Note

Do not use a square waveform for tuning. A square wave can cause the
extensometer to move or fall off the specimen, which can cause the
system to go unstable.

May yield sluggish response if P gain is set too low.

May yield unstable response is P gain is set too high.

Command sources

The program command source can come from an internal source (such as the
Function Generator or the MultiPurpose TestWare application) or from an
external device (such as an external profiler or function generator).

CLC control mode

Channel limited channel (CLC) control modes are used for specimen installation
and removal. Channel limited channels require two feedback signals.
