Health check ITMX 250522
I performed the health check ITMX.

Most part seemed healthy, we need larger amplitude for P measurement?

I increased the excitation count for P measurement, but the situation didn't change.

Since suspension would be just released and close to touch somewhere, I tuned the diaggui template for the measurement of pitch TF to reduce the RMS of suspension motion during the TF measurement.
What I did is to add notches at resonances and tuned overall excitation amlitude of the template.
Final setting is shown in fig1.

Figure 2 shows the TF measurement results.
It looks healthy though the coherence at high frequency is not so good due to the reduction of excitation amplitude.
So, the suspension seems to be healthy but still close to rubbing.
I hope the situation will be getting better as increasing the temperature.
