switch. Place the specimen between the two quartz lentils.
Then place the specimen and lentils between the low and high
pedestals. Pushing button 9 (Figure 2) lift the lower pedestal
until the upper lentil on the specimen contacts the higher
pedestal and shows a load of 1 N/cm2
under the Actual Load. Immediately release button (9), lower
the furnace and start the test by pressing any key on the
keyboard.

maximum value appears on the screen. This maximum value
is considered the restraining load of the particular specimen.

increasing press the enter button on the keyboard to stop the
test.
