DIL 402C Operating Instructions - Condensed Version - Starting a Measurement DIL 402 C DIL 402C Carrying Out a Measurement Explained below is how to: − set up a measurement, − create a correction curve, − and then to measure a sample. ! Detailed information " please see the hardware or software manual Step 1. Make sure that all system components are correctly connected. # Reference HARDWARE ! from Page 10 2. Switch on the thermostat at least two hours before starting the measurement. HARDWARE ! Page: 11 3. Switch on the measuring unit, TA Controller, power unit and computer at lease one hour before starting the measurement. ndr/rf/jh/I:\DIL402C\Kurzanleitungen\402CKU_E.DO C Page 2 DIL 402C Carrying Out a Measurement 4. Prepare the sample. HARDWARE ! Page: 40 5. Determine the sample length at room temperature. HARDWARE ! Page: 40 6. Loosen the retaining nut on the protective tube. 7. Slide the retaining nut and O-ring over the protective tube and leave them there. 8. Slide the furnace to the right to the limit stop. 9. If necessary, place sample supports in the sample holder. ndr/rf/jh/I:\DIL402C\Kurzanleitungen\402CKU_E.DO C Page 3 DIL 402C Carrying Out a Measurement 10. Place the standard sample (e.g. Al2O3 sample) on the sample supports. 11. Slide the pushrod over to the sample. Adjust the pushrod. 12. Position the thermocouple. The thermocouple must not come into contact with the sample. HARDWARE ! Page: 42 HARDWARE ! Page: 42 13. Slide the furnace carefully to the left to the limit stop. The sample holder must not come into contact with the protective tube. 14. Close the dilatometer with the retaining nut. ndr/rf/jh/I:\DIL402C\Kurzanleitungen\402CKU_E.DO C Page 4 DIL 402C Carrying Out a Measurement 15. Set the required atmosphere for the sample chamber.
