Ametek Chatillon CS1100 - Create a Compression Stage; Create a Hold Load Stage; Create a Hold Extension Stage

Also note that a "Cycle" action can consist of more than 2 Stages and can occur anywhere
within the test sequence, e.g.
1 Move up by 5 inches then move up another 2 inches then move back to the start of test
position. Repeat this action for 10 times.
2 Apply 20 lbf then cycle between 40 lbf and 50 lbf for 10 times.
9.6 CREATE A COMPRESSION STAGE
A "Compression" Stage is created in the same way as a "Tension" Stage, i.e. press on the
"COMPRESSION" button in the center of the screen to display the "LIMITS" screen.
9.7 CREATE A HOLD LOAD STAGE
A "Hold Load" Stage is used to maintain a "Constant Load" on the sample for a specified
time period and is commonly used to measure "Sample Creep" so is also called a CREEP
Test. The Force Tester is set to a special mode to move the crosshead as necessary to
maintain the specified load for the required time period.
Typical tests are foam tests, carton tests, paint can strength, seal strength (go/no go). The
test either checks that the sample can withstand the force for a time period or measures the
change in sample size over the time period.
Press on the "HOLD" button in the centre of the screen to display the "HOLD LIMITS"
screen.
Select "LOAD" to define a CREEP Test then enter the required HOLD duration.
9.8 CREATE A HOLD EXTENSION STAGE
A "Hold Extension" Stage is used to hold the Crosshead at a fixed position for a specified
time period and is also called a RELAXATION Test.
Typical tests are rubber door seals. The seal is held at a fixed distance between the door
and the frame and the test measures the change in seal force over the time period.
Press on the "HOLD" button in the centre of the screen to display the "HOLD LIMITS"
screen.
