACS est installé . Des dommages importants au DMA 850 peuvent se produire
si le four est programmé pour aller au-dessus de 400 ° C quand un ACS est installé.
