Repeat Count - Thermo Scientific gibco CTS Rotea User Manual

A loop is a selection of steps within a protocol that repeat. Each loop has a Do Steps While condition
that the software checks prior to performing the loop. If the condition is true, the loop runs. If it is false,
the protocol skips the loop and advances to the first step directly after the loop.
For example, a user wants the loop to continue until the Bubble Sensor on line B is triggered. The
Bubble Sensor B Not Triggered condition is selected from the dropdown, making the condition Do
Steps While Bubble Sensor B Not Triggered.
When the protocol reaches the loop for the first time, the software checks whether Bubble Sensor B
has been triggered. Since it has not, the condition is true, and the loop runs.
Each time the loop reaches the end, it jumps back to the start and checks the condition again. If Bubble
Sensor B is triggered at any point during a loop, the next time the loop condition is checked, the
condition will be false, and the protocol will not perform the loop.

Repeat Count

A Repeat Count condition causes the loop to repeat until it has repeated the number of times entered
in the value box.
Note: Once the loop condition is met, the Repeat Count resets to zero.
