Dear all, 

I used a kind of tip to conduct AFM.

But it always shows the error message - the engage setpoint has fallen below the minimum limit -when I try to land the tip.

Is there any possible reason caused that problem?

The technical data of tip is as the following.

force constant : 2N/m ; resonant frequency : 25kHz

Thank you for any response.

Hi Arthur,

What model of AFM do you have? What mode are you using?

Can you contact our Tech support for assistance? It's AFM.Support@bruker.com

Thanks,

Teddy
